E-Governance

E-Commerce: Business has been looking for ways to increase their profits and market share. The search for more efficient ways of doing business has been driving another revolution in the conduct of business .This revolution is known as electronic commerce which is any purchasing or selling through an electronic communications medium. Business planners in institutions and organizations now see technology not only as a supportive cofactor, but as a key strategic tool. They see electronic commerce as a “wave of future”. Information technology has revolutionized and digitalized economic activity, and made it a truly global phenomenon .One of the most visible icons of the IT Revolution is the internet – the world wise web. Which is a gigantic anarchic network of computers world wide, which is essentially used for communicating, interaction, interactive long distance computing and exchange of information giving rise to a host of applications from military and government to business, education and entertainment? E-commerce exists because of internet. It has been born on the net and is growing with the net. It involves carrying business on and through the net. E-commerce is a product of the digital economy. It is a source of a paradigm shift, in redefining technology, individual and global societies as well as national and global economies. Electronic commerce is a symbolic integration of communications, data management, and security capabilities to allow business applications within different organizations to automatically exchange information related to the sale if goods and services. Communication services support the transfer of information from the originator to the recipient. Data management services define the exchange

format of the information. Security mechanisms authenticate the source of information, guarantee the integrity of the information received, prevent disclosure of information to inappropriate users, and document that the information was received by the intended recipient. Prior to the development of e-commerce, the process of marketing and selling goods was a mass-marketing and sales-force driven process. Customers were viewed as passive targets of advertising “campaigns” .Selling was conducted in well-insulated “channels” .Consumers were trapped by geographical and social boundaries, unable to search widely for the best price and quality. E-commerce has challenged much of this traditional business thinking. E-Commerce Defined: “The use of internet and the WEB to transact business. More formally, digitally enabled

commercial

transactions

between

and

among

organizations

and

individuals.” “Electronic commerce is commerce via any electronic media, such as TV, fax, and online networks. Internet-based commerce makes use of any Internet facility and service. Web-based commerce focuses on the opportunity of the World Wide Web apparatus, in particular, its ubiquity and its ease of use.” Benefits/Features of E-Commerce: Electronic commerce increases the speed, accuracy, and efficiency of business and personal transactions. The benefits of E-commerce include the following: •

Ubiquity: E-commerce is ubiquitous, meaning that it is available just about everywhere, at all times. It liberates the market from being restricted to a physical space and makes it possible to shop from your desktop, at home, at work, or even from your car using mobile commerce .From customer point of view, ubiquity reduces transaction costs – the costs of participating in a market. To transact it is no longer necessary to spend time and money traveling to market. At a broader level, the ubiquity of e-commerce lowers

the cognitive energy required to transact in a marketplace. Cognitive energy refers to the mental effort required to complete a task. •

Global Reach: E-commerce technology permits commercial transactions to cross cultural and national boundaries far more conveniently and cost effectively than is true in traditional commerce. As a result, the potential market size for e-commerce merchants is roughly equal to the size of the world’s online population. The total number of users or customers an ecommerce business can obtain is a measure of its reach.

•

Universal Standards: The technical standards for conducting e-commerce are universal standards – they are shared by all nations around the world. The universal technical standards of e-commerce greatly lower the market entry costs - the cost merchants must pay just to bring their goods to market. At the same time, for consumers, universal standards reduce search cost – the effort required to find a suitable products.

•

Richness: Information richness refers to the complexity and content of a message.

•

Interactivity: E-commerce technologies are interactive, meaning they allow for two-way communication between merchant and consumer .It allows an online merchant to engage a consumer in ways similar to a face-to face experience , but on a much more massive , global scale.

•

Information Density: the internet and the Web vastly increase information density –the total amount and quality of information available to all market participants, consumers, and merchants alike. E-commerce technologies reduce information collection, storage, processing, and communication costs .At the sale time; these technologies increase greatly, the accuracy and timeliness of information-making information more useful and important than ever. As a result information becomes more plentiful, cheaper and of higher quality.

•

Personalization/Customization:

E-commerce

technologies

permit

personalization – merchants can target their marketing messages to specific individuals by adjusting the message to a person’s name, interests, and past purchases. The technology also permits customization –changing the delivered product or service based on a user’s preference or prior behavior. Given the interactive nature of e-commerce technology, a great deal of information about the consumer can be gathered in the marketplace at the moment of purchase. With the increase in information density, a great deal of information about the consumer’s past purchases and behavior can be stored and used by online merchants. The result is increase in the level of personalization and customization. Types of E-Commerce: There are different types of e-commerce and many different ways to characterize these types. The five major types of e-commerce are: 1. B2C 2. B2B 3. C2C 4. P2P 5. M-Commerce B2C: (Business-to-Consumer) The most commonly discussed type of e-commerce is Business-to-Consumer (B2C) e-commerce, in which online business attempt to reach individual consumers is done .It has grown exponentially since 1995, and is the type of e-commerce that most consumers are likely to encounter . Within the B2C category there are many different types of business models: portals, online retailers, content providers, transaction brokers, market creators , service providers , and community providers. B2B: (Business-to-Business)

In this type of e-commerce, one business focuses on selling to other business .It is the largest form of e-commerce. The ultimate size of B2B e-commerce could be huge . At first, B2B e-commerce primarily involved inter-business exchanges, but a number of other B2B business models have developed, including e-distribution, B2B service providers, matchmakers, and info-mediaries that are widening the use of e-commerce. C2C: Consumer-to-Consumer C2C e-commerce provides a way for consumers to sell to each other, with the help of an online market maker such as the auction site .In C2C e-commerce, the consumer prepares the product for market, places the product for auction or sale, and relies on the market maker to provide catalog, search engine, and transaction clearing capabilities so that products can be easily displayed, discovered, and paid for. P2P: (Peer-to-Peer) Peer-to-Peer technology enables Internet users to share files and computer resources directly without having to go through a central Web server. In peer-to-peer’s purest form, no intermediary is required. Entrepreneurs and venture capitalists have attempted to adapt various aspects of peer-to-peer (P2P) e-commerce. E.g. Napster.com established to aid internet users in finding and sharing music files (mp3 files). It is partially peer-to-peer because it relies on a central database to show which users are sharing music files. M-commerce: Mobile commerce or m-commerce refers to the use of wireless digital devices to enable transactions on the Web. These devices utilize wireless networks to connect cell phones and handheld devices to the Web. Once connected, mobile consumers can conduct many types of transactions, including stock trades, banking, travel reservations, and more.

B2G: Business to Government E-Commerce Business Models: A business model is a set of planned activities (sometimes referred to as business process) designed to result in a profit in a marketplace. The business model is at the center of the business plan. A business plan is a document that describes a firm’s business model. An e-commerce business model aims to use and leverage the unique qualities of the internet and the World Wide Web. There are Eight Key Ingredients of a Business Model: 1. Value proposition: It defines how a company’s product or service fulfils the needs of the customers. To develop and/or analyze a proposition, the following questions need to be answered : - Why will customers choose to business with your firm instead of another company? - What will your firm provide that other firms do not and cannot? From the consumer point of view, successful e-commerce value propositions include: personalization and customization of product offerings, reduction of product search costs, reduction of price discovery costs, and facilitation of transactions by managing product delivery. 2. Revenue model: The firm’s revenue model describes how the firm will earn revenue, generate profits, and produce a superior return on invested capital. The function of business organizations is both to generate profits and to produce returns on invested capital that exceed alternative investments. * The advertising model: A website that offers its users content, services, and/or products also provides a forum for advertisements and receives fees from advertisers. Those websites that are

able to attract the greatest viewer ship and are able to retain user attention are able to charge higher advertising rates. * Subscription Revenue Model: In the subscription revenue model, a Web site that offers its users content or services charges a subscription fee for access to some or all of its offerings. * Transaction fee revenue model: In this model a company receives a fee for enabling or executing a transaction. (e.g. Online auction websites taking some commission from buyer as well as the seller). * Sales Revenue Model: In the sales revenue model, a company derives revenue by selling goods, information, or services to customers. E.g. amazon.com * Affiliate Revenue model: In the affiliate revenue model, sites that steer business to an “affiliate” receive a referral fee or percentage of the revenue from any resulting sales. 3. Market Opportunity: The term market opportunity refers to the company’s intended marketplace and the overall potential financial opportunities available to the firm in that marketplace. The market opportunity is usually divided into smaller market niches. The realistic market opportunity is defined by the revenue potential in each of the market niches. 4. Competitive Environment: The firm’s competitive environment refers to the other companies operating in the same marketplace selling similar products. The competitive environment for a company is influenced by several factors: how many competitors are active, how large their operations are, what the market share of each competitor is, how profitable these firms are, and how they price their products. 5. Competitive Advantage:

Firms achieve a competitive advantage when they can produce a superior product a superior product and/or bring the product to market at lower than most, or all, of their competitors. Firms also compete on scope .Some firms can develop global markets while other firms can only develop a national or regional market .Firms that can provide superior products at lowest cost on global basis are truly advantaged. 6. Market strategy: Market strategy is the plan the company put together that details exactly how the company intend to enter the market and attract new customers. 7. Organizational Development: Describes how the company will organize the work that needs to be accomplished. 8. Management Team: Employees of the company responsible for making the business model work.

Categorizing E-Commerce Business Models: Major B2C business models: There are a number of different models being used in the B2C e-commerce arena. The major models include the following: •

Portal:-Offers powerful search tools plus an integrated package of content services;

typically

utilizes

a

combined

subscription/advertising

revenue/transaction fee model may be general or specialized. •

E-tailer: - Online version of traditional retailer; includes virtual merchants (online retail stores), clicks and mortar e-tailers (online distribution channel for a company that also has a physical store); catalog merchants (online

version of direct mail catalog); online malls (online version of mall); manufacturers selling directly over the Web. •

Content Provider: - Information and entertainment companies that provide digital content over the Web; typically utilizes an advertising, subscription, or affiliate referral fee revenue model.

•

Transaction broker: - Process online sales transactions; typically utilizes a transaction fee revenue model.

•

Market creator: - Uses Internet technology to create markets that brings buyers and sellers together; typically utilize a transaction fee revenue model.

•

Service provider: - Offers services online.

•

Community provider: - Provides an online community of like-minded individuals for networking and information sharing; revenue is generated by referral fees, advertising, and subscription.

Major B2B business models: The major business models used to date in B2B arena include: •

Hub, also known as marketplace/exchange – electronic market place where suppliers and commercial purchasers can conduct transactions; may be general (a horizontal marketplace) or specialized (a vertical marketplace).

•

E-distributor: - Supplies products directly to individual businesses.

•

B2B service provider: - Sells business services to other firms.

Major C2C business models: A variety of business models can be found in the customer-to-customer ecommerce, peer-to-peer e-commerce, and m-commerce areas: •

C2C business models connect consumers with other consumers .The most successful has been the market creator business model used by eBay.com.

•

P2P business models enable consumers to share files and services via Web without common servers. A challenge has been finding a revenue model that works.

•

M-commerce business models take traditional e-commerce models and leverage emerging wireless technologies to permit mobile access to the Web.

•

E-commerce enablers business models focus on providing the infrastructure necessary for e-commerce companies to exist, grow, and prosper.

Key business concepts and strategies applicable to e-commerce: •

Industry structure : The nature of players in an industry and their relative bargaining power – by changing the basis of competition among rivals , the barriers to entry , the threat of new substitute products , the strength of suppliers , and the bargaining power of buyers.

•

Industry value chains: The set of activities performed in an industry by suppliers, manufacturers, transporters, distributors and retailers that transforms raw inputs into final products and services – by reducing the cost of information and other transaction costs.

•

Firm value chains: The set of activities performed within an individual firm to create final products from raw inputs – by increasing operational efficiency.

•

Business strategy: A set of plans for achieving superior long-term returns on the capital invested in a firm – by offering unique ways to differentiate products, obtain cost advantages, compete globally, or compete in a narrow market or product segment.

Technology Infrastructure for E-Commerce The Internet and World Wide Web E-Commerce Infrastructure The Internet: Technology Background The Internet is an interconnected network of thousands of networks and millions of computers (sometimes called as host computers or just hosts) linking business ,

educational institutions , government agencies , and individuals together .The internet provides services such as e-mail, news-groups, shopping, research , instant messaging , music videos and news . No one organization controls the Internet or how it functions, nor it is owned by anybody, yet it has provided the infrastructure for a transformation in commerce, scientific research, and culture .The word internet is derived from the word internet work or the connecting together of two or more computer networks. The World Wide Web is one of the internet’s most popular services, providing access to over one billion Web pages , which are documents created in a programming language called HTML and which can contain text , graphics , audio, video, and other objects, as well as “hyperlinks” that permit a user to jump from one page to another. The Internet: Key Technology Concepts; Based in the definition , the internet means a network that uses the IP (Internet Protocol) addressing scheme, supports the Transmission Control Protocol (TCP), and ,makes services available to users much like a telephone system makes voice and data services available to the public. Behind this formal definition are three extremely important concepts that are the basis for understanding the Internet: packet switching, the TCP/IP communications protocol, and client/server computing .Although the Internet has evolved and changed dramatically, these three concepts are at the core of how the Internet functions today and are the foundation for Internet. Packet Switching: It is a method of slicing digital messages into parcels called “packets” sending the packets along different communication paths as they become available, and then reassembling the packets once they arrive at their destination .Prior to the development of packet switching, early computer networks used leased, dedicated telephone circuits to communicate with terminals and other computers. In packet-switched networks, messages are first broken down into packets. Appended to each packet are digital codes that indicate a source address (the origination point) and the destination address, as well as sequencing information and

error-control information for the packet. Rather than being sent directly to the destination, in a packet network, the packets travel from computer to computer until they reach their destination. The computers are called Routers. Routers are special purpose computers that interconnect thousands of different computer networks that make up the internet and route packets along to their ultimate destination as they travel. To ensure that packets take the best available path towards their destination, the routers use computer programs called routing algorithms. Packet switching makes full use of almost all available communication lines and capacity. If some lines are disabled or too busy, the packets can be sent on any available line that eventually leads to the destination point. TCP/IP: TCP refers to the Transmission Control Protocol. IP refers to the Internet Protocol. A protocol is a set of rules for formatting, ordering, compressing, and error checking messages. It may also specify the speed of transmission and means by which devices on the network will indicate they have stopped sending and/or receiving messages. Protocols can be implemented in either hardware or software .TCP/IP is implemented in Web software called server software .It is the agreed upon protocol for transmitting data packets over the Web. TCP establishes connections among sending and receiving Web computers, handles the assembly of packets at the point of transmission, and their reassembly at the receiving end. IP addresses: TCP handles the packet zing and routing of Internet messages. IP provides the Internet’s addressing scheme .Every computer connected to the Internet must be assigned an address – otherwise it cannot send or receive TCP packets .When a user sign’s onto the Internet using a dial-up telephone modem, the computer is assigned a temporary address by the Internet service provider. Internet addresses known as IP addresses, are 32-bit numbers that appear as a series of four separate numbers marked off by periods such as 201.61.186.227. Each of the four numbers can range from 0-255. This “dotted quad” addressing scheme contains up to 4 billion addresses of the computer ( 2 to the 32nd power).The leftmost

number typically indicates the network address of the computer , while remaining numbers help to identify the specific computer within the group that is sending (or receiving) messages. Domain Names and URLs: Most people cannot remember 32-bit numbers .IP addresses can be represented by a natural language convention called domain names. The domain name system (DNS) allows expressions to stand for numeric IP addresses. Uniform Resource Locators (URLs ) are addresses used by Web browsers to identify the location of content on the web, also use domain names as a part of the URL.A typical URL contains the protocol to be used when accessing the address, followed by its location. The protocol used is HTTP (Hypertext Transfer Protocol).A URL can have more than one paths. Client/Server computing: It is a model of computing in which very powerful personal computers called Clients are connected together in a network together with one or more server computers. These clients are sufficiently powerful to accomplish complex tasks such as displaying rich graphics, storing large files, and processing graphics and sound files, all on a local desktop or hand held device. Servers are networked computers dedicated to common functions that their client machines on the network need. Such as storing files, software applications, utility programs such as Web connections, and printers. Other Internet Protocols: SMTP: Simple mail transfer protocol POP

: Post Office Protocol

IMAP: Internet message access protocol FTP

: File Transfer Protocol for transferring files

SSL : Secure Socket Layers for Security

E-Commerce Security Environment It is difficult to estimate the actual amount of e-commerce crime for a variety of reasons. In many instances, e-commerce crimes are not reported because companies ear of losing the trust of legitimate customers. And even when crimes are reported, it may be hard to quantify the losses incurred .The most serious losses involved theft of proprietary information and financial fraud. Online credit card fraud is perhaps the most high profile form of e-commerce crime. In some cases, the criminals aim to just deface, vandalize and/or disrupt a Web site, rather than steal goods or services. The cost of such an attack includes not only the time and effort to make repairs to the site but also damage done to the site’s reputation and image as well as revenues lost as a result of the attack. Estimates of the overall cost of the various forms of cyber vandalism range into billions. What is Good E-Commerce Security? What is a secure commercial transaction? Anytime a user goes into a market place , he/she takes risks, including the loss of privacy (information about what you purchased).The prime risk as a customer is that you do not get what you paid for. As a merchant in the market, you don’t get paid for what you sell, Thieves take merchandise and then either walks off without paying anything, or pay you with a fraudulent instrument, stolen credit card, or forged currency. Burglary, breaking and entering, embezzlement, trespass, malicious destruction, vandalism – all crimes in traditional commercial environment – is also present in e-commerce. However, reducing risks in e-commerce is a complex process that involves new technologies, organizational policies and procedures, and

new laws and industry standards that empower law enforcement officials to investigate and prosecute offenders. Security Threats in the E-Commerce Environment: From the technology perspective, there are three key points of vulnerability when dealing with e-commerce: the client, the server and the communication pipeline.

Malicious Code It includes a variety of threats such as viruses, worms, Trojan horses, and “bad applets”. A virus is a computer program that has the ability to replicate or make copies of it, and spread to other files. In addition to the ability to replicate, most computer viruses deliver a “payload” (destroying files, reformatting the computers hard drive or causing programs to rum improperly. A Trojan horse does something other than expected. The Trojan horse is not itself a virus because it does not replicate, but is often a way for viruses or other malicious code to be introduced into a computer system. Bad applets also referred to as malicious mobile code, are expected to become an increasing problem as java and Active X controls become more commonplace. Malicious code is a threat to the system’s integrity and continued operation, often changing how a system functions or altering documents created on the system. In many cases the user is unaware of the attack until it affects the system and the data on the system. Hacking and Cyber vandalism: A hacker is an individual who intends to gain unauthorized access to a computer system . Within the hacking community, the term cracker is typically used to denote a hacker with criminal intent although in the public press, the terms hacker and cracker are used interchangeably. Hackers and crackers get unauthorized access by

finding weaknesses in the security procedures of Web sites and computer system , often taking advantages of various features of internet that make it an open system that is easy to use. Cyber vandalism is intentionally disrupting, defacing, or even destroying the site. Group of hackers called as “tiger teams” are used by corporate security departments to test their own security measures. By hiring hackers to break into the system from outside, the company can identify weaknesses in the computer systems.

Dimensions of E-Commerce security: There are six dimensions to e-commerce security: 1. Integrity 2. No repudiation 3. Authenticity 4. Confidentiality 5. Privacy 6. Availability Integrity refers to the ability to ensure that information being displayed on a Web site , or transmitted or received over the internet , has not been altered in any way by an unauthorized party.e.g. An unauthorized person intercepts and changes the contents of an online communication, such as by redirecting a blank wire transfer into a different account, the integrity of the message has been compromised because the communication no longer represents what the original sender intended. Non repudiation refers to the ability to ensure that e-commerce participants do not deny (I.e. repudiate) their online actions. Authenticity refers to the ability to identify the identity of a person or entity with whom you are dealing on the internet. How does the customer know that the Web

site operator is who it claims to be? How can the merchant be assured that the customer is really who he/she say he/she is? Someone who claims to be someone they are not is “spoofing” or misinterpreting themselves. Confidentiality refers to the ability to ensure that messages and data are available only to those who are to view them. Confidentiality is something confused with privacy, which refers to the ability to control the use of information a customer provides about himself or herself to an e-commerce merchant. Availability refers to the ability to ensure that an e-commerce site continues to function as intended. E-Commerce security is designed to protect these six dimensions. When any one of them is compromised, it is a security issue. Risk management Risk: “The possibility of loss or injury.” E-commerce risk involves understanding potential problems that might occur in the business and affect on success. Risk management is an activity undertaken to lessen the impact on potentially adverse events on business. Risk management is an investment .There is costs associated with it. The investment in risk management depends upon the nature of the business. Risk Assessment: The first step is to inventory the information and knowledge assets of E-commerce site and company. What information is at risk? Is it customer information, proprietary designs, business activities, secret processes, or other internal information, such as price schedules, executive compensation, or payroll? For each type of information try to estimate the losses for the firm. Based on the quantified list of risks, one can start to develop a security policy I.e a set of statements prioritizing the information risks, identifying acceptable risk targets, and identifying the mechanisms for achieving these targets.

Technology Solutions protecting internet communications Because e-commerce transactions must flow over the public internet, and therefore involved thousands of routers and servers through which the transaction packets flow, security experts believe the greatest security threats occur at the level of internet communications. This is very different from a private network where a dedicated communication line is established between the two parties. A number of tools are available to protect security of internet communications, the most basic of which is message encryption. ENCRYPTION Encryption is the process of transforming plain text data in to cipher text that can not read by anyone outsider of the sender and the receiver. The purpose of encryption is (a) to secured stored information and (b) to secure information transmission . Encryptions can provide four of the six key dimensions of E- Commerce security. •

Message integrity – provides assurance that the message has not been altered

•

Non repudiation – prevents the user from denying he or she sent the message.

•

Authentication – provides verification of the identity of the person (or machine) sending the message.

Confidentiality – gives assurance that the message was not read by others. This transformation of plain text to cipher text is accomplished by using a key or cipher. A key (or cipher) is any method of transforming plain text to cipher text. Encryption can be practiced since the earliest form of writing and commercial transaction. Ancient Egyptian and Phoenician commercial records were encrypted using substitution and transposition ciphers. In a substitution cipher, every occurrence of given letter is replaced systematically by another letter. For instance, if we used the cipher ”letter plus two”- meaning replace every letter in a word with a new letter

two places forward – then the word “hello” in plain text would transformed into the following cipher text :”jgnnq”. In a transposition cipher, the ordering of the letters of each word is changed in some systematic way. Symmetric Key Encryption: In order to decipher this message, the receiver would have to know the secret cipher that was used to encrypt the plain text. This is called symmetric key encryption or secret key encryption. In symmetric key encryption, both the sender and the receiver use the same key to encrypt and decrypt the message. How do the sender and the receiver have the same key? They have to send tit over some communication media or exchange the key in person .The possibilities for substitution and transposition ciphers are endless, but they all suffer from common flaws. First, in the digital age, computers are so powerful and fast as these ancient means of encryption can be broken quickly. Second, symmetric key encryptions require that both parties share the same key. In order to share the same key, they should send the over a presumable insecure medium where it could be stolen and used to decipher messages. If the secret key lost or stolen, entire encryption system fails. Third, in commercial use where we are not all parts of the same team or army, you would need a separate key for each of the parties with whom you transacted, that is, one key for the bank, another for a department store, and another for the government. In large population of users, this could result in as many as n (n - 1) keys. In population of millions of Internet users, thousands of millions of keys would be needed to accommodate all e-commerce customers (established at about 35 million purchasers in the United States). Potentially, (35 millions) 2 different keys could be needed. Clearly this situation would be too unwieldy to work in practice. Modern encryption system are digital. The ciphers or keys used to transform plain text in to cipher text are digital strings. Computers store text or other data as binary strings composed of 0s and 1s. For instance, the binary representations of the capital letters “A” in ASCII computer code is accomplished with eight binary digits

(bits):01000001. One in which digital strings can be transformed into cipher text is by multiplying each letter by another binary number, say, an eight- bit key number 01010101. If we multiplied every digit character in our text messages by this eightbit key, sent the encrypted message to a friend along with the secret eight-bit key, the friend could decode the message easily. The strength of modern security protection is measured in terms of the length of the binary key used to encrypt the data. In the above example, the eight-bit key is easily deciphered because there are only 28 or 256 possibilities. If the intruder knows you are using eight-bit key, then he or she could decode the message in a few seconds using a modern desktop PC just using the brute force method of checking each of the 256 possible keys. For this reason, modern digital encryption systems use keys with 56,128,256, or 512 binary digits. With encryption of 512 digits, there are 2512possiblities to check out. It is estimated that all the computers in the world would need to work for ten years before stumbling upon the answer. The most widely used systematic key encryption on the internet today is the Data Encryption Standard (DES) developed by the National Security Agency (NSA) and IBM in the 1950s. DES uses 56-bit encryption key. To cope with much faster computers, Triple DES – essentially encrypting the message three times each with a separate key, has improved it recently. There are many other symmetric key systems; DES requires a different set of keys for each set of transactions. PUBLIC KEY CRYPTOGRAPHY Two mathematically related digital keys are used: a public key and private key. The private is kept secret by the owner, and public is widely disseminated. Both keys can be used to encrypt and decrypt the message. However, once the keys are used to encrypt a message, that same key can not be used to unencrypt the message. To check the confidentiality of the message and ensured it has not been altered in transit, a hash function is used first to create a digest of the message. A hash function is an algorithm that produces a fixed length number called a hash or

message digest. A hash function can be simple, and count the number of digital “1s”in a message, or it can more complex, and produce a128-bit number that reflects the number of 0s and 1s, the number of 00s, 11s, and so on. One more step is required to ensure the authenticity of the message, and to ensure the no repudiation, the sender the encrypts the entire block of cipher text one more time using the sender’s private key. This produces a digital signature (also called an e-signature) or “signed” cipher text that can be sent over the internet. Digital envelop - a uses symmetric encryption for large documents, but public key encryption to encrypt and the symmetric key. PAYMENT SYSTEM: TYPES OF PAYMENT SYSTEM There are five main types of payment systems: 1. Cash 2. Checking transfer 3.

Credit cards

4.

Stored value and

5. Accumulating balance. Cash Cash, which is legal tender, defined by a national authority to represent value, is the most common form of payment in terms of number of transactions. The key feature of cash is that it is instantly convertible into other forms of value without the intermediation of any other institution. For instance, free airline miles are not cash because they are not instantly convertible into other forms of value- they require intermediation of by a third party (the airline) in order to be exchanged for value (an airline ticket) . Private organizations sometimes create a form of private cash called scrip that can be instantly redeemed by participating organizations for goods or cash. Example includes Green Stamps and other forms of consumer loyalty currency.

Checking Transfer Checking Transfers which are transferred directly via a signed draft or check from a consumer’s checking account to a merchant or other individual are the second most common form of payments in terms of number of transactions and the most common in terms of total amount spent. Checks can be used for both small and large transactions, although typically they are not used for micro payments. Checks have some float (it can take up to ten days for out-of-state checks to clear) and the unspent balances can earn interest. Checks are not anonymous and required third party institutions to work. Checks also introduce security risks for merchants. They can be forged more easily than cash; hence authentication is required. For merchants, checks also present some additional risk compared to cash because they can be cancelled before they clear the account or they may bounce if there is not enough money in the account. Money orders, cashier checks, and traveler’s checks are ensured checks that address some of the limitations of personal checks described above. Ensured checks reduced the security risk of a personal check by requiring an up-front payment to a trusted third party – A bank or money transferred company such as American express, Wells Fargo, or Western Union. These trusted third parties then issue a guaranteed payment draft called money order that is as good as cash, although less anonymous. Merchants are guaranteed the funds in an any transaction with an ensured check. Trusted third parties make money by charging consumers a fee and receiving interest on the money consumers deposited with them. Ensured checks provide merchants with lower risk, but they add cost for the consumer. In return, consumers have a payment instrument that is accepted almost everywhere and in some cases is insured against loss. Credit card A credit card represents an account that extends credit to consumer, permits consumers to purchase items while deferring payment, and allows consumers to make payment to multiple vendors at one time. Credit card association such as Visa and MasterCard are nonprofit associations that set standards for the issuing banks –

such as Citibank- that actually issue the credit cards and process transactions. Other third parties (called processing centers or clearinghouses) usually handle verification of accounts and balances. Credit card issuing banks act as financial intermediaries, minimizing the risk to the transacting parties. Stored Value Accounts created by depositing funds in to an account and from which funds are paid out or withdrawn as needed are stored-value payment systems. Stored value payment systems are similar in respects to checking transfers – which also stored funds – but do not involve writing a check. Example includes debit card, gift certificates, prepaid cards and smart cards. Debit cards look like credit cards, but rather than providing access to a line of credit, they instead immediately debit a checking or other demand deposit account. For many consumers, the use of debit card eliminates the need to write a paper check. Be cause debit cards are dependent on funds being available in consumer’s bank account, however, large purchases are still generally paid for by credit card. Accumulating balance Accounts that accumulate expenditure to which consumers make periodic payments are Accumulating balance payment systems. Traditional examples include utility, phone, and credit card bills s, all of which accumulate balances, usually over a specified period (typically a month), and are paid in full at the end of the period. Digital Checking Payment Systems have many advantages: 1. They do not require consumers to reveal account information to other individuals when settling an auction. 2. They do not require consumers to continually send sensitive financial information over the WEB. 3. They are less expensive than credit cards for merchants. And 4. They are much faster than paper-based traditional checking.

Digital Payment Systems and the Wireless Web: Wireless device usage has exploded and is expected to continue as new products and services are introduced .From cellular phones to pagers and personal digital assistants (PDAs), wireless devices have spurred the creation of new Web sites to support them. One area in which there is substantial interest is in financial services, including stock trading and money transfer. B2B Payment System: B2B payment systems pose special challenges and are much more complex than B2C payments, in large part because of the complexity involved in business purchasing. Sometimes a dozen of more documents may be needed to consummate the transaction, including purchase order , invoice , bill of landing or shipping , insurance papers , financial documents , regulatory documents , credit verifications , service documents (if any) , authentication , letters of credit (foreign transactions), and payment methods or instruments . In addition, B2B payment systems must link to existing ERP (Enterprise Resource Planning) systems that integrate inventory, production, shipping, and other corporate data , and into EDI (Electronic Data Interchange) systems which are systems that replace paper-based purchase orders with electronic equivalents . The B2B payment market is actually much larger than the B2C market because of the larger size of transactions among businesses and the frequency of transactions

Online Market Research: Market research involves gathering information that will help a firm identify potential products and customers .There are two general types of market research . Primary research involves gathering first-hand information using techniques such as surveys, personal interviews and focus groups. This type of research is typically

used to gain feedback on brands, products, or new marketing campaigns where no previous study has been done. Secondary research relies on existing, published information as the basis for analyzing the market. Both primary and secondary research can be completed online more efficiently, less expensively, and more accurately than offline. In addition to two different approaches to market research, there are two types of data to be studied. Quantitative data is data that can be expressed as a number, such as percentage. Quantitative data can be analyzed using statistical programs that identify relationship between certain variables, or factors that affect how someone responds. Qualitative data is data that cannot be easily quantified, such as opinions, survey questions that yield qualitative responses are analyzed by grouping responses into similar sub segments based on the answer given. One type of analysis is content analysis, which tries to identify the major categories of responses given.

Primary Research: Surveys and questionnaires are the most popular and frequently used market research tools. Using a survey instrument, which is a list of questions, researchers can approach groups of people to ask their views on virtually any imaginable topic. Online surveys can be typically being administered more quickly and less expensively than traditional mail or telephone surveys. Companies can hire an outside market research firm to conduct the survey or create and administer their own. Online surveys also make it possible to track respondents and follow up with those who haven’t yet completed survey, which help to improve response rates, the percentage of people who complete a survey. A low response rate can damage the validity, or believability, of a survey’s results. Feedback forms, which ask users to provide input regarding a site’s operations in a set format, are another type of inline survey. Requesting regular

input from site visitors may provide more qualitative data, which is more difficult to analyze, but the resulting information can assist in improving and enhancing site performance. Personal interviews are another primary research tool. The interview is generally guided by a set of questions very similar to survey instrument. Although it is more difficult to incorporate personal interviews within Web sites, it is possible to conduct research online via live chat or e-mail, with trained researcher interacting with the study participant’s .Personal interviews offer an opportunity to gather more in-depth information on a topic. In some cases, personal interviews are used as second phase of a research project, following initial information gathering by survey. Secondary Research: It involves gathering information using WEB sites as the information source. The Key to being efficient and effective as a researcher is identifying the WEB sites most likely to provide answers to the questions posed in the research .By establishing and agreeing on the key question to be answered through market research , as well as why that information will be useful , researchers can zero in on their information needs. Understanding how the information will impact other decisions also helps to further refine information collection. Online Marketing Technologies that support Online Marketing: •

Direct E-mail marketing:

E-mail marketing messages sent directly to interested users (direct e-mail marketing) have proven to be one of the most effective forms of marketing communications. The key to effective direct e-mail marketing is “interested users”. Direct e-mail marketing is not spam. SPAM involves sending unsolicited e-mail to a mass audience of Internet users who have expressed no interest in the product. Instead, direct e-mail marketing messages are sent to an “opt in” audience of Internet users who have expressed at one time or another interest in receiving messages from the advertiser. By sending e-mail to an opt-in audience, advertisers are targeting interested customers. Because of the comparatively high response rates and low cost, direct e-mail marketing is the fastest growing form of online marketing. The primary cost of e-mail marketing is for the purchase of the list of names to which the e-mail will be sent. Due to the cost savings possible with e-mail, the short time to market, and high response rates, companies are expected to increasingly use e-mail to communicate directly with customers.
