intro: Decode Your License .................................................................................................................................................................................. Using a cool little program I dug up on the web, and a scanner I was able to decode the barcodes on the back of my NY drivers license, and find out what information people get when they scan it. I'm pretty sure that just decoding the barcode is not illegal, but some of the other things I describe probably are, so let those be just proof of concept. All the times my license (well technically my permit, but its all the same) appears, I mess up the barcodes a bit so (hopefully) no one can get my information. Personally I don't care, but theres probably some good reasons why I should not let it out so I'm just being safe.

step 1: Materials Most people probably have this stuff: 1. Scanner 2. License/Permit from any state ( I think there are a few states ids that do not work, but most should) 3. Swipe Barcode Program 4. A Hex converter (more on this later) 5. Photoshop or similar program 6. Optional 1d barcode decoder

File Downloads swipebarcode.jar (85 KB) [NOTE: When saving, if you see .tmp as the file ext, rename it to 'swipebarcode.jar']

http://www.instructables.com/id/Decode-Your-License/

step 2: Procedure All of this is fairly straight forward. 1. Scan the back of your license / permit using a medium - high resolution. The resolution should be set so that the 2d barcode is about 2000 pixels long. 2. Open up the image in Photoshop and cut out the 2d barcode. The 2d barcode is the one on the bottom in the picture. Most states use the PDF-417 (Portable Data File, with 17 modules each containing 4 bars and spaces, thus 417). Edit the barcode so that it is exactly 2000 or less pixels long because that is the maximum the program will allow, and save it. 3. Open swipe toolkit pdf417 barcode reader, available to download in the last step, and load your barcode into it. Click decode image, and a window with all your information should pop up. The picture shows the window that I got ( I removed thinks I should probably care about). As you can see, you can view the information processed, in raw bytes, or in hex. An interesting thing to note is if your card contains your social security number, some states put it on and some states don't.

step 3: Legality becomes iffy here http://www.cyanosoft.com/download/index.htm Cyansoft makes a pdf 417 barcode encoder, which you can use to modify the barcode. If you select raw bytes(you can also select hex if you want to use a hex editor to edit the information) on how the decoded information is shown in the pdf 417 reader, examine it and you should be able to pick out your information such as d.o.b, name, license number, etc. You can edit that information, copy the selection into cyansoft's barcode encoder, and tweak it to look like the original barcode. Some of the settings you may need to change are the Error correction level, the number of columns and rows, and the bar width. The overall purpose of tweaking the barcode is to get it to look and read the same before, just with the modified data. To test out the modded barcode, export it as an image and run it through the decoder again, if it works great, if not just keep tweaking the settings in the encoder until it looks exactly like the original. You now have your modded barcode, but what should you do with it?

http://www.instructables.com/id/Decode-Your-License/

step 4: From this point on everythings definitely illegal Ive never tried these, so don't blame me if you screw up and ruin your license. If you want to use the fake barcode you just make on your license, there are many possible ways to transfer it. The easiest is probably to erase the old barcode with some acetone and paper towels, and when your sure its completely erased, carefully print directly onto the license. The only problem with this method is that you would need a high density printer (thermal transfer or laser), and would have to be extremely careful that it printed in the right spot nice and cleanly. Another method could be to clean off the old barcode with acetone, and then print out the new one on a transparency and affix it to your license. The problem with this method are that it would be easy to tell its fake, unless done really carefully. Remember if you are changing a piece of information that is on the front you have to change it on the license too. It doesn't matter if the id scans 21, if it says 18 on the front they are not going to accept it. (Note: Most licenses also have a 1d barcode on the back too. It contains much less information then the 2d barcode. To edit it you will need to find out what specific type of barcode it is, there are many sites online with pictures of different barcodes that can help you. Then download a decoder for that type, and decipher the information they give you, see if it matches up with your license number, dob, etc. Then change it and re encode it using a program for that type of barcode.)

Oct 24, 2006. 12:21 AM REPLY I worked staffing a company that was deploying the new barcode system to a southern state. I was given secure information about the barcodes. You are correct that they do include printed information. However, the barcode also includes an encrypted image file of the photograph that is on the front of the license. The biometrics firm used an existing 2d barcode to create this embedded image. When a picture is taken a biometric readout is created and hypothetically any camera at a stop light, mall, airport or your seven-eleven could then be used as a capture device to help track known or suspected criminals. The biometric firm had plans on selling decoders to hotels, stores, gas stations, etc. in an attempt to help reduce fraud. The companies would have three choices of how to use the product. First it would simply display the decoded image on a screen for visual comparison. This would have been the cheaper solution. The second solution would generate a revenue stream for the state. For a subscription fee the scan could then be sent, via vpn, to a state computer for a triple check. In other words the state would provide a third database copy of the image for comparison to the printed front copy and the decoded copy. It would also provide publicly available information to the company and automatically populate the companies data base with said information. The third option was to combine option number two with a photo taken by the merchant using a web cam and then the image would be biometrically matched with records on file with the state to provide a positive id. The second and the third options provide the state with a number of revenue streams. One from the subscription service, another for the database access and database population and perhaps most importantly it would provide local, state, and federal law enforcement with an ability track individuals with outstanding warrants. The cost of implementation has thus far been cost prohibitive and since 9/11 there has been some fear of the system being misused for the identification of government operatives by terrorist cells within and outside of the United States.

As far as I know, it's a PDF-417 Symbology. The reason why I'm asking is that I have a Barcode Scanner that supports the PDF-417 Symbology. I designed such barcode & managed to scan it, but when I scan the one on the drivers license it couldn't pick it up.Could you please help?

chriskarnaze says:

May 24, 2007. 4:25 PM REPLY Can you recommend any pdf417 encoders that will work with that decoder? I have tried several but can't produce any barcodes that the decoder will decode. It says "BarCode not found" with dimensions -1 x -1. The decoder will decode the bar code on my driver's license, so I'm not sure if the problem is with the encoders I'm using or the way the barcode image is being prepared for the decoder. Thanks

Feb 4, 2008. 12:45 PM REPLY i've been carded at grocery and liquor stores before that wanted my license,i told them they could look at it but not scan it because i didn't want my info in their data base and if they had a problem with that i'll shop somewhere else. so far in all my years buying alcohol(i'm 52)nobody has turned me down and i doubt they ever will. it's your license and your information,you decide what happens with it.and be very careful of big brother,those who give up freedom in exchange for safety do not deserve nor will get either.

I have done everything so far...But I cannot properly use BCDmaker to make a file that can be read by the decoder program. I first of all scanned my license, then opened it up in paintbrush, and selected just the barcode. Then I re-pasted that into new paintbrush document and got rid of outside white edges. Then I scanned it with the Java program that decodes. I got all my info (in the processed category). I then modified it all to what I wanted (dob change) and name change just to see if this program works. Then I copied text and saved it in note pad. I then opened it in BCDmaker and did new template. I then did Various Code Value: Then I imported that text file. It gave me a barcode which was similar to the one on my actual license. I then exported it into a picture file. I then opened that in paintbrush and got rid of the excess white again and pasted it so the pic is just the barcode. When I ran it through scanner, it said it is unrecognizable, and not a valid barcode. What do I need to do to modify this correctly?

http://www.instructables.com/id/Decode-Your-License/

I have tried some different settings in the template manager, but I don't know what to do. Any help would be great thanks

I know there must be an easier way to do this, Does anyone know about any special characters- raw or hex -that may be the hidden key?

Mar 15, 2007. 3:03 PM REPLY I was wondering if anyone could help me out with; the decoding of, and/or the meaning to some of the encrypted readouts, from the 2d barcode pdf417 ? I have nj DL as well and things like<9>, pop up at random. I assume it is part of the security feature, because when I replace the squares I get when using a hex editor with them at random spots some information that even "Swipe" didn't decrypt shows up upon re rendering and analyzing. I just can't figure out the pattern. In different spots of replacing square randomly- info pops up seemingly out of sequence, but when all are replaced then the info is a bunch of jumble. I get <16>, and <10> also but the "<9>" makes them readable, at random. I am assuming the"<10>" is code for a break in the line. If anyone can give me a direction I would greatly appreciate it.

Tetranitrate says:

Oct 20, 2006. 3:01 PM REPLY Yes, the police have scanners in their car, they use them to save time instead of typing in all the information; however, the most common places scanners are used is at bars, clubs, and liquor stores. The first thing most kids ask when buying a fake ID is "Is it scannable?". Ive heard arguments debating who would go in the store and buy the hooch, and scannability was the big issue ex: "Well I look the oldest and my ID is chalked to say I'm 23, but its not scannable" "Do you know if they scan here" "Yeah I think they do, so we should send in Jessica, she looks the youngest, but she has her sisters ID which is scannable" 2 hours later "GESSHhikkkka, I mmmaay n0t telll you thissss eneeough, but ::hiccup:: I...I...I lllurrvvee youuu" "OHHh youu, yerour jusss saYinggg that ::giggles:: ::burps:: ::pukes:: ::passes out:: ::farts:: Ahh, the sweet cherished memories of youth.

mrmath says:

Oct 20, 2006. 8:39 PM REPLY No wonder I've never seen it happen. The police always are in their car, and I'm in mine. And the scanable licenses didn't come around until after I was old enough, and looked old enough.

Oct 20, 2006. 6:33 PM REPLY

Even if you are 100% legal, don't you think it's kinda creepy that they are scanning and saving the data? Do they have a privacy policy or a data retention policy, or do they consider that they just now own the information and can do with it as they please?

spinach_dip says:

Oct 20, 2006. 6:57 PM REPLY

I'm talking about the liquor store retaining your data. Also, this barcode seems to be called a PDF417 barcode

Tetranitrate says:

Oct 20, 2006. 7:01 PM REPLY Yeah many stores keep and some even sell the information they get when they swipe the id, and I mentioned it was a PDF417 in the instructable.

Anyway, if you get the reader software, here's a file you can download to try it out: http://www.barcodeman.com/faq/pdftwedum.gif which came from this page here: http://www.barcodeman.com/faq/2d.php It's not from anyone's ID, so you will have to switch over to "show raw bytes", but at least you can give it a workout.

TVarmy says:

Oct 23, 2006. 6:00 PM REPLY I have an NJ license. I ran it through that program, but all I got was random numbers in the raw bytes and hex, and nothing in the processed box. I'd send the output, but I don't want my social security number flying around. Anyone know if NJ follows a different system or something? I tried multiple, high res scans. And the strip is plenty clean.

TVarmy says:

Oct 23, 2006. 6:39 PM REPLY Never mind. I tried converting it to greyscale in photoshop and boxing it only around the code (no whitespace) and it worked. Pretty cool. My ssn wasn't on it, for those of NJ who were curious.

atombomb45 says:

Oct 22, 2006. 9:44 PM REPLY Its good that you had the fore site to "edit" your barcode before you put it online. Im going to school for computer security, and you wouldn't belive the things people will do with their own information. Mind if I show this to my class?

Tetranitrate says:

Oct 22, 2006. 11:54 PM REPLY Yeah, I tried to make sure that I got rid of anything that could be used against me, and sure it would be cool to use this in your class.
