2D Barcodes and Encryption
Question – Why would I use encrypted information with 2D symbols?
Answer – In my last column, I discussed the use of digital signatures placed into 2D symbols. In that column I described how digital signatures are used for content verification and document or author authentication.
In some ways, encryption can be seen as the next step in document security. Rather than adding a private key to authenticate a document, encryption can be used to totally secure the contents of the 2D symbol, using DES standards. This allows the creator to ensure that the contents cannot be seen or read without having the ability to decrypt the encryption method used.
An example of the use of this technology is its use on the State of New York for automobile insurance. In New York, a major problem has been the number of uninsured vehicles on the road. To address some of the issues there, the State initiated and implemented a system that requires insurers to gather approximately 600 bytes of information about the insured and the insured vehicle, and transmit this information to the state agency. As well the required that the insurers issue ‘Proof of Insurance’ ID cards containing a PDF417 symbol.
This symbol contains not only pertinent information about the vehicle and its owner, but also requires that the insurer encrypt a portion of the information and include it in the transmission to the state as well as place it in the printed symbol on the ID card.
This method of encryption can be used in any other application where it is necessary to hide or secure private information in the symbol, and have that information available only to those who can decrypt it.
Users of 2D symbologies can decide when and how to use it, but for heavily regulated industries such as health care, insurance and financial sectors, this may address some of the reporting requirements of HIIPA and Sarbanes Oxley.
