This forgery-preventing fingerprinting technique can be used to affordably verify the legitimacy of documents. Developed by a team out of Newcastle University in the UK, the method involves taking a picture of a paper document with a regular camera, which will still be able to create an individualized digital fingerprint for the file.
Security engineering researcher Dr Feng Hao explains "What we have shown is that every piece of paper contains unique intrinsic features just as every person has unique intrinsic biometric features." The digital fingerprinting technique uses an ordinary source of light and a normal camera. The method only requires 1.3 seconds to capture these features, and will generate a corresponding textile fingerprint based on the snapshot.
