20:12:01 Barcodes in the photos.
A new technique based on shorthand promises to obscure bar codes in the picture, creating documents forgery-proof. The algorithm is called Concealogram and was created by Joseph Rosen (pictured), a professor at the University of the Negev in Israel, and developed by the local departments of electrical and computer engineering. The system uses points, characteristic of 2D barcodes, and encrypts the data in a file, but only when printing on photo paper, storing out like holograms, in any part of the photo all the information needed to reconstruct the code bar used, thus preventing possible errors resulting from damage to the photo itself.
