Abstract :
We present a new integrity watermark based on hologram techniques for document authentication. We focus on ID-Card watermarks. The main goal is to illustrate the use of computer-generated hologram coding techniques, to produce content-related data to be embedded into the personal data printed on an identification card with watermarking techniques. We call this special application of an integrity watermark technique a hologram watermark
