Abstract
The introduction of an integrated data glyph, watermark, and thumb print system enables copy protection via a multi-functional device. The device, working with a secure remote server, produces a unique data glyph for each document that the user wishes to protect. Different copy protection strengths are possible and the reproduction of the document is fully controllable.
