Abstract
The specification discloses a system and related method for tracking access to digital information that involves combining biometric information of a person seeking access with the digital information and a digital signature. Each person who accesses the digital information has their biometric and digital signatures combined in this manner. Thus, the digital information itself reflects who has accessed the information. Where the digital information is a video, the combining of the biometric and digital signatures is done on a frame-by-frame basis.
