ABSTRACT:
This invention is directed to a method and system for generating and using digital fingerprints in copies of an electronic document so that it is possible to determine at least one from among a group of purchasers colluding to forge a digital fingerprint. The present method and system is suitable for copyright protection and can be used to identify purchasers who illegally redistribute copies even after the document has been manipulated.
