ABSTRACT:
A system for enhancing security of electronic documents distribution wherein electronic documents are fingerprinted with one or more modifications to the document text. The text modifications may be selected so that multiple copies of the same master document will all have the same meaning. By examining text modifications in an unauthorized copy, one can identify the authorized source. The ability to detect the source of a copy discourages unauthorized distribution. This electronic document distribution system may find particular application on the Internet.
