Method and system for modular digital watermarking of electronic files

摘要

A method and system for modular digital watermarking of electronic files is disclosed. The method involves receiving a request for an electronic file, creating a digital watermark, duplicating the file, dividing the duplicate up to produce a plurality of substantially equal sections, and inserting a watermark into each section. The document may be provided to a user. A method for historical analysis of such documents involves scanning a received document to find watermarks, and analyzing the document or watermarks for information concerning the history of the file.

主权项

1. A method for modular digital watermarking of electronic files, the method comprising:
receiving, by a first computing device, from a second computing device, a request for a copy of an electronic file; generating, by the first computing device, a digital watermark; generating, by the first computing device, a duplicate file that substantially matches the electronic file; dividing, by the first computing device, the duplicate file to produce a plurality of substantially equal sections; and overwriting a portion of each section with the digital watermark.
