Real-time, distributed, transactional, hybrid watermarking method to provide trace-ability and copyright protection of digital content in peer-to-peer networks

摘要

A method of enabling real-time watermarking of digital works prior to distribution of digital work. The method entails maintaining a central repository of fingerprint meta-data of digital works so that upon a request for insertion of watermark in a digital work, the watermarking application communicates with the central repository and receives fingerprint meta-data which provides information regarding where to insert said watermarks. The method also enables a method of extraction of watermarks based on fingerprint meta-data. Furthermore, the fingerprint meta-data can be utilized to search for digital works of similar characteristics and to block digital works that are illegal copies of the digital work.
