A Distributed Information Retrieval Approach for Copyright Protection

Developments in telecommunications technology has opened up the possibility of circumventing intellectual property in the digital world, outside the legal and technical methods proposed for copyright protection, the information retrieval is considered as a computer field helping to protect these rights by proposing methods of search, analysis and comparison for protected documents. This article proposes an approach based on the distributed information retrieval allowing the detection of any unlawful manipulation for copyrighted works. In particular, we propose an architecture of a distributed information retrieval system on a peer-to-peer network as well as the specific architecture of its nodes, in addition, a double indexation (local & distributed) was proposed.
