Fingerprinting for Copyright Protection in P2P Context
Haibo Gao, Wenjuan Zeng, Zhen Chen · 2010
Despite the immense potential of Peer-to-Peer (P2P) networks in facilitating collaborative applications, they are generally considered to be free havens for pirated multimedia content. Ensuring the proper distribution and usage of multimedia content in P2P networks has become increasingly critical. Encryption can provide multimedia contents with the desired security during transmission, which disappears after they are decrypted. Digital fingerprinting is an emerging technology to protect multimedia data from illegal redistribution, where each distributed copy is labeled with unique identification information. In this paper, we propose a fingerprinting scheme for copyright protection of P2P systems, where each user gets a slightly different version of the same content.
