A DRM Based on New Anonymous Buyer-Seller Watermarking Protocol
Liya Chen · Information Security and Communications Privacy · 2010
For weaker collusion tolerance of the anonymous Buyer-Seller watermarking protocol, or fairly great complexity of the protocol for assuring it, the paper proposes a new anonymous watermarking protocol and gives an evaluation. As an invention in new protocol, anonymous watermarking is generated by seller and programmed partially with a random permutation function by believable CA. It improves the collusion tolerance and assures that watermarking could be generated by using, and without transferring, the original content.
