NDLI: On the security and practicality of a buyer seller watermarking protocol for DRM

Content Provider	ACM Digital Library
Author	Z'aba, Muhammad Reza Poh, Geong Sen
Abstract	A buyer seller watermarking (BSW) protocol allows a seller of digital content to prove to a third party that a buyer illegally distributed copies of content when these copies are found. It also protects an honest buyer from being falsely accused of such an act by the seller. We examine the security and practicality of a recent BSW protocol for Digital Rights Management (BSW-DRM) proposed in SIN 2009. We show that the protocol contains weaknesses, which may result in successful replay, modification and content piracy. Furthermore, the heavy reliance on the fully trusted Certificate Authority has its security concern and it is also less practical to be applied in current digital content distribution systems. We further suggest possible improvements based on the many protocols proposed prior to this protocol.
