Mask-based interactive watermarking protocol for video
Sabu Emmanuel, Mohan Kankanhalli · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2001
Digital video broadcasting is increasingly being adopted all over the world. The video broadcasters would require that the viewable contents of the pay channels be protected from unauthorized copying and distribution by subscribers, which is copyright protection. The subscribers would require that they be not wrongfully implicated by the broadcasters and thus ensure customer's rights protection. In this paper we present an integrated solution to address the copyright protection and customers rights protection for a video broadcasting environment. The copyright protection is addressed using a mask based watermarking technique and customer's rights protection is obtained through the use of an interactive watermarking protocol.
