Straightforward adaptations of results for still images watermarking have led to non-secure video watermarking algorithms. The very speci?c nature of digital video has indeed to be considered so that robustness and security issues are handled e?ciently. As a result, a novel video watermarking scheme is presented in this paper: security is achieved by using a smooth time-dependent strength and payload is encoded in the phase di?erence between several signals transmitted along non-interfering communication channels. Moreover, temporal synchronization can be done in a blind manner on the detector side. The proposed scheme is ?nally proven to be secure against traditional intravideo collusion attacks and robust against MPEG compression.
