Robust frame-based watermarking for digital video

Opening digital archives to the access of a large and spread variety of parties appears to depend on the development of more effective solutions for the transfer of rights, the protection of intellectual property and the access to digital libraries. A possible solution envisages the use of digital watermarking of multimedia works. In this paper a watermarking algorithm originally conceived for still images applications, is extended to raw video, treating it as a set of still frames. A good robustness against common image processing and geometric manipulations was achieved. Moreover, experiments with MPEG2 coding/decoding at different bit rates were carried out giving positive results.
