Abstract	:	In this thesis, we propose two video watermarks based on the novel ideas of statistical inuis-ibility and content-synchronized placement. We present a mathematical framework designedto facilitate collusion analysis and thereby enable protection from this important class of at-tacks. We define statistical invisibility and show that it is not only a property that supportsthe desired resistance to such attacks, but that it can also be easily induced using a spatiallylocalized image-dependent approach. To construct the watermark, the notion of a watermark'sfootprint, the spatial locations over which its energy is spread, is introduced. By defining lo-calized footprints with regular structures, e-g., sets of subframes within each frame, currentimage watermarks can immediately be applied at the subframe level. Results are presented todemonstrate the effectiveness of the algorithms. Comparisons are made with the well-knownJAWS and CDMA video watermarks, as well as the StirMark 3.1 benchmarking suite..
