A method and apparatus for the watermarking of video data is disclosed. In one embodiment, discrete objects are extracted from the video host data. Each is assigned and embedded with a watermark. The watermark is embedded by generating the watermark, applying it to a perceptual mask of the block, spatially masking the resulting block, and re-adding the block to the result. The objects are collected into a database so that an object may be tracked as it is transformed from frame to frame of the video host data.
