Content Protection for MPEG-4 Video with Watermarking
This paper presents a MPEG-4 video CODEC based watermarking scheme to protect video content. This scheme provides dual zrotection for intellectual property rights (IPR), utilizing error propagation in temporal MCP. Watermark is embedded into I-VOP, and is adjusted before IVOP is reconstructed as reference VOP. During decoding, the embedded watermark in I-VOP is adjusted by the same way as in encoding. Only users with authorization can adjust the watermark correctly during decoding to get good video quality. For illegal users the video is also accessible but with bad quality because of the propagation of error caused by adjusted watermark in I-VOP. The watermark in I-VOP exists anytime once its embedded. This scheme has the virtue of providing dual protection with little expense of time and computation. Some experimental results are given and discussed in the end.
