Biological Virus Model Based Reversible Video Watermarking

Infectious video watermarking (IVW) is to embed the first watermark in encoder/decoder for the protection of video contents and to infect the watermark in different codecs whenever video contents are copied or edited. This paper presents an infectious reversible video watermarking for fast infection in the infectious watermarking model (IWM). Our method is designed by following main features. The first is that the watermark for the available period of video contents is combined with the control code for content-based video watermarking. This makes the video quality and strength be adaptively controlled in the infectious process. The second is the low complexity for fast infection. The third is to embed the infectious watermark as a unit of macro block (MB) for avoiding the delay time for extracting and recovering. Experiment results verified that the reversible watermark can be detected or recovered without loss in different codecs and the quality of recovered content has maintained in the same bit-rate.
