A real-time video watermarking algorithm for authentication of small-business wireless surveillance networks

摘要: In some business applications, all kinds of cameras sensors are employed in a distributed way to capture videos for different tasks such as surveillance. Once illegal actions happen, then somebody or organization wants forge replace surveillance video clips destroy evidences obtain profits. How authenticate the genuineness and integrity source trace information leak becomes growing requirement these small businesses. Fortunately, watermark just provides an effective technology resolve this issue. This paper proposes real-time watermarking scheme MPEG, where firstly exploits fast scenes segmentation original sequence adaptively selects appropriate be embedded. Furthermore, visual model is utilized modulate strength. Watermarks embedded by adjusting number bit1 bitstreams through changing level run-level pairs. Experiment results show little loss quality also exhibit excellent robustness against many attacks. As directly detected domain, detection reality. addition, embedding strategy guarantees that bit rate not increased experiments validate it.
