A Solution of Video Semi-fragile Watermarking of Authentication based on Binary Characteristic Strings
The binary characteristic string is calculated from I-frame by using the semi-fragile characteristic in this paper, and the binary watermarking is generated by using the characteristic string as the encryption key. This watermarking based on the content is embedded into I-frame, which is used to distinguish whether the video content remains unchanged or not. So the integrity of MPEG-4 videos I-frame is protected and authenticated. The experimental results show that the solution is robust for the operations of saving content and is fragile for the operations of modification.
