Copyright protection as a major security demand in digital world. Watermarking techniques are proposed the intention to show the advantages and the possible weaknesses in the schemes working in the frequency domain and in the spatial domain. In this report key-frame based video watermarking method is presented. This method implant data to the each bands perform in the wavelet domain into the specific frames using key-frame extraction method. The algorithm uses frequency domain to add the watermark where it does not affect the quality of extracted watermark if the video is subjected to different types of malign attacks. Watermark is embedded in an additive way in key-frames .This method is tested on different types of video. The recommend watermarking method in frequency domain has robustness against some attacks such as sharpness, contrast, Gaussian blur and brightness. |
