Uncompressed Video Authentication through a Chip Based Watermarking Scheme

Digital video contents now become easily available through Internet and various medium. Easy availability made digital video more popular than analog media. And it attains a sharp attention regarding its ownership. The ownership integrity can be easily violated using different video editing software. In this regard we are proposing a chip level framework in accordance with our already proposed LSB framework for video that is able to embed a color watermark logo into the video frames of a video content. The quality of original video won't degrade, because in watermarked video, the color watermark is perceptually invisible to Human Visual System (HVS). As we are proposing blind extraction scheme, at the time of extraction prior knowledge of that watermark or the original video is not required. The security is also employed with a hash function and a secret key. If a forger tries to perform watermark extraction with an inappropriate key he'll get a video frame which resembles noise. We named our proposed chip informally as BLIND CHIP as we've used blind extraction method. The robustness of the proposed framework is also proven against different intentional attacks.
