    TAMPERING DETECTION IN VIDEO USING WATERMARKING METHOD
    Shreni A Patil*, A J Shikalgar

    Video authentication is a process to establish the fidelity of a digital video. A video authentication system ensures the integrity of digital video and verifies that the video taken into use has not been doctored. In digital watermarking, customized data is embedded in a digital content like an image, video and audio for digital right management, copy control or authentication. For authentication, fragile or semi-fragile watermarks are usually used, where the authentication systems reject any modification made to a digital content. Mainly video watermarking techniques are divided into two types: frequency domain and spatial domain. The idea is to authenticate the digital data by adding watermarking information and extract it back successfully for verification purpose. In commercial video processing systems, watermark embedding and detection need to be performed in real time. For still pictures, detection of the robust watermark can take as long as a few seconds, but this delay is unacceptable for motion pictures especially when the frame rate is fast.
