Digital video is one of a kind of digital data which contains more information than an image. Data digital such as a video is easily copied, transferred, edited, altered, or manipulated. Once a digital video is manipulated, the integrity of video changes. In some cases, we need to know authenticity of the video. For example, a court need to decide if a video is genuine or has been manipulated. Fragile watermarking provides a technique to authenticate originality of a video. In the fragile watermarking technique, a data signal that called watermark is inserted into a host video become to a watermarked video without affecting its perceptual quality. The watermark can be extracted again from the video. If the watermarked video is manipulated by using a software, then the extracted watermarked is fragile or broken. Compared to the original watermark, the broken watermark is indication that the video has been altered.
