Video Content Authentication Technique Based on Invariant Feature Detection and Cloud Watermark

With the broad spread of the digital video, its integrality and reality is drawn more and more attention. In this paper, an invariant feature detection technique based on the shot segmentation approach is proposed. And a scheme of video content authentication based on the invariant feature detection and cloud watermark is proposed to solve the tampering detection in the space domain and the time domain for the video content. Through some experiments and the analysis of the related results, this proposed scheme is performed to be well performance on real time and compute complexity.
