- W2473448611 abstract "It is becoming easier to alter a digital content in ways that are difficult to detect. If this digital content was a medical video or a critical video piece of evidence in a legal case, this form of modification might pose serious problems. In order to deal with this issue, this paper presents a fragile watermarking scheme to authenticate uncompressed video using key frames, singular value decomposition and Faber Schauder discrete wavelet transform. The video key frames are extracted where each key frame presents a video sequence and comes in the end of it. Then the Faber Schauder dominant blocks singular values of every frame are computed and placed in a matrix to be used later as a mark. This mark is inserted in the key frame salient regions. These operations are repeated for every sequence separately. Using this fragile watermarking scheme we show that any frame alteration can be detected and the video quality remains high. The method is fast and fragile to any modification." @default.
