In this study, we propose a new image/video authentication system based on the digital signature technique. The proposed digital signature is composed of visually important and compression-tolerant features in images/videos. In the authentication process, the features of each block being evaluated are compared with the corresponding features of the block recorded in the digital signature. Authenticity is granted if the similarity is high enough. The experimental results show that the proposed techniques are not only efficient to protect security and integrity of multimedia data, but also are flexible and feasible for real applications.
