Paper Abstract

With the wide application of multimedia data, multimedia content protection becomes urgent. Until now, various means have been reported that can be classified into several types according to their functionalities, such as data encryption, digital watermarking, or data authentication. They are used to protect multimedia data's confidentiality, ownership, and integrity, respectively. A wavelet-based multifeature semifragile multimedia authentication scheme is proposed. According to the approximation component and the energy relationship between the subbands of the detail component, global feature and local feature are both generated. Then, the global watermark and local watermark are generated from global feature and local feature, respectively. Two watermarks are then embedded into the multimedia data themselves, in the wavelet domain. Both the feature extraction and embedding processes are controlled by secret keys to improve the security of the proposed scheme. On the receiver side, the extracted watermark and the one generated from the received image are compared to determine the tampered location. A new authentication method is designed, and it is proved valid in the experiments. This authentication scheme is robust to general compression; sensitive to cutting, pasting, or modification; efficient in real-time operation; and secure for practical applications.
