Abstract:

As one of the important branches of multimedia data security, digital watermarking has been developed rapidly because it can provide copyright protection and source certification for open network. Nowadays, digital watermarking has been widely used in the protection of multimedia information. Previously, most of the digital watermarking schemes do not consider the security of the watermark itself and the security of the verification process. In this paper, a secure watermarking scheme is proposed. In this scheme, the data owner uses sparse representation of the original data to embed watermark, and cloud can use the encrypted data and fuzzy watermark from the data owner and user to verify copyright. Since the scheme can provide security protection to both the watermark itself and the whole verification process, it is suitable for cloud application. The experimental results show that the proposed scheme is an invisible watermark scheme and can correctly verify copyright while protecting the data security of parties, including the watermark. Besides, the scheme has good robustness against noise attack.

Key words: secure digital watermarking, cloud-assisted, sparse representation, digital security, cloud verification
