Digital watermark is an active research area that has received a considerable attention in multimedia applications. Copyright protection of digital contents, as one of the most important application of digital watermark, works by watermark verification. In traditional watermark authentication scheme, a prover exposed a watermark to be present in a digital data to the verifier. However, an attacker is able to spoil or remove the watermark entirely once classified information is known. Some of previous schemes proposed as solution haven't achieved desirable result really. In this paper, we propose a secure watermark verification scheme based on commitment scheme and zero knowledge protocols in order to solve this problem. There will be no secret information that can be used for removing watermark is disclosed during the verification process. It has considerable advantages over previously proposed schemes in terms of security.
