Abstract: This paper proposes RSA-based zero-knowledge proof watermark verification protocolsIt can tackle the problem of disclosing sensitive information.In the protocols，the public key encryption are used to encrypt the watermark and the watermarked data of the watermark embedding locations，the open verification of copyright watermarking is achieved through estimating the relativity of them.Furthermore，the authors research how to resist cheat-attack，and propose the way that prover and verifier can only communicate with each other to resist this attack.

摘要： 提出了一种基于RSA公钥密码体制的零知识水印验证协议，以解决通常的水印检测方案泄漏与水印相关的敏感信息的问题。协议利用公钥加密对水印及水印嵌入位置的水印化数据进行盲化处理，通过判断它们之间相关性的方法实现了版权水印的公开验证。同时，对如何抵抗骗局攻击进行了研究，提出了在协议执行过程中限制证明者P、验证者V对外通信的方法抵抗该类攻击。
