Combining the identification characteristics of zero-knowledge proof and blind watermark, an identity verification protocol is proposed. In this protocol, the public key encryption is used to encrypt the watermark and the watermarked data of the watermark embedding locations, and the verification of user's identity watermarking is achieved through estimating the relativity of them. Furthermore, a way which restricts the prover and verifierpsilas communication to a closed situation is put forward, and this way can resist such as brute force cheat-attack.
