Zero-knowledge proof watermark verification protocols based on RSA

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.
