• With the development of multimedia and the Internet, the problem of multimedia copyright infringement has become more and more serious. The combination of digital watermark and security protocol plays a vital role in copyright protection of multimedia in the up-to-date open network environment. Most of the existing schemes involve trusted third parties and arbitration institutions, but they are not usually credible. This paper proposes a new watermarking protocol with multiple parties based on the blockchain. The protocol involves the buyer, the seller, the cloud platform and the blockchain. In the protocol, the certificateless secret key negotiation between the buyer and the seller is utilized to avoid “Man-in-the-middle Attack”, and the cloud platform is used to perform homomorphic calculations and watermark embedding operation. By using the characteristics of the blockchain such as non-tamperability and traceability, the security and fairness of the protocol can be ensured.
