Abstract: Considering the problems of the frequent participation of buyers and the involvement of too many third parties in current digital copyright protection protocols, a secure and efficient watermarking protocol is proposed. This protocol utilizes the homomorphic Paillier encryption algorithm and the iris recognition technology to solve the anonymity problem, unbinding problem, piracy tracing problem and some other relevant secure problems. In addition, to ensure the confidentiality and completeness of the communication data, the communication data between the participants in the transaction are expressed in the forms of encryption, digital signature authentication and so on. The buyers select the trading application to finish the operations of information transmission and purchase, which makes this protocol closed to the daily trading model and easy to realize as well.

Key words: digital copyright protection, digital watermarking protocol, Paillier encryption, iris recognition technology, trading application
