Abstract

Background: In order to design secure digital right management architecture between different producers and different consumers, this paper proposes a multiparty and multilevel watermarking protocol for primary and secondary market. Comparing with the traditional buyer-seller watermarking protocols, this paper makes several outstanding achievements.

Method: First of all, this paper extends traditional buyer-seller two-party architecture to multiparty architecture which contains producer, multiply distributors, consumers, etc. Secondly, this paper pays more attention on the security issues, for example, this paper applies iris recognition technology as an advanced security method.

Conclusion: Finally, this paper also presents a second-hand market scheme to overcome the copyright issues that may happen in the real world.

Keywords: Second-hand market, iris recognition technology, watermarking protocol, multilevel, multiparty, sub-protocol, digital right management.
