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.
