In the digital right management value chain, digital watermarking technology plays a very important role in digital product's security, especially on its usage tracking and copyrights infringement authentication. However, watermark procedures can only effectively support copyright protection processes if they are applied as part of an appropriate watermark protocol. In this regard, a number of watermark protocols have been proposed in the literature and have been shown to facilitate the use of digital watermarking technology as copyright protection. One example of such protocols is the anonymous buyer-seller watermarking protocol. Although there are a number of protocols that have been proposed in the literature and provide suitable solutions, they are mainly designed as a watermarking protocol for the first-hand market and are unsuitable for second-hand transactions. As the complexity of online transaction increases, so does the size of the digital second-hand market. In this paper, we present a new buyer-seller watermark protocol that addresses the needs of customer's rights problem in the digital secondary market. The proposed protocol consists of five sub-protocols that cover the registration process, watermarking process for the first, second and third-hand transactions as well as the identification & arbitration processes. This paper provides analysis that compares the proposed protocols with existing state-of-the-arts and shows that it has met not only all the buyer's and seller's requirements in the traditional sense but also accommodates the same requirements in the secondary market.

A High Security Buyer-Seller Watermark Protocol based on Iris Biometric http://researchonline.ljmu.ac.uk/id/eprint/4275/ Article LJMU has developed LJMU Research Online for users to access the research output of the University more effectively.Abstract: With the development of digital watermarking technology, digital watermarking protocol is now drawing the attention for protecting copyrights of digital products. However, the copyright protection is fully protected by watermark technology if it is employed a suitable protocol between the rights owner and the customer. Therefore, currently, there are a number of buyer-seller watermarking protocols proposed, however, an anonymous problem and collusion problem are still unsolved completely. Thus, this paper proposes a high security watermark protocol based on iris biometric for resolving these problems. In addition, this paper also produces watermarking generation mechanism Chunlin Song which aims to improve the efficiency of the whole mechanism. Finally, the investigation indicates that the proposed buyer-seller watermark protocol takes care of the security concerns of all parties involved, and the proposed scheme could also find an illegal copy of the content, the violators can be traced back.
