Buyer Seller Watermarking Protocol for Digital Rights Management

摘要

E-commerce is emerging as an alternative inexpensive solution to traditional selling of products through shops. Sale of electronic data such as software, audio/video data, books etc. poses a problem as digital data can be easily replicated, modified and distributed. Watermarks were introduced as a means to establish ownership of digital data and check unauthorized reuse of copyrighted material. A good e-distribution system should be able to protect rights of both buyer and seller; ensure secure and confidential transactions; determine correct source of unauthorized copies. In this paper, we propose a framework for e-distribution of digital rights. This system is based on a trusted third party CA (Certification Authority) and uses PKI (public key infrastructure). Proposed system addresses problems of customer's check, copy detection, customers right, unbinding, non-repudiation and man in the middle attack.
