Secure Multimedia Content Delivery with Multiparty Multilevel DRM Architecture

For scalability of business, multiparty multilevel digital rights management (DRM) architecture, where a multimedia content is delivered by an owner to a consumer through several levels of distributors has been suggested as an alternative to the traditional two party (buyer-seller) DRM architecture. A combination of cryptographic and watermarking techniques are usually used for secure content delivery and protecting the rights of seller and buyer in the two party DRM architecture. in a multiparty multilevel DRM architecture the cryptographic and watermarking mechanism need to ensure the secure delivery of the content as well as the security concerns of the owner, multiple levels of the distributors and the consumer. In this paper, we propose a mechanism which takes care of the above security issues, for delivering multimedia content through multiparty multilevel DRM architecture.
