A Novel Authentication Mechanism for Improving the Creditability of DRM System
A novel authentication mechanism for improving the creditability of DRM system is proposed in this paper. The new authentication mechanism is the three-factor authentication composed of biometric watermarking, cryptography, and digital signature. The obtained biometric watermark is embedded into the content by combining with the RSA algorithm. Considering the requirement of security strength, the novel authentication architecture added a authentication strength choosing module is set up to meet the demands of the security criterion. Based on the proposed authentication mechanism, the creditability of DRM system is established.
