Abstract:

After considering actual needs for digital rights manager and security rask, a new watermark and cryptography based model for digital rights management (DRM) is proposed, which includes seven objects, three of them are authenticity. The copyright registering, online transactions, watermarking detecting and dispute resolutions of this model are studied. This DRM model is designed to be flexible and support various business and using cases. In the DRM model, the author’s ID, distributor’s ID and the consumer’s ID are regard as some of watermarks information, which can be used for binding information for digital content, some of the cryptographic solutions, protocols and watermarks protocols are also adopted to prevent from algorithm and protocol attack. This DRM model has good security and practicability.

Key words: digital rights manager; watermarks and cryptography-based digital rights manager model, watermark, cryptography
