基于水印和密码技术的数字版权保护模式

综合考虑数字版权保护的实际需求和安全隐患，结合水印技术和密码技术提出了一种新的数字版权保护模式(WCDRM)，模式中共有7个实体，其中有3个权威机构。讨论了模式的注册过程、在线交易过程、验证过程和仲裁过程，该模式可以提供多种服务。模式将作者身份标识、版权发行机构身份标识和消费者身份标识作为盲信息水印数据隐藏在数据作品中，还采用了密码算法、密码协议和水印协议技术，可以抵抗各种算法攻击和协议攻击，具有较高的安全性和较好的实用性

Watermarks and Cryptography Based Model for Digital Rights Management

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.
