基于机器指纹的版权控制系统的设计与实现

Design and Implementation of Digital Right Management Based onMachine Fingerprint

设计了一种基于机器指纹的版权控制系统, 该系统采用一种新的许可证密钥产生、分配和认证方法, 使内容许可证跟用户的机器指纹和用户的个人信息绑定. 数字内容采取高强度的对称密钥算法加密, 只能在本地机器按照内容许可证的要求进行解密及可控使用,从而在整个数字内容生命周期实行版权保护.

A new_style digital rights management system based on machine fingerprint is designed in this paper.The secure trade and the rights management of digital contents on Internet with binding user's machine fingerprint to license file,using rights management and plug_in technology and encrypting digital contents,are realized in the system.First,a system model and its protocol mechanism are introduced in the paper.The way of digital rights controlling the system use is discussed.The realization of the system and its test conclusion are given.
