Digital rights management system with equity anonymity
一个具有公平匿名性的数字版权管理系统

The current Digit Rights Management (DRM) systems only pay much attention to the security issue, but it does not take full account of the user's purchasing privacy. By utilizing the equity anonymity technology of the e-cash, we can improve the current DRM model and make the legal users have equal purchasing anonymity. Meanwhile the system can disclose the real identities of the illegal users.
