一种面向Android平台的多媒体数字版权管理系统

Multimedia DRM System for Android Platforms

针对移动终端多媒体音视频数字版权保护问题,设计了一种面向Android平台的数字版权保护方案。该方案采用3DES加密算法,并将数字许可证与移动终端设备硬件绑定,实现了多媒体安全播放和使用控制,以及终端设备间的数字权利分享。实验结果表明,该方案安全性高、加解密速度快,使用控制功能满足了Android平台数字内容版权保护的实际需求。

For digital rights management of mobile multimedia in mobile terminals,a Digital Rights Management （DRM） approach for Android platforms was proposed.The solution adopts 3DES encryption algorithm and binds digital license with hardware of the device to implement usage of control and secure display of multimedia contents.Meanwhile,sharing digital rights between devices was supported in this approach.A prototype confirms that the solution has the features of high security and faster encryption speed.Otherwise,functions of usage of control can meet the practical requirements for digital rights management with Android platforms.
