| 摘 要： | 限制性太强的数字版权保护系统使得用户的一些合法权益无法得到保证, 用户希望合法购买的数字内容可以在其多台终端设备上使用并且允许终端设备的部分硬件变更。针对该问题, 提出具有硬件适应性的多设备内容共享与版权保护方法。该方法支持动态的内容共享, 满足共享节点间独立性, 并兼顾版权的安全性。同时, 该方法可以解决现有硬件自适应版权保护机制中存在的设备无关性问题, 适用于各类设备, 无需针对不同类型设备分别订制方案。

| Abstract: | Too restrictive digital rights management system makes that some legitimate rights of users cannot be guaranteed. Users hope the legally purchased content can be rendered on their multiple end devices and the hardware alteration of the rendering device is allowed. To solve this problem, a hardware adaptive copyright protection method for multiple devices of end-user is proposed. The method supports dynamic contents sharing, satisfies the independence between shared nodes and takes into account the copyright security. The method can solve the device independence problem in the existing hardware adaptive copyright protection mechanism, which is suitable for the devices of various types without the need for customized solutions respectively. |
