    • A trusted rendering system for use in a system for controlling the distribution and use of digital works. A trusted rendering system facilitates the protection of rendered digital works which have been rendered on a system which controls the distribution and use of digital works through the use of dynamically generated watermark information that is embedded in the rendered output. The watermark data typically provides information relating to the owner of the digital work, the rights associated with the rendered copy of the digital work and when and where the digital work was rendered. This information will typically aid in deterring or preventing unauthorized copying of the rendered work to be made. The system for controlling distribution and use of digital works provides for attaching persistent usage rights to a digital work. Digital works are transferred between repositories which are used to request and grant access to digital works. Such repositories are also coupled to credit servers which provide for payment of any fees incurred as a result of accessing a digital work.
    • 一种用于控制数字作品分发和使用的系统中的可信渲染系统。 可信赖的渲染系统有助于保护已经在通过使用嵌入在渲染输出中的动态生成的水印信息来控制数字作品的分发和使用的系统上呈现的渲染数字作品。 水印数据通常提供与数字作品的所有者有关的信息,与数字作品的渲染副本相关联的权利以及何时何地呈现数字作品。 这些信息通常有助于阻止或阻止未经授权的复制所作出的作品。 用于控制数字作品分发和使用的系统提供了对数字作品的持久使用权。 数字作品在用于请求和授予对数字作品的访问的存储库之间进行转移。 这些存储库还耦合到信用服务器,其提供用于支付由于访问数字作业而产生的任何费用。
