    • Systems and methods are disclosed for managing and protecting electronic content and applications. Applications, content, and/or users can be given credentials by one or more credentialing authorities upon satisfaction of a set of requirements. Rights management software/hardware is used to attach and detect these credentials, and to enforce rules that indicate how content and applications may be used if certain credentials are present or absent. In one embodiment an application may condition access to a piece of electronic content upon the content's possession of a credential from a first entity, while the content may condition access upon the application's possession of a credential from a second entity and/or the user's possession of a credential from a third entity. Use of credentials in this manner enables a wide variety of relatively complex and flexible control arrangements to be put in place and enforced with relatively simple rights management technology.
    • 公开了用于管理和保护电子内容和应用的系统和方法。 应用程序,内容和/或用户可以在满足一组要求后由一个或多个凭证机构提供凭证。 权限管理软件/硬件用于附加和检测这些凭证,并且执行指示如果存在或不存在某些凭证时可以使用内容和应用程序的规则。 在一个实施例中,应用可以在内容拥有来自第一实体的证书的情况下调节对一段电子内容的访问,而内容可以在应用程序拥有来自第二实体的凭证和/或用户拥有 来自第三实体的凭证。 以这种方式使用凭证可以通过相对简单的权限管理技术实现各种各样相对复杂和灵活的控制安排并执行。
