    • A system and a method for providing variable security mechanisms for securing digital content, in which a single security mechanism is not used for all content. Instead, at least one characteristic or feature of the security mechanism is varied between units, instances or categories of content. Therefore, even if unauthorized access is gained to a single unit of content, the overall integrity and security of the system for content distribution is not compromised. Preferably, security is provided though a general mechanism, which is then varied in order to provide variable, dissimilar security schemes for different types of content. By “type of content”, it is meant any of a single unit of content, a single instance of content or a single category of content. For example, for a category of content, the content may be characterized according to the identity of the content itself, such as the title of a movie for example, and/or according to the owner of a particular copy of the content. Thus, different security schemes may optionally and preferably be generated from a particular root structure. Related apparatus and methods are also provided.
    • 一种用于提供用于保护数字内容的可变安全机制的系统和方法,其中单个安全机制不用于所有内容。 相反,安全机制的至少一个特性或特征在单元,实例或内容类别之间变化。 因此,即使未授权的访问获得到单个内容单元,内容分发系统的整体完整性和安全性也不会受到损害。 优选地,通过通用机制来提供安全性,然后进行变化,以便为不同类型的内容提供可变的不同的安全方案。 根据“内容类型”,它是指单个内容单元,单个内容实例或单个内容类别中的任何一个。 例如,对于内容的类别,内容可以根据内容本身的身份(例如电影的标题)和/或根据内容的特定副本的所有者来表征。 因此,可以可选地且优选地从特定根结构生成不同的安全方案。 还提供了相关的装置和方法。
