发明名称 Protecting content objects with rights management information
摘要 A method for protecting a content object with rights management information begins by creating a content object. Permissions are assigned to the content object, an encryption key is generated, and a content protection utility is cloned. The cloned content protection utility, the encryption key, and the permissions are appended to the content object to create a composite object. The composite object is encrypted with the encryption key to create a protected content object.
