The data file is to be sent to a destination device that is external to the network. The method also includes selectively applying information protection to the data file at the gateway prior to sending the data file to the destination device.

  • Enhancing digital rights management system security through policy enforcement
    Publication number: 20050257271
    Abstract: In order to allow for security beyond revocation lists, a policy regarding when permissions may be granted (in the form of a rights document, e.g. a use license or a certificate) is enforced. When a request is made for a rights document, the requester submits an account certificate which includes certain metadata regarding the requester. This metadata is analyzed to determine whether it meets a specific policy before the request is granted. If the request is not granted, the cause of the rejection may be overcome, for example by updating or upgrading some system component (hardware or software) in the requesting system. In certain cases, such an update to overcome a policy-based rejection may be performed transparently to the user.
