Method for updating data in accordance with rights management policy

摘要

Disclosed is a computerized system and method for dynamically applying a rights management policy to a message by allowing an administrator to associate certain rights management policies with certain senders and recipients of messages, with groups of users possessing certain common criteria which define the users and groups of users, with certain attributes of the message, and with certain environmental attributes. In some embodiments, an administrator is allowed to automatically update a rights management protected message as it passes through a message transfer agent. The administrator may determine either on a regular interval or an ad-hoc basis that the message transfer agent scan the messages stored to determine whether or not the content has expired. If the content has indeed expired the administrator may take steps to have the expired content deleted entirely, refreshed with more current content, or replaced with a tombstone indicating that the original content has expired.

主权项

1. A computerized system for updating content in an electronic document, wherein the updating relies on the existence of a persisted policy scheme, said system comprising:
a rights management server operatively connected to a data communication network, said rights management server storing the persisted policy schema, and a message transfer agent computing device operatively connected to the data communication network, said agent computing device having a document store associated therewith, said agent computing device configured to execute instructions for:
accepting the electronic document into the document store via the data communication network;accessing the persisted policy schema stored on the rights management server via the data communication network;identifying one or more rights management protections associated with content of the electronic document, said rights management protections being defined by the persisted policy scheme;pre-licensing the accepted electronic document by obtaining, on behalf of a user, a use license associated with the content of the electronic document, said use license being obtained from the rights management server via the data communication network and being defined by the persisted policy scheme;determining whether the content of the electronic document has exceeded the rights management protections defined by the persisted policy scheme;modifying a portion of the content corresponding to the exceeded right management protections when the content of the electronic document has exceeded the rights management protections; andpermitting use of the modified content of the electronic document in accordance with the defined restrictions of the obtained use license.
