  • Patent number: 8296840
    Abstract: Described are methods and systems related to providing permission to a user to perform an action on a workflow driven ticket. The ticket is accessed to determine an action type to be performed on the ticket and a correlated object associated therewith. A role based permission tuple is determined based upon a role of the user. A ticket based permission tuple is determined by generating a universal permission tuple based upon the action type and generating a dependency map based upon the correlated object. The dependency map is mapped to the universal permission tuple to construct the ticket based permission tuple. The role based permission tuple is supplemented with the ticket based permission tuple, to provide the required permission to execute the action. Upon an execution of the action, the permission is partially revoked, by removing the ticket based permission tuple.
