  • System and methods for granular access control
    Patent number: 9147080
    Abstract: A method and system for granular access control. An access control system allows a user or administrator to restrict access to electronic documents on a granular basis. Access may be restricted for individual data objects, types of objects, or even on a byte-by-byte basis. When a user attempts to access the electronic document, the access control system determines what parts, if any, of the document the user is permitted to access, and retrieves only those parts for access by the user. Data objects may include, for example, audio, video, graphics, or text.
