Abstract: A technique for establishing a perimeter of accountability for usage of digital assets such as data files. The accountability model not only tracks authorized users' access to files, but monitors passage of such files to uncontrollable removable storage media or through network connections and the like which may indicate possible abuse of access. In accordance with a preferred embodiment, an autonomous independent agent process running at a point of use, such as in the background of a client operating system kernel, interrupts requests for access to resources. The agent process senses low level system events, filters, aggregates them, and makes reports to a journaling server. The journaling server analyzes sequences of low level events to detect when aggregate events of interest occur, such as “FileEdit”, network file transfers and the like. Reports can be generated to provide an understanding of how digital assets have been accessed, used or communicated by individuals in an enterprise.

Abstract: A technique for establishing usage control over digital assets such as computer files. The system model not only tracks authorized users' access to files, but monitors passage of such files to uncontrollable removable storage media or through network connections and the like which may indicate possible abuse of access rights. In accordance with a preferred embodiment, an autonomous independent agent process running at a point of use, such a background process in a client operating system kernel, interrupts requests for access to resources. The agent process senses low level system events, filters, and aggregates them. A policy engine analyzes sequences of aggregate events to determine when policy violations occur.

Abstract: A front cover is provided with an open area to accommodate visual displays, keyboards, switches, joy sticks and the like. A back cover, nestingly interfitting therewith, is closed, but provided with a recess, encompassing most of its back area. One or more identical nesting interfitting intermediate frames may be nested and stacked between the back cover and the front cover to form a package of any desired volume. The frames, back cover, and front cover are provided with means for mounting functional elements such as electrical circuit boards. The front cover and intermediate frames are provided with peripheral circumferential ribs. These ribs, and the slots therebetween, provide for a great variety of ways to mount the package, as does the rear recess in the back plate. The front cover may be identical or nearly identical to the intermediate frames. Functional elements may be mounted to the covers and frames during manufacture such that the covers and frames act as protective carriers during manufacture.

Abstract: An interactive terminal which is capable of complete hand-held operation with total freedom of position and location is provided. The terminal incorporates a self contained full 128-character keyboard, a 20-character alphanumeric readout, and a 1000-character memory. The terminal allows the generation of all 128 ASCII characters plus "break." In order to assure review of any message, a conveniently positioned scroll switch is incorporated to advance or roll back any messsage in the memory for presentation on the display.When previous messages are displayed and incoming information is being received by the terminal, the light intensity of the displayed messages modulates to indicate to the operator that information is being received but not displayed. The unique, totally portable, hand-held interactive terminal is provided with a 20 key keyboard which is operated with one hand, while the other hand selects one of four different information levels for each key.
