Abstract: A separation management system (32) for governing interaction between code within a code base (50) operable on a computer (30) determines a region in a memory (44) of the computer (30) in which the code base (50) resides and defines container boundaries (118, 124, 130, 135) in the region for a plurality of containers (95). Each of the containers (95) contains subsets of the code (120, 126, 132, 137) that cannot be trusted. A policy (94) is created that governs interaction between the subsets of the code in the containers (95). The code base (50) is executed in the computer (30) in accordance with the policy (94) such that the subsets of code within the containers (95) are prevented from accessing code outside of their respective containers (95) when access is disallowable as indicated by the policy (94).

Abstract: A perishable media information storage mechanism, including a substrate, a data layer for recording data thereon the information storage mechanism, a reflective layer, and a protective lacquer coating. The data layer includes a material responsive to at least one predetermined data elimination factor and includes one of a decayable dye material, a liquid crystal material, a photosensitive material or a plurality of magnetoresistive memory cells. The data layer is characterized as recording data and eliminating access to data in response to at least one of a predetermined use or time factor. In addition, included is a method for fabricating a perishable media information storage mechanism including the steps of providing a substrate, forming a data layer on a surface of the substrate, forming a reflective layer on an uppermost surface of the data layer, and forming a protective coating on an uppermost surface of the reflective layer.

Abstract: A perishable media system including a media writer for writing information to a perishable media information storage mechanism, a media reader for reading information written on the perishable media information storage mechanism, a data access eliminator for eliminating access to the information written on the perishable media information storage mechanism, and an interpretation mechanism. The system operates by writing information to the perishable media information storage mechanism with the media writer, thereafter reading the information with the media reader. Once the information is read by the media reader and interpreted by the interpretation mechanism, the data access eliminator, in the form of a light, magnetic field, or bias eliminates access to the information.
