Device Controller and Method of Enforcing Time Based High Level Data Characteristics

摘要

A device controller interfaced between an electronic processing device and a sector-based data storage device, includes a processor connected to a clock, and a computer memory having a control list stored therein. A control list includes a security feature entry having a high level data characteristic, time data associated with the characteristic, and at least one security response associated with the characteristic. The processor determines, based at least in part on interrogation of the control list and a clock time, the time data of the entry conflicts with the clock time, and executes the at least one security response.
