Abstract
A timed erasure mechanism can be used with portable computer-readable media to ensure automatic erasure of secure information, minimizing the security risks in using such media to store and transport passwords, codes, keys and similar private setup information. The portable computer-readable media can comprise volatile memory and a timed erasure mechanism in the form of a power supply and discharging circuitry that discharges the power supply after a predetermined amount of time. Alternatively, the portable computer-readable media can comprise nonvolatile memory and a timed erasure mechanism in the form of a digital time and erasure algorithms that are initiated after a predetermined amount of time. Furthermore, such portable computer-readable media can comprise a container that bears unique physical properties that can alert users to the volatile nature of the media.
