Abstract

The proposed invention provides a capacitor-driven protection device for highly security-sensitive data which assures total prevention of access to data in the event of removal of hard drive, e.g. by hostile persons. The proposed invention provides this security by applying a high static charge to the medium in response to unauthorized removal or tampering, with the result that the data and medium are irrecoverably destroyed. Known capture of military aircraft, ships, etc. has likely compromised highly secret or confidential data. This simple, inexpensive device could have easily and effectively prevented this loss to hostile powers. Furthermore, the proposed device is far safer and quicker to use than some other intelligence-destroying mechanisms, including detonation of grenades in a secure drum.

Bee Stinger Hard Drive Security System Based on Capacitor-Driven Complete Assured Destruction (CDCAD)

Direct analogy: to protect its hive, the honeybee stings the intruder, leaving the stinger embedded in the victim. The bee thereby destroys itself by evisceration. The hive has lost a resource, but at least is safe. Comparison: self-destruction of taped instruction medium to covert operatives at beginning of each "Mission Impossible" episode.

* Proposed invention protects critical data from unauthorized access by totally destroying both data and recording medium in the event of attempted theft.

* Any unauthorized removal of appropriately equipped hard drives irrecoverably destroys the recording medium, along with all resident data and programs, thereby thwarting theft and potential loss to competitor.

* Proposed invention contains the loss by canceling out broader damage through data loss to competitor.

* This protection is rendered by triggering the application of a stored electrical charge to the hard drive, of sufficient voltage to completely destroy both data and recording medium, rendering both irrecoverably, permanently unusable.

* The destructive discharge is delivered by an electrolytic capacitor of appropriate rating.
* The capacitor charges as needed anytime the equipped computer is connected to a power source.
* Capacitor characteristically retains its charge long after the machine is disconnected from power source.

* When armed, invention "zaps" the har...
