Secure data storage system for a computer wherein a heat transfer apparatus cools a data storage unit in a fireproof safe in absence of a fire and ceases transfer in the event of a fire

摘要

A secure data storage system for a computer has a data storage system with a data interface to the computer mounted on a heat sink structure within a fireproof enclosure. A heat transfer system connected to the heat sink structure and to a wall of the fireproof enclosure transfers heat from the heat sink structure to outside the fireproof enclosure. A thermostat controller mounted outside the fireproof enclosure, upon detecting a temperature indicating of a fire, causes the heat transfer system to cease transferring heat from inside the fireproof enclosure to outside the fireproof enclosure and blocks passage of heat from outside the fireproof enclosure to inside the fireproof enclosure via the heat transfer system. Both passive and active heat transfer systems are disclosed. In another aspect of the invention, security for entered passwords is provided by diverting password keystrokes from a keyboard to a special controller, bypassing the keyboard controller. In one embodiment the special controller is also a read/write controller simulating an interface to a local hard disk, but in reality transferring data to be stored via a data link to the data storage unit in the fireproof enclosure.
