Abstract
An apparatus and method for protecting data stored on a disk of a computer. The invention provides data access protection using a security software program, a hardware key, and a user password to permit access to the hard or floppy disk used in the computer. The program stores the hardware key code and password on the disk and encrypts disk partition data, and without using the correct hardware key and password, the partition data is unreadable. An encryption algorithm operates at all times and prevents unauthorized entry once the computer is turned off. A microcircuit key provides a unique stored code when energized, and a key connector is provided to use the key. The computer connector may also be adapted to permit coupling of an output device to the computer. Versions are disclosed for use with ports having bidirectional and unidirectional input and output lines.
