ABSTRACT:
A "state of the art" Computer Security Processor (CSP) is disclosed to stop the "hacker" (a person who enjoys computers as a hobby) by making it virtually impossible to "break into" (a term meaning to falsely gain access to) a computer. A processor is disclosed comprising two units, a transmitter and a receiver. The transmitter sends a special code over the telephone line to the receiver which recognizes a correct or a fraudulent code and then allows access to the host computer provided the code is correct. The unit uses special frequencies other than Touch Tone.RTM., and additionally boasts a wide variety of security codes numbering 8.sup.10 power. These codes can be changed as often as desired. The unit is lightweight, small, and has a low power drain, yet is extremely effective. The transmitter is self-contained and fully portable. The receiver uses normal 120 VAC current and is also portable. Both these units can be built in small housings. The unit does not let the caller hear the modem answering tone, so a "hacker" would not even know he had called a computer. The computer is fully isolated from the caller until the CSP/Receiver recognizes a proper code. The unit will prove to be a low cost answer to a high cost problem.
