    Abstract: A code-word security system uses a logic module which can receive an account code word (or any other data that is specific to an individual) and a secret code word from an individual for encoding in accordance with a logical combination of such code words altered in accordance with a selectable control word to produce a compiled code word of fixed length. Such compiled code words may be stored and retrieved for comparison with a compiled code word similarly generated during the course of an authorized transaction by such individual, or may be transmitted with coded information and other data pertaining to such authorized individual for logical manipulation.
