Abstract

A tokenless security system and method for preventing unauthorized access to one or more secured computer systems is shown. The security system and method are principally based on a correlative comparison of a unique biometric sample, such as a finger print or voice recording, gathered directly from the person of an unknown user with an authenticated unique biometric sample of the same type obtained from each authorized user. The security system and method may be integrated with and dedicated to a single computer system, or may be configured as a non-dedicated, stand-alone entity capable of and intended to perform security functions simultaneously for more than one computer system. Further, the stand alone configuration can be networked to act as a full or partial intermediary between a secured computer system and its authorized users, or may be interactive solely with and act as a consultant to the computer systems. The security system and method further contemplate the use of personal codes to confirm identifications determined from biometric comparisons, and the use of one or more variants in the personal identification code for alerting authorities in the event of coerced acces…
