A tokenless identification system and method for authorization of transactions and transmissions. The tokenless system and method are principally based on a correlative comparison of a unique biometrics sample, such as a finger print or voice recording, gathered directly from the person of an unknown user, with an authenticated biometrics sample of the same type obtained and stored previously. The system can be networked to act as a full or partial intermediary between other independent computer systems, or may be the sole computer systems carrying out all necessary executions. The system further contemplates the use of a private code that is returned to the user after the identification has been complete, authenticating and indicating to the user that the computer system was accessed. The identification system and method additionally include emergency notification device to permit an authorized user to alert authorities an access attempt is coerced.
