A biometric security system is disclosed. The system includes a client security system configured to make a request for access to an application module. The application module is configured to receive the request and respond by sending an instruction to the authentication module to initiate an authentication session. The authentication module is configured to receive the instruction and respond by generating a session packet that is transferred to the client security system. The client security system is further configured to generate an authorization packet that is returned to the authentication module after being encrypted utilizing information contained in the session packet.
