Biometric Key
First Claim
1. A biometric key which has an interface or electrical connection to a receptor body which functions as an external power source, a biometric sensor, said biometric key including a central processing unit, a nonvolatile memory unit incorporating a database of authorised biometric signatures along with associated firmware required for comparison between data received from the biometric sensor and to provide acceptance or rejection of said data upon electrical connection to said receptor body whereby a signal is sent to a facility accessible by the biometric key advising of said acceptance or rejection characterized in that during use an authorized biometric signature is not transferred to any external computer or processor.

Abstract
A biometric key (10) which has an interface or electrical connection to a receptor body (11) which functions as an external power source a biometric sensor, a CPU, a nonvolatile memory unit incorporating a database of authorised biometric signatures or biocodes along with associated firmware required for comparison between data received from the biometric sensor and to provide acceptance or rejection of said data upon electrical connection to the receptor body (11) whereby a signal is sent to a facility (12, 13, 15, 16, 17) accessible by the key (10) advising of said acceptance or rejection.

2. A process for providing access to a facility which includes the steps of:
-
providing connection between a biometric key which incorporates a biometric sensor and a receptor body which provides electric power to the key while simultaneously activating the biometric sensor; (ii) establishing a security code in relation to communications between the biometric key and a server; (iii) comparing a biocode received from the biometric sensor with a database located in the biometric key to determine whether said biocode is located in said database and thus corresponds to an authorised biometric signature; and (iv) upon a match and/or no match being made between said data and said database in relation to said authorised biometric signature forwarding a signal to the facility advising of acceptance or rejection of said data in the form of a YES/NO message in regard to providing access to the facility whereby during steps (i), (ii), (iii) and (iv) said authorized biometric signature is not transferred to any external computer or processor. - View Dependent Claims (3, 4, 5, 15)
