Abstract:
A method of registering biometric information of an individual comprising the steps of:a) providing a first biometric information sample from a biometric source of the individual to a biometric input device in communication with a host processor;b) using the host processor, registering the first biometric information sample with a first template to produce a first registration value;c) when the first registration value is within predetermined limits, identifying the individual;d) when the first registration value is within other predetermined limits, providing a current biometric information sample from a different biometric source of the individual to a biometric input device in communication with the host processor;e) using the host processor, registering the current biometric information sample with a second template to produce a current registration value;f) when the first registration value relates to a security levels below a predetermined threshold value and a combination of at least the first registration value and the current registration value relates to a security level above a same predetermined threshold, identifying the individual, wherein the first registration value when taken in isolation, if the individual were authorised or identified, would result in a security level below a predetermined minimum allowable security level; andg) when the first registration value and the current registration value are within second other predetermined limits, repeating steps (d) through (g).
