Method of gathering biometric information

Claim 1

Claim 12

A method of registering biometric information of an individual comprising the steps of: a) providing a first biometric information sample, S 1 , 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, R 1 ; c) when the first registration value, R 1 , is within predetermined limits, identifying the individual; d) when the first registration value, R 1 , is within other predetermined limits, providing a current biometric information sample, S n , from a different biometric source of the individual to a biometric input device in communication with the host processor, where n is of the sequence 1, 2, 3, 4, 5, . . . and n=1 for the first sample and the first registration value associated therewith; e) using the host processor, registering the current biometric information sample with a second template to produce a current registration value, R n ; f) when the first (n-1) registration value relates to a security levels below a predetermined threshold value and a combination of the n registration values relates to a security level above a same predetermined threshold, providing an indication, 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 and wherein the first n-1 registration values when taken as a group, if the individual were authorised or identified, would result in a security level below a predetermined minimum allowable security level; and g) when the first n-1 registration values are within second other predetermined limits, repeating steps (d) through (g).

Claim 13

A method of registering biometric information of an individual comprising the steps of: a) providing a first biometric information sample, S 1 , 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, R 1 ; c) when the first registration value, R 1 , is within predetermined limits, identifying the individual; d) when the first registration value, R 1 , is within other predetermined limits, providing a current biometric information sample, S n , from a different biometric source of the individual to a biometric input device in communication with the host processor, where n is of the sequence 1, 2, 3, 4, 5, . . . and n=1 for the first sample and the first registration value associated therewith; e) using the host processor, registering the current biometric information sample with a second template to produce a current registration value, R n ; f) when the first (n-1) registration value relates to a security levels below a predetermined threshold value and a combination of the n registration values relates to a security level above a same predetermined threshold, providing an indication, 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 and wherein the first n-1 registration values when taken as a group, if the individual were authorised or identified, would result in a security level below a predetermined minimum allowable security level; and g) when the first n-1 registration values are within second other predetermined limits, repeating steps (d) through (g).

Claim 20

A method of registering biometric information of an individual in dependence upon stored templates of biometric information comprising the steps of: a) providing an indication of the individual's identity; b) providing biometric information from a known biometric information source of the individual to a host processor; c) registering the biometric information against a template of biometric information from the same source to determine a registration value using the host processor; d) determining if a point having coordinates in an n-dimensional probability distribution, n having an integer value greater than 1, and having coordinates corresponding to the determined registration values falls within an n-dimensional probability range determined in dependence upon a predetermined false acceptance rate corresponding to a security level above a predetermined threshold wherein a point having co-ordinates in an (n-1)-dimensional probability distribution corresponding to n-1 of the registration values relates to a security level below the predetermined threshold; e) identifying the individual when the point falls within the n-dimensional probability range corresponding to the predetermined false acceptance rate; and, f) repeating steps (b) through (f) when the point falls within a second other n-dimensional probability range.

Claim 21
