Method of gathering biometric information

Claim 1

A method of registering biometric information of an individual comprising the steps of: a) providing a biometric information sample from each of a plurality of different biometric sources of the same individual to at least one biometric input device in communication with a host processor; b) associating each provided biometric information sample with a biometric source; c) using the processor, registering each biometric information sample against a template associated with the associated biometric source; d) determining a plurality of registration values in dependence upon the results of step (c), each registration value from the plurality of registration values relating to a different provided biometric information sample; and, e) when some of the determined registration values relate to security levels below a predetermined threshold value and a combination of the plurality of registration values relates to a security level above a same predetermined threshold, performing one of authorising and identifying the individual in dependence upon the plurality of determined registration values, wherein a single biometric information sample with a determined registration value below the predetermined threshold 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.

Claim 2

A method of registering biometric information of an individual comprising the steps of: a) providing a biometric information sample from each of a plurality of different biometric sources of the same individual to at least one biometric input device in communication with a host processor; b) associating each provided biometric information sample with a biometric source; c) using the processor, registering each biometric information sample against a template associated with the associated biometric source; d) determining a plurality of registration values in dependence upon the results of step (c), each registration value from the plurality of registration values relating to a different provided biometric information sample; and, e) when some of the determined registration values relate to security levels below a predetermined threshold value and a combination of the plurality of registration values relates to a security level above a same predetermined threshold, performing one of authorising and identifying the individual in dependence upon the plurality of determined registration values, wherein a single biometric information sample with a determined registration value below the predetermined threshold 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.

Claim 6

A system for registering biometric information of an individual comprising: a) means for providing a biometric information sample from each of a plurality of biometric sources of the same individual to at least one biometric input device in communication with a host processor; b) means for associating each biometric information sample provided with a biometric source of the individual; c) means for using the processor, registering each biometric information sample against a template associated with the associated biometric source and a same individual; d) means for determining registration values in dependence upon the results of step (c); and, e) means for when some of the determined registration values relate to security levels below a predetermined threshold value and a combination of the plurality of registration values relates to a security level above a same predetermined threshold, performing one of authorising and identifying the individual in dependence upon the plurality of determined registration values, wherein a single biometric information sample with a determined registration value below the predetermined threshold 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.

Claim 7

A system for registering biometric information of an individual comprising: a) means for providing a biometric information sample from each of a plurality of biometric sources of the same individual to at least one biometric input device in communication with a host processor; b) means for associating each biometric information sample provided with a biometric source of the individual; c) means for using the processor, registering each biometric information sample against a template associated with the associated biometric source and a same individual; d) means for determining registration values in dependence upon the results of step (c); and, e) means for when some of the determined registration values relate to security levels below a predetermined threshold value and a combination of the plurality of registration values relates to a security level above a same predetermined threshold, performing one of authorising and identifying the individual in dependence upon the plurality of determined registration values, wherein a single biometric information sample with a determined registration value below the predetermined threshold 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.

Claim 16

A method of registering biometric information of an individual in dependence upon stored templates of biometric information comprising the steps of: a) providing a set of parameters comprising a set of biometric information sources to a host processor; b) in dependence upon the set of biometric information sources, providing biometric information samples from a same individual from at least some of the sources to at least a biometric input device in communication with the host processor; c) using the host processor, registering the biometric information samples against some of the templates associated with a same individual to produce a set of registration values; d) when some of the determined registration values relate to security levels below a predetermined threshold value and a combination of the plurality of registration values relates to a security level above a same predetermined threshold, determining if a point in a multidimensional space and having coordinates corresponding substantially to the registration values falls within a multidimensional range determined in dependence upon a predetermined false acceptance rate; and, e) identifying the individual when the point falls within the multidimensional range corresponding to the acceptable false acceptance rate.

Claim 17

A method of registering biometric information of an individual in dependence upon stored templates of biometric information comprising the steps of: a) providing a set of parameters comprising a set of biometric information sources to a host processor; b) in dependence upon the set of biometric information sources, providing biometric information samples from a same individual from at least some of the sources to at least a biometric input device in communication with the host processor; c) using the host processor, registering the biometric information samples against some of the templates associated with a same individual to produce a set of registration values; d) when some of the determined registration values relate to security levels below a predetermined threshold value and a combination of the plurality of registration values relates to a security level above a same predetermined threshold, determining if a point in a multidimensional space and having coordinates corresponding substantially to the registration values falls within a multidimensional range determined in dependence upon a predetermined false acceptance rate; and, e) identifying the individual when the point falls within the multidimensional range corresponding to the acceptable false acceptance rate.
