Abstract
A method of registering biometric data is disclosed wherein a registration profile is formed of those templates that have a likelihood of registering with the biometric data that is within predetermined limits. The profile is then compared against one or more other profiles to determine an individual most likely to have said profile. That individual is then identified. Optionally, the profile comparison is used in conjunction with a individual registration values formed by comparison between the biometric data and stored templates.
Claims12
A method of identifying an individual comprising the steps of:
- a) receiving a biometric information sample from a biometric information source of the individual;
- b) characterising the biometric information sample;
- c) comparing the characterised biometric information sample against some of a plurality of stored templates to determine a registration profile comprising indicators of a plurality of templates that match the characterised biometric information sample within predetermined limits;
- d) comparing the registration profile against at least a stored registration profile to determine an identification associated with a registration profile similar to the determined registration profile;
- and,
- e) identifying the individual when the associated registration profile is similar with the determined registration profile within a first predetermined limit.
