Abstract:
1. A fingerprint biometric security method, comprising: deriving, with a computer system, a sample first feature set from a biometric sample, wherein the sample first feature set comprises spatially dependent features including at least one of minutia points and ridge spacing; orienting the sample first feature set to a standardized orientation based on the spatially dependent features; comparing the sample first feature set to a plurality of enrollment first feature sets at the standardized orientation, wherein the enrollment first feature sets are derived from corresponding enrollment biometric templates; determining a single most relevant enrollment biometric template by selecting the enrollment first feature set which most favorably compares to the sample first feature set; deriving a sample second feature set from the biometric sample, wherein the sample second feature set comprises pattern dependent features including at least one of minutia types, ridge flow angles, minutia direction, and ridge patterns; and comparing the sample second feature set to an enrollment second feature set at the standardized orientation, wherein the enrollment second feature set is derived from the most relevant enrollment biometric template, and wherein the sample first feature set is independent of the sample second feature set.
