摘要：A method for authenticating an individual by use of fingerprint data thatinvolves two different broad steps. The first step is to obtain a biometrics fingerprintsignature template (“BFST”) for an individual in an enrollment process by selecting a
plurality of bands for the BFST and obtaining a plurality of tracks corresponding to eachof the plurality of bands by use of an enrollment frame of a selected finger of theindividual, wherein the plurality of bands are spatially referenced to the enrollmentframe and can be spatially referenced to a reference barrier. The second step is toauthenticate (or not) a candidate finger against one or more BFST in an authenticationprocess in which a swipe direction and an access code for the individual are selected, aplurality of candidate tracks are obtained from the candidate finger through use of thereference barrier in an authentication unit so that each of the plurality of candidate tracksis spatially referenced so as to be within a corresponding one of the plurality of bands,calculating a similarity index for each of the plurality of candidate tracks and each of theplurality of tracks for the band to which the candidate track corresponds by use of a FastFourier-transform fingerprint algorithm, and multiplying each maximum similarity indexobtained for each of the plurality of candidate tracks to obtain a match index whichindicates a match if it exceeds a preselected threshold.
