Claim:
1. A method for two-directional biometric matching, comprising: receiving a first biometric record and a second biometric record for matching, wherein the first biometric record is a sample biometric record provided from a biometric sensor and the second biometric record is a stored biometric record; performing a first matching process using an asymmetric matching algorithm to match the first biometric record to the second biometric record to obtain a first matching outcome, wherein the asymmetric matching algorithm comprises a layered series of algorithms comprising at least one trigger point, wherein a strong similarity result at the trigger point activates a short-cut branch through the layered series of algorithms; performing a second matching process using the asymmetric matching algorithm of the first matching process to match the second biometric record to the first biometric record to obtain a second matching outcome; and comparing the first matching outcome and the second matching outcome to determine if there is a difference in outcome.
