Abstract
The present invention comprises methods and systems for mitigating distortive effects in biometric samples in a biometric verification system. More specifically, it generates a live template from a live image, and stores the live template as a rolling template, if the live template corresponds to the master template according to predefined criteria. As a result, the system allows the applicant to subsequently access the system if a subsequent live template generated from a subsequent live image of the biometric sample for the applicant corresponds to either the master template or the rolling template according to predefined criteria. Thus, the inventive arrangements accommodate dynamic changes in an applicant's biometric samples.
