Abstract
With the emergence of biometricbased authentication systems in realworld applications template protection in biometrics is a significant issue to be considered in the recent years This paper presents two feature set computation algorithms namely nearest neighbor feature set NNFS and Delaunay triangle feature set DTFS for a fingerprint sample Further the match scores obtained from these algorithms are fused using weighted sum rule and Toperators Tnorms and Tconorms The experimental evaluation done on FVC 2002 databases confirms the credibility of fusion method compared to each individual algorithm used for fusing The EER obtained for proposed method is 0 0059 and 393 for FVC 2002 DB1 DB2 and DB3 databases respectively This paper also aims to prove the effectiveness of applying Toperators for fusion at score level in fingerprint template protection
