A weighted score matching algorithm for a multi-modal biometric system based on fingerprint and hand geometry

摘要

This paper presents a multi-modal biometric system implemented using MATLAB language. The systemfused fingerprint and hand geometry at matching score level by applying a proposed modified weightedsum rule. The fingerprint system was tested using five FVC databases and the hand geometry system wastested using COEP database. Hence, the multi-modal system was tested by merging each FVC databasewith COEP database. The experimental results show significant improvement in the multi-modal systemwith an average EER of 3.27%; while it is 8.86% and 8.89% for fingerprint and hand geometry systems,respectively.
