摘要
This paper presents a novel algorithm of fingerprint encryption which transforms fingerprint minutiae and performs matching in the transformed form If an encrypted template is compromised it can be cancelled by choosing just another transformed template In our algorithm a circular region is constructed around each minutia and non-invertible transformation is applied to all regions but only transformed regions are stored in the database The proposed algorithm improves the accuracy of verification compared to related fuzzy vault systems Experimental results sho
