Balancing is the key: Performing finger vein template protection using fuzzy commitment

We propose a novel vein extraction technique adapted to template protection and use it to apply a fuzzy commitment scheme. We construct dedicated error correcting codes that enable us to maintain a good accuracy after template protection. In a second application, we offer to overcome the alignment issues when comparing two vein templates by performing this step outside of the protection scheme. Different implementations are proposed to explore trade-offs between False Rejection Rate, False Acceptance Rate, comparison time and security. All approaches are tested on the recent database of University of Twente from ICB 2013. Our biometric performances are close to state of the art approaches whilst bringing security with the template protection scheme.
