Interoperable Protected Fingerprint Minutiae Templates
MetadataShow full item record
With the increasing use of biometric enabled systems, a large amount of biometric systems, sensors, feature formats and matching algorithms have been developed and various template protection methods have been proposed in the literature to enhance the user privacy of biometric enabled systems. The issue of interoperability among different biometric systems has to be concerned. In this project, a fingerprint template protection method named RIME is proposed. It enables interoperability among fingerprint authentication/verification systems that use ISO minutiae template. The RIME method extracts features from minutiae triplets and transforms the features using random projection. In this thesis, the accuracy, irreversibility and unlinkability of RIME are tested and evaluated. The application of RIME under two factor authentication scenario is also discussed.
