Fixed-length asymmetric binary hashing for fingerprint verification through GMM-SVM based representations

作者:

Highlights:

• This study is a step towards a complete secure fingerprint authentication system in which fixed-length binary minutiae templates generated by our framework can be encrypted and matched via homomorphic encryption methods in an encrypted domain.

• A method for converting unordered and varying number of minutiae into a fixed-length binary string is proposed.

• The framework is based on GMM-SVM fingerprint verification scheme. Novel features are proposed for GMM-SVM since it is not clear what would be the best features to use for fingerprint.

• GMM-SVM feature vectors are binarized using asymmetric locality sensitive hashing.

• Higher recognition accuracies are obtained compared to the state-of-the-art methods.
