Key generation from biometrics has been studied intensively in recent years, linking a key with certain biometric enhances the strength of identity authentication. But the state-of-the-art key generation systems are far away from practicality due to low accuracy. The special manner of biometric matching makes a single feature based key generation system difficult to obtain a high recognition accuracy. Integrating more features into key generation system may be a potential solution to improve the system performance. In this paper, we propose a fingerprint based key generation system under the framework of fuzzy extractor by fusing two kinds of features: minutia-based features and image-based features. Three types of sketch, including minutiae based sketch, modified Biocode based sketch, and combined feature based sketch, are constructed to deal with the feature differences. Our system is tested on FVC2002 DB1 and DB2, and the experimental results show that the fusion scheme effectively improves the system performance compared with the systems based only on minutiae or modified Biocode.
