Fingerprint authentication based on fuzzy extractor in the mobile device

摘要

Bio-cryptography is the combination of biometrics and cryptography that is a new security technology. For the fuzzy of fingerprint, fuzzy extractor that is a good model to protect the biometric data and can reliably extract almost the same random keys R from the closest input. however, many experiments about fuzzy extractors base on computer, we implement an application for fingerprint authentication in mobile devices based on the fuzzy extractor, the help data we need to store is in the capacity of the mobile extern storage. Unlike previous work, the construction of the input in secure sketch is very simple and uses ISO IEC 19794-2 standard minutia data. Most importantly, the scheme can be more secure to protect the biometric template.
