A privacy protection and authentication method for fingerprint biometrics

pick 　 want ：

In recent years , More and more intelligent terminals and information systems have integrated biometric technology , And in Finance 、 Widely used in security and other fields . Once the biometric information of users is leaked , It will seriously threaten the vital interests of users . Relying on Fuzzy extraction technology 、 Error correction algorithm and secure hash algorithm , A privacy protection and authentication method of fingerprint biometrics is proposed . In this method , The fingerprint image is not saved in the fingerprint registration stage 、 Details, features and other original information , Only the auxiliary data generated by the error correction coding algorithm and the secure hash algorithm are retained , So as to achieve the purpose of privacy protection . When authenticating , Through the auxiliary data and error correction operation, the image acquisition error is removed and the secure hash operation ciphertext comparison is carried out , Complete user identification .

In recent years , With the wide application of biometric recognition technology , People are increasingly worried about the safety of their own biometrics . Whatever the occasion , As long as you provide your own biometric information , This biometric information has the risk of being copied and stolen . and , Generally speaking, human biological characteristics will not change , Once leaked, it cannot be modified or reset like a password . When the same biometric information is applied to multiple information systems , The disclosure of biometric information in one system will affect the security of other systems .2020 year 10 month , China Academy of communications 、 Telecommunication terminal Industry Association 、 China Internet association and other units jointly published 《 Biometric Privacy Protection Research Report 》. The report points out the need to improve China's biometric privacy protection standard system , Accelerate the development of key standards , Establish an evaluation mechanism , Improve protection , At the same time, we need to innovate biometrics on the technical level
