Fingerprint comparison method of intelligent identity authentication channel applied to multi-biometric feature recognition

The invention relates to a fingerprint comparison method of an intelligent identity authentication channel applied to multi-biometric feature recognition. According to the fingerprint comparison method, fingerprint picture data are acquired from a database, are converted into fingerprint feature data and are divided into a plurality of sets, and finally the fingerprint feature data of fingerprints to be compared are compared by the adoption of multithreading. The fingerprint comparison method of the intelligent identity authentication channel applied to multi-biometric feature recognition can improve the fingerprint comparison speed and accuracy; the entire method is implemented in an internal storage, and storage safety risks of hard disk storage are avoided. Under the condition that a remote database can only store fingerprint pictures, the fingerprint comparison method of the intelligent identity authentication channel applied to multi-biometric feature recognition improves the speed of a fingerprint comparison process.
