Fingerprint identification method and fingerprint identification device

Abstract

The invention provides a fingerprint identification method and a fingerprint identification device. The fingerprint identification method comprises steps that when detection on an operator in a fingerprint identification area is detected, the image of the fingerprint identification area is acquired; whether the operator leaves the fingerprint identification area is determined; when the operator does not leave the fingerprint identification area, the image is matched with the preset fingerprint image; when the matching fails, whether the operation on the fingerprint identification area is a misoperation is determined; when the operation on the fingerprint identification area is not the misoperation, a fingerprint identification failure information is transmitted to a server. The FRR accuracy is improved, and therefore the FRR is used to reflect the performance of the fingerprint identification chip really.

Description

technical field [0001] Embodiments of the present invention relate to the electronic field, and in particular, to a fingerprint identification method and device. Background technique [0002] At present, more and more mobile phone manufacturers use big data to analyze the performance of various mobile phone software modules in the actual use of mobile phones by users, and use the final analysis results of big data as important indicators for evaluating the excellent performance of various mobile phone peripherals. [0003] Mobile phone manufacturers can collect the number of successful and failed fingerprint identifications of a large number of users within a certain period of time, and report the big data, and then analyze the big data to obtain the False Rejection Rate (FRR) index of each fingerprint chip, according to FRR Determine the performance of different fingerprint chips. [0004] However, in actual use, apart from the possibility that the user uses an unregistere...

AI Technical Summary

Problems solved by technology

[0004] However, in actual use, apart from the possibility that the user uses an unregistered finger for identification and the performance of the fingerprint chip itself, the fingerprint identification failure may be caused by the user's misoperation.

Fingerprint identification failure caused by user misoperation has nothing to do with the performance of the fingerprint chip

Due to the fact that the user's misoperation is counted when calculating the FRR in the existing technology, the accuracy of the FRR is low, and it cannot truly reflect the performance of the fingerprint chip.
