Abstract

The invention provides a fingerprint recognition method and a mobile terminal. The method is applied to the mobile terminal which is provided with an embedded security chip and a confidence region module. The method comprises the following steps of: enabling the embedded security chip to acquire a fingerprint image input by a current user when receiving a fingerprint recognition instruction; performing feature extraction on the fingerprint image so as to obtain fingerprint features; sending the fingerprint features to a microprocessor of the embedded security chip and enabling the microprocessor of the embedded security chip to perform data processing and fingerprint recognition on the fingerprint features, so as to obtain a fingerprint recognition result; enabling the embedded security chip to send the fingerprint recognition result to the confidence region module; and enabling the confidence region module to perform digital signature on the fingerprint recognition result, then sending the fingerprint recognition result subjected to digital signature to the mobile terminal, thereby finishing fingerprint recognition. According to the fingerprint recognition method and the mobile terminal, a fingerprint recognition process is maliciously tampered.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a fingerprint identification method and a mobile terminal. Background technique [0002] With the rapid development of the mobile Internet, the trend of mobile payment as an important part of the payment field has become clear. Driven by the wave of mobile payment, the rapid rise of mobile payment not only brings convenience to consumers, but also leaves corresponding security risks. Among them, payment security has undoubtedly become one of the most concerned issues. [0003] As a way of identifying identity in mobile payment, fingerprint payment has been widely used in the field of mobile payment. The technical core of fingerprint payment is fingerprint identification technology, which belongs to biometric identification technology. Because it is not easy to copy, and there is no need to worry about being lost or forgotten, it has a higher security level than ordinar...
