Fingerprint unlocking method and apparatus

Abstract

The invention discloses a fingerprint unlocking method and apparatus, which is used for solving the technical problem of low fingerprint unlocking security in the prior art. The method comprises the steps of collecting fingerprint information through a fingerprint sensor; comparing the fingerprint information based on fingerprint feature information to obtain a comparison result; calculating the comparison result and first key information through a preset algorithm to obtain first identity authentication information, wherein a first token is generated by a trusted application specified in a TEE of an electronic device during initiation of an unlocking request, and is used for indicating the legality of initiating fingerprint unlocking operation in the electronic device; if the comparison result represents that the comparison succeeds, performing legality verification on the first identity authentication information, a second token and verification time according to preset verificationlogic in the specified trusted application, thereby obtaining a verification result, wherein the second token is a token generated after the first token is transmitted into the specified trusted application through the REE; and when the verification result is correct, unlocking the electronic device.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a fingerprint unlocking method and device. Background technique [0002] With the continuous development of electronic technology, various portable devices are becoming more and more common in people's daily life, but the accompanying security issues are also more and more people's attention. [0003] For example, the most common mobile phone in life usually needs to be unlocked before use. At present, it is commonly used to unlock by entering a password, but a safer way is to unlock by scanning a fingerprint. [0004] However, in the existing fingerprint unlocking process, the collection of fingerprint images and the comparison of fingerprint features are all completed in a secure environment (Trusted Execution Environment, TEE), and the security of fingerprint unlocking data in this process can be guaranteed by TEE. However, when the result of fingerprint comparison is ret...
