Abstract

The invention discloses a fingerprint unlocking method and device, which are used to solve the technical problem of low security of fingerprint unlocking in the prior art. Including: collecting fingerprint information through a fingerprint sensor; comparing the fingerprint information based on the fingerprint feature information to obtain a comparison result; and calculating the comparison result and the first key information through a preset algorithm to obtain the first identity authentication information; A token is generated by a trusted application specified in the TEE of the electronic device when an unlock request is initiated, and is used to indicate the legitimacy of the fingerprint unlock operation initiated in the electronic device; In the specified trusted application, according to the preset verification logic, the legality of the first identity authentication information, the second token and the verification time is verified, and the verification result is obtained; wherein, the second token is the first token passed through the REE. Enter the token of the specified trusted application; when the verification result is correct, unlock 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...
