A fingerprint entry verification method and device

Abstract

The embodiment of the invention discloses a fingerprint input verification method and device. The method comprises the following steps that: a fingerprint input application sends a verification request to a fingerprint TA (Trusted Application), wherein the verification request carries a challenge factor; when the challenge factor of the fingerprint TA is successful, a verification token is generated, and the verification token is transferred to the fingerprint input application; the fingerprint input application receives the verification token and sends a fingerprint input request to the fingerprint TA, wherein the fingerprint input request comprises the verification token; the fingerprint TA receives the fingerprint input request, and a fingerprint input mode is entered when the verification token is successfully verified. The embodiment of the invention discloses the corresponding fingerprint input verification device. The embodiment of the invention is favorable for improving the safety of a mobile terminal fingerprint input verification process.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a fingerprint entry verification method and device. Background technique [0002] With the popularization and application of smart phones, smart phones can support more and more applications, and their functions are becoming more and more powerful. Smart phones are developing in the direction of diversification and personalization, and become an indispensable electronic product in users' lives.

Problems solved by technology

[0003] At present, the Android operating system OS of mobile terminals includes Android M OS and Android L OS. Fingerprint-related services work in two systems: Android operating system and Trust Execution Environment (TEE) OS. Among them, Android M OS sets There is a standard fingerprint service. The fingerprint entry verification process based on Android M OS is generally that the fingerprint entry application passes the password to the gatekeeper service in TEE OS through the gatekeeperd service, and the gatekeeper service performs password verification. After the password verification is successful, it returns to Android. M OS has a verification token, but there is no fingerprint related service in android L OS, and it does not support the fingerprint entry verification process based on Android M OS. The fingerprint entry verification process based on Android L OS is generally required by fingerprint entry applications. Input the pattern password or digital password, and complete the password verification process in Android L OS, but due to the openness of the Android OS platform, the security of completing the password verification process in Android L OS is relatively low, that is, based on Android L OS The fingerprint entry verification process is difficult to achieve the security based on the fingerprint entry verification process in Android M OS, and it is difficult to meet the actual application requirements
