A fingerprint entry control method and device

Abstract

The embodiment of the invention discloses a fingerprint entry control method and device. The method includes: the fingerprint TA detects a touch operation for the fingerprint sensor sensor, and the fingerprint TA is in the fingerprint entry mode; when the fingerprint TA detects the first touch operation for the fingerprint sensor, generates a TouchDown message, and notifies the TouchDown message to the entry fingerprint application ; The fingerprint entry application receives the TouchDown message, and when it detects that the duration of the first touch operation is greater than or equal to the first preset threshold, outputs a first prompt message for prompting the user to lift the finger. The embodiments of the present invention are beneficial to improve the fingerprint entry function of the mobile terminal, and improve the operation efficiency of the fingerprint entry of the mobile terminal.

Description

Problems solved by technology

[0003] At present, most mobile terminals of the Android system implement fingerprint-related functions based on the fingerprint architecture of Android M. The fingerprint-related functions include the fingerprint entry function. During the implementation of the fingerprint entry function, the user generally needs to enter the fingerprint image multiple times to generate the user-specific fingerprint template. Each time a fingerprint is entered, the mobile terminal first detects that the finger touches the fingerprint sensor sensor, then collects the fingerprint image, matches the image, and distributes the message. Since the fingerprint trusted application (TrustApplication, TA) only calls back the fingerprint message to the fingerprint service For users with fingerprints, there is very little information that can be perceived, especially for new users who are relatively unfamiliar with the fingerprint entry function, new users may not leave the fingerprint sensor for a long time after first contacting the fingerprint sensor, or leave the sensor for a long time The fingerprint sensor has not been touched again, and the mobile terminal does not have an accurate event detection and reminder mechanism for such situations, making it difficult for new users to complete the fingerprint entry function smoothly, and even cause troubles for users
