[0081] Such as figure 2 As shown, based on the above-mentioned mobile terminal hardware structure, an embodiment of the identification device for fingerprint unlocking of the present invention is proposed. Specifically, the identification device for fingerprint unlocking provided by the present invention includes: an acquisition module 21, a comparison module 22, a judgment module 23 and an unlocking module. Module 24, where,

[0082] Obtaining module 21, for obtaining the fingerprint information that the user inputs on the terminal control screen;

[0083] In this embodiment, when fingerprint information is obtained, it is specifically realized through infrared sensor technology. Specifically, the infrared sensor is set under the touch screen of the terminal, and an infrared emitter emits an infrared light signal to the touch screen of the terminal. When the user performs a touch operation on the terminal touch screen, the infrared light signal will be reflected, and the in...

[0117] Please refer to Figure 4 , Figure 4 It is a schematic composition diagram of an identification device for fingerprint unlocking provided by the second embodiment of the present invention. The identification device for fingerprint unlocking specifically includes: an input-output (IO) bus 41, a main controller 42, a RAM 43, a memory 44 and sensor 45; wherein,

[0118] The input-output (IO) bus 41 is respectively connected to other components (main controller 42, memory 43, memory 44) of the terminal to which it belongs, and provides transmission lines for other components.

[0119] The master controller 42 generally controls the overall operation of the server to which it belongs. For example, the main controller 42 performs operations such as calculation and confirmation. Wherein, the main controller 42 may be a central processing unit (CPU). In this embodiment, the sensor 45 is used to obtain the fingerprint information input by the user on the terminal control sc...

[0135] Please refer to Figure 5 , Figure 5 It is a flowchart of an identification method for fingerprint unlocking provided by the third embodiment of the present invention, including:

[0136] S501. Obtain fingerprint information input by the user on the terminal control screen;

[0137] In this embodiment, the acquisition of fingerprint information can be achieved through infrared sensor technology. Specifically, the infrared sensor is set under the touch screen of the terminal, and an infrared transmitter emits an infrared light signal to the touch screen of the terminal. When the user performs a touch operation on the terminal touch screen, the infrared light signal will be reflected, and the infrared receiver receives the reflected infrared light signal, and analyzes the infrared light signal to obtain the user's fingerprint information.

[0138] In practical applications, the fingerprint information includes the fingerprint feature and the first contact area correspo...

Abstract

The invention provides a fingerprint unlocking identification apparatus and method, and a mobile terminal. The method comprises the steps of comparing obtained fingerprint information input by a user with pre-stored first fingerprint information; determining a corresponding effective contact area; then judging whether the effective contact area is greater than a fingerprint contact area threshold or not; and if yes, performing fingerprint unlocking on a touch screen of the terminal according to the fingerprint information. Whether the touch screen needs to be unlocked or not is determined in a manner of comparing fingerprint features and the effective contact area, so that the problem of false unlocking by the user due to false touch of the touch screen is effectively avoided and the usage experience of the user is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminal control, and more specifically, to an identification device and method for fingerprint unlocking. Background technique [0002] At present, with the continuous development of terminal control technology, handheld devices are becoming more and more popular, and more and more attention has been paid to the security and privacy of handheld mobile devices with man-machine interface. Therefore, in order to solve this problem, the fingerprint unlocking function is set in the existing terminals. [0003] Before using the fingerprint unlocking function, the fingerprint must be collected first and entered into the fingerprint database of the terminal. When the user unlocks the polar fingerprint, he only needs to enter the fingerprint again to compare and match with the fingerprint in the database. However, in practical applications, the screen is often accidentally touched. It is always o...
