Problems solved by technology

Since the collector cannot collect, store, and display fingerprint information at will, the validity and integrity of the fingerprint entry cannot be guaranteed when the fingerprint is entered, resulting in a decrease in the success rate of fingerprint comparison in the subsequent use process.

Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with accompanying drawing:

[0018] According to the defects existing in existing fingerprint collectors, the fingerprint collector of the present invention includes sensors, processors, display screens, etc., and the specific structural block diagram is as follows: figure 1 Shown:

[0019] Fingerprint sensor: convert finger fingerprints into image signals that can be recognized by the main control MCU;

[0020] Main control MCU: the main control chip, reads and processes the image signal of the fingerprint sensor, and controls the display at the same time;

[0021] Power management module: control the system power supply to ensure the normal operation of the system while reducing power consumption;

[0022] Display screen: display the relevant information of fingerprint entry.

[0023] Fingerprint entry process:

[0024] (1) When there is no fingerprint entry, the display shows a solid color bac...

Abstract

The invention relates to a fingerprint input method based on grids. The method includes the following steps: when no fingerprint input exists, a power-supply management module cuts off a main-control-MCU power supply; when a fingerprint sensor detects a fingerprint, firstly the main-control MCU is powered on; after the main-control MCU is powered on, a fingerprint image is read; the main-control MCU judges the position and contact point of a finger on the sensor according to the obtained fingerprint image; when different grids are contacted and turned over, a background image displayed by a display screen is a false fingerprint pattern or other instruction patterns used for prompting a user to adjust a finger press position; and after a complete fingerprint image is obtained, the main-control MCU completes an input process. The fingerprint input method based on the grids has the following effects: through adoption of the method, validity and convenience of fingerprint input are ensured; fingerprint input and display are performed synchronously; the position a fingerprint is indicated directly; and efficiency of fingerprint input and comparison is improved.

Description

technical field [0001] The invention relates to the fields of time attendance access control, a fingerprint collector and mobile security payment, in particular to a grid-based fingerprint entry method. Background technique [0002] With the development of society, fingerprints, as each person's unique biological characteristics, are more and more applied to various fields of life, including education, finance, e-commerce, access control, etc. Even ID cards have begun to store personal fingerprint information . Therefore, the application of fingerprint collectors is becoming more and more widespread, but on the other hand, fingerprints are protected by law as personal privacy, and fingerprint information cannot be stored, entered, transmitted, and displayed without the consent of the individual. This has just caused relatively big difficulty to fingerprint collection. [0003] At present, most fingerprint collectors on the market collect fingerprint images multiple times, ...
