Method for locking or unlocking computer screen based on fingerprints

Abstract

The invention discloses a method for locking or unlocking a computer screen based on fingerprints. The method comprises the following steps of establishing a local server, extracting fingerprint information, obtaining user settings, establishing a cloud server and enabling screen to be locked or unlocked. The method for locking or unlocking the computer screen based on the fingerprints has the following advantages that the fingerprints serve as a key for locking or unlocking the screen of a personal computer, security is achieved, and the cost is low; multiple layers of secondary validation user protection and an emergency mode are added for providing a more secure and convenient unlocking technology and identity authentication method; an active system protection mode is adopted; according to a use scene, protection is set to be automatically hidden at the bottom layer which cannot be sensed by a user, and soundless protection is achieved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for locking / unlocking a computer screen based on a fingerprint. Background technique [0002] Fingerprint (FingerPrint): Refers to the uneven lines on the front skin of the end of a human finger. The lines are arranged regularly to form different grain patterns. The starting point, ending point, joint point and bifurcation point of the ridge are called the minutiae of the fingerprint. Individual fingerprints vary in patterns, breakpoints and intersections, are unique, and remain unchanged throughout life. [0003] Fingerprint Identification Technology (Fingerprint Identification Technology): It is a biometric identification technology that reads the fingerprint image through the imaging device, then extracts the characteristic data of the fingerprint with computer identification software, and finally obtains the identification result through a matching ide...

AI Technical Summary

Problems solved by technology

[0005] You must manually enter the password or draw an unlock pattern to unlock the screen, which is troublesome to operate

Moreover, if the password and lock pattern are set too simple, it is easy to be cracked; if the password is set too complicated, not only the memory cost is high, but it is also easy to forget;

[0006] There is only one layer of locking protection, and users who cannot meet higher security requirements can achieve more secure data protection;

[0007] Using Bluetooth, IC card and other devices to bind and unlock, it is often encountered that the device is forgotten, lost, stolen, etc.
