Method of locking/unlocking computer screen based on NFC terminal

Abstract

The invention discloses a method of locking / unlocking computer screen based on NFC terminal, comprising the following steps: 101) connecting an NFC reader; 102) setting up a local server; 103) binding an NFC terminal; 104) accessing information configured by a user; 105) establishing a cloud server; and 106) initiating the locking / unlocking of screen. According to the invention, the method has following advantages: 1) NFC terminal used as a key to locking / unlocking a PC screen; when it is used to unlock, all a user needs to do is put the NFC terminal close to a computer NFC recognizer; with it, the screen becomes unlocked. 2) extra layers of security protection to make up loopholes facing computer safety and convenient operations; 3) availability of emergency mode for more secure, more convenient identity identification and computer unlocking; 4) using an active protection mode for the system, and based on used scenes, the protection is set to be automatic, hidden in a bottom layer seldom felt by the user, so that protection becomes silent.

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 an NFC terminal. Background technique [0002] When using a personal computer at present, often encounter the situation that needs to leave temporarily. Generally, users will leave directly without locking the screen. At this time, computer data is most likely to be stolen or destroyed, resulting in personal or company privacy and confidential disclosure; some users will use Windows or other related software and hardware methods, Lock screen.

[0004] Using a software solution: 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 settings are too simple, they are easy to be cracked; if they are too complicated, the user's memory cost is high, and it is easy to forget;

[0005] Using hardware as a solution: Most of them cannot make reasonable use of stock assets and delay users' existing habits, and the cost of using and learning is huge;

[0006] There is only one layer of locking protection, which cannot meet the needs of users for higher security
