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
The present invention relates to field of information security technology, particularly to one based on NFC terminal lock locking/unlocking electricity
The method of brain screen.
Background technology
At present when using PC, it is frequently encountered and needs situation away from keyboard.General user can be straight
Connect and leave, will not screen locking, now, be easiest to occur computer data stolen, destroyed, cause individual or public affairs
Privacy and the secret of department are revealed；Some user can use Windows or other related softwares, hard
Part mode, lock-screen.
But all there are the following problems:
Use software scenario: must manually input password or drafting the unlocking pattern could unlock screen,
Troublesome poeration.And if password and locking pattern arrange excessively simple, are easily cracked；If it is the most complicated,
The memory cost of user is the highest, is also easy to forget；
Hardware is used to make scheme: majority Appropriate application stock assets user of postponing cannot use habit
Used, use learning cost huge；
Only one layer locking protection, it is impossible to meet the demand of user Geng Gao safety.
The involved part technical term of the present invention:
NFC (Near Field Communication, near-field communication): be the radio skill of a kind of short distance high frequency
Art, the compatible equipment in 13.56MHz frequency with 20 cm distance is identified and data exchange.NFC
There is following two mode of operation.
Mode card (Card emulation): this pattern is the most just comparable to one and uses RFID technique
IC-card.Can substitute substantial amounts of IC-card (including the credit card) occasion market swipe the card, mass transit card, gate inhibition
Control, ticket, admission ticket etc..Under this kind of mode, there is a great advantage, that is, card is by non-
The RF territory of contact card reader powers, even if host's equipment (such as mobile phone) does not has electricity to work.
Ad hoc mode (P2P mode): this pattern and infrared ray are similar, can be used for data exchange,
Simply transmission range is shorter, and transmission creates speed, transmission speed the most hurry up, (bluetooth also class low in energy consumption
Like).By two linking of devices possessing NFC function, data point-to-point transmission can be realized, as down-load music,
Exchange picture or synchronizer address book.
Summary of the invention
The present invention is directed to the defect of prior art, it is provided that a kind of based on NFC terminal lock locking/unlocking computer screen
The method of curtain, can effectively solve the problem that the problem that above-mentioned prior art exists.
A kind of method based on NFC terminal lock locking/unlocking computer screen, comprises the following steps:
