Problems solved by technology

Unlock by password and graphic, the disadvantage is that the unlocking time is too long and the security is not high
Through face and fingerprint recognition, the problem is that face recognition has false unlocking, and the security is not high.
There is a problem that the fingerprint recognition cannot be unlocked when the finger is injured

[0020] see figure 1 , the unlocking methods for the device include:

[0021] Step 11, when the distance between the NFC antenna of the first NFC module of the device in the locked state and the NFC antenna of the second NFC module of the smart bracelet is less than or equal to a predetermined distance threshold, start the first NFC module The read and write circuit;

[0022] Step 12, identifying the NFC information of the smart bracelet through the read-write circuit;

[0023] Step 13, if the identified NFC information matches the unlocking information stored in the device, unlocking the device is released.

[0024] Specifically, the NFC information described in step 12 in the above embodiment is the unlocking password stored in the second NFC module. When the distance between the NFC antenna of the first NFC module and the NFC antenna of the second NFC module is less than or equal to a predetermined distance threshold, the unlock password is transmitted to the first NFC mo...

[0027] see figure 2 , the embodiment of the present invention also provides a kind of equipment, this equipment comprises:

[0028] A storage module 25, configured to store unlocking information;

[0029] The first NFC module 21 is used to communicate wirelessly with the second NFC module 22 of the smart bracelet through a radio frequency antenna to identify the NFC information of the smart bracelet;

[0030] The unlocking module 23 is configured to release the locked state of the device if the identified NFC information matches the unlocked information.

[0031] The specific NFC information is the unlock password stored in the smart bracelet. When the distance between the NFC antenna of the first NFC module 21 and the NFC antenna of the second NFC module 22 is less than or equal to a predetermined distance threshold, the first NFC module 21 and the second NFC module 22 will An induced magnetic field is generated, and at this time the read-write circuit 24 in the first NFC...

Abstract

The invention provides a device unlocking method and a device. Technical problems such as long unlocking time and low safety are solved. The device unlocking method comprises steps that a distance between the NFC antenna of the first NFC module of the device in a locked state and an NFC antenna of a second NFC module of an intelligent wristband is smaller than or equal to a predetermined distance threshold, the reading-writing circuit of the first NFC module is started; the reading-writing circuit is used to identify the NFC information of the intelligent wristband; when the identified the NFC information is matched with the unlocking information of the device, the locking state of the device is unlocked. By adopting the technical scheme provided by the invention, the NFC wristband is used for the fast and safe unlocking of the device, and the safety level of the device is improved, and then fast unlocking operation is realized, and user safety and user experience are greatly improved.

Description

technical field [0001] The present invention relates to the technical field of NFC (Near Field Communication, near field communication), in particular to a device unlocking method and device. Background technique [0002] At present, the security of some smart terminal devices is becoming more and more important. For example, everyone makes mobile payments on mobile phones, uses electronic wallets, and saves important information such as personal photos. Therefore, the unlocking method for smart terminal devices such as mobile phones has become a Important factors that affect user experience. [0003] At present, the unlocking of smart terminal equipment is mainly realized through password unlocking, graphic unlocking, face recognition unlocking and fingerprint recognition unlocking. Unlocking through passwords and graphics, the disadvantage is that the unlocking time is too long and the security is not high. Through face and fingerprint recognition, the problem is that fa...
