Embodiment 1

[0046] Such as figure 1What is shown is a schematic flowchart of the unlocking method provided by Embodiment 1 of the present invention. This embodiment provides a method for collecting a dynamic two-dimensional code and unlocking it according to the collected dynamic two-dimensional code. This embodiment is applicable to the application scenario where the unlocking device performs unlocking. The method can be executed by the unlocking device, which can be smart access control or smart door lock, etc.; in the embodiment of the present invention, the unlocking device is used as the execution subject for description. The method specifically includes the following steps:

[0047] S110. Detect the collected current frame displayed by the dynamic two-dimensional code, and obtain a first serial number, a first time stamp, and a first ciphertext;

[0048] The unlocking device can collect the current frame displayed by the dynamic two-dimensional code through infrared scanning. Det...

Embodiment 2

[0087] Such as figure 2 What is shown is a schematic flowchart of the unlocking method provided by Embodiment 2 of the present invention. On the basis of the first embodiment, this embodiment also provides a process of unlocking according to the user information contained in each frame of the dynamic two-dimensional code refreshed by the two-dimensional code image, thereby reducing the time consumption of unlocking. The method specifically includes:

[0088] S201. Detect the collected current frame displayed by the dynamic two-dimensional code, and obtain a first sequence number, a first time stamp, and a first ciphertext;

[0089] The unlocking device can collect the current frame displayed by the dynamic two-dimensional code through infrared scanning. Detecting the collected current frame displayed by the dynamic two-dimensional code, and obtaining the first sequence number, the first time stamp and the first ciphertext contained in the two-dimensional code image of the c...

Embodiment 3

[0128] Such as image 3 Shown is the unlocking device provided by Embodiment 3 of the present invention. On the basis of Embodiment 1 or 2, the embodiment of the present invention also provides an unlocking device 3, which includes:

[0129] The first detection module 301 is used to detect the current frame displayed by the collected dynamic two-dimensional code, and obtain the first serial number, the first time stamp and the first ciphertext; wherein, the dynamic two-dimensional code is generated every time it is refreshed The serial number of the new frame of QR code is updated and includes the timestamp updated according to the current time;

[0130] The first decryption module 302 is configured to obtain a key for decrypting the first ciphertext according to the first time stamp, and decrypt the first ciphertext to obtain user information;

[0131] In an implementation example, before calculating the time difference between the time information corresponding to the firs...

Abstract

This application belongs to the field of intelligent unlocking technology, and provides an unlocking method, device and storage medium for collecting a dynamic two-dimensional code, the method includes detecting the collected current frame displayed by the dynamic two-dimensional code, and obtaining the first serial number , the first time stamp and the first ciphertext; the sequence number of a new frame of the two-dimensional code generated each time the dynamic two-dimensional code is refreshed is updated and includes the time stamp updated according to the current time; the first decryption key is obtained according to the first time stamp After verifying that the user information is legal, when the local time difference is detected to be greater than the preset threshold, re-acquire the current frame displayed by the dynamic two-dimensional code; detect the re-acquired current frame to obtain the second serial number , a second timestamp and a second ciphertext; if the second serial number is different from the first serial number and the user information is verified to be legal, the local time is corrected and unlocked according to the time information corresponding to the second timestamp. The embodiment of the present application solves the problem that the door lock time needs to be corrected online.

Description

technical field [0001] The present invention relates to the technical field of intelligent unlocking, in particular to an unlocking method, device and storage medium. Background technique [0002] In order to improve the security of the residents in the community and the confidentiality of the office building, access control or door locks are usually set at the entrance and exit of the building. And with the development of today's technology, access control or door locks are also upgraded to smart devices. At present, smart access control or door locks on the market mostly use radio frequency card technology, fingerprint technology, facial recognition technology or two-dimensional code recognition technology. Compared with smart door locks or door locks realized by other identification technologies, smart door locks or door locks realized by two-dimensional code recognition technology are cheaper and more convenient to use, and are more widely used. [0003] At present, af...
