Intelligent application based three-dimensional code unlocking method

Abstract

The invention discloses an intelligent application based three-dimensional code unlocking method which comprises the following steps: performing deep learning of the information of multiple three-dimensional code patterns collected at different angles and different light rays to obtain an accurate three-dimensional code comparison threshold and a weight parameter; in an unlocking process, verifying the user identity, by a three-dimensional code scanning device, according to internal permission setting; verifying a three-dimensional code according to the three-dimensional comparison threshold and the weight parameter; verifying a password and a sequence number (or sequence number only) of a secret key area of the three-dimensional code; upon success of the three levels of verification, executing the unlocking. Moreover, when a variable secrete key and a variable sequence number are both arranged in the secrete key area, an algorithm of changing the sequence number is generally an add-subtract algorithm of adding 1 or subtracting 1, and quick unlocking can be ensured; the secrete key does not need to be changed each time; through regular change, the safety can be further improved, the unlocking time is shortened, and good experience feeling is provided for the user.

Description

technical field [0001] The invention relates to an intelligent application-based three-dimensional code unlocking method. Background technique [0002] With the development of modern electronic technology, lock and key devices in the modern sense are not limited to traditional purely mechanical locks. In recent years, with the rise of two-dimensional codes, two-dimensional code lock and key devices have also appeared. The two-dimensional code lock and key device is that the user uses the two-dimensional code as a key or an auxiliary key, and the two-dimensional code lock and key device scans the two-dimensional code displayed on the mobile terminal to unlock when unlocking. Compared with traditional purely mechanical locks, the two-dimensional code lock and key device avoids the trouble that users always need to carry the key with them, and at the same time, the unlocking process is more convenient. However, the current two-dimensional code lock and key device uses a two-di...

Problems solved by technology

The introduction of pixels causes a change in the brightness of the QR code, distorts the binarization threshold, and increases the probability of decoding errors

The second challenge is to use the entire area of ​​the QR code to optimize the visual problem

QR codes have limited error correction capability, so it is not possible to simply replace the QR code module with image pixels

In this method, although the reading quality of the three-dimensional code is improved, the decoding accuracy rate is improved, and the visual perception is optimized, there is still a risk of loss or leakage after being copied, which brings great security risks
