Description

Technical Field

[0001] The invention belongs to the field of electronic information technology, and in particular relates to a double-person authentication method for a Bluetooth mobile phone lock control system. Background Art

[0002] With the development of society, the state has tightened the control over hazardous chemicals. According to the different control levels, it can be divided into a single-person single-lock management mode (i.e. single-person mode) and a two-person double-lock management mode (i.e. two-person mode), and requires one or two people to sign and record the ledger to leave a trace. The highest control mode is the two-person mode, in which two people are required to unlock the lock to achieve the purpose of knowing the unlocking and supervising each other.

[0003] With the development of smart phones, more and more applications are being made of smart unlocking using mobile phone Bluetooth signals. One of the most famous patents is CN103318299A "An electric vehicle control system and its operation method", which is used to unlock the vehicle by scanning the code with a mobile phone. Its main feature is a QR code recognizer consisting of a micro camera, a graphic decoder, a memory and a QR code comparator. When the user takes a QR code image with a micro camera, the QR code comparator will compare the image data with the QR code data in the memory. If the comparison signal is consistent, the controller starts the electric vehicle; if the comparison signal is inconsistent, the controller controls the anti-theft alarm to sound the alarm. Mobike also uses wireless signals to connect smart phone applications, cloud servers, and lock controllers. The vehicle identity information is stored in the QR code, and after scanning the code, it is checked in the cloud to decide whether to authorize unlocking.

[0004] However, in existing applications, smartphones and Bluetooth locks are all single phones corresponding to single locks. It is easy to achieve single-person mode, but there is no two-person verification and authorization. It is difficult to achieve the function of two-person unlocking within the authorization range. Existing mobile phone Bluetooth unlocking requires a good environmental communication signal, and in places such as rooms and warehouses where controlled hazardous chemicals are stored, the signal shielding is often strong, and ordinary mobile phone communication may not be applicable. According to relevant laws and regulations, controlled hazardous chemicals must be transported and used by qualified personnel, and the information of relevant authorized personnel must also be bound to the Bluetooth lock control system. The general principle is that only authorized people can open the designated cabinet and record it in time. The existing system does not have these functions. At present, it basically uses the mode of manual record keeping, which is cumbersome, laborious, and easy to tamper with or misremember. Summary of the invention

[0005] In order to overcome the above defects, the present invention provides a two-person authentication method for a Bluetooth mobile phone lock control system, which solves the problem that both a smart phone and a Bluetooth lock correspond to a single mobile phone and a single lock, and it is easy to achieve single-person mode, but it does not achieve two-person verification and authorization. The function of two-person unlocking within the authorization range is difficult to achieve, and currently basically uses a manual record-keeping mode, which is cumbersome, laborious, and easy to be tampered with or misremembered.

The single-person mode can be unlocked by a single person, and the two-person mode requires that two people must authenticate at the same time to unlock, and both modes can automatically record the use of the lock control system. Based on a general smart phone, the personnel and lock information are entered into the information database to achieve the purpose of controlling the scope of authorized personnel and two-person unlocking.

[0022] S202, the mobile phone automatically recognizes the face and the storage cabinet QR code and storage cabinet serial number after taking a photo. The software searches the database for facial features and compares the relevant unlocking authorization. If the storage cabinet and Bluetooth lock are within the unlocking authority, a signal is sent to the software, which is recognized as half successful unlocking;

[0023] S203. Next, authorized personnel No. 1 and authorized personnel No. 2 exchange positions to take photos, and the two photos are taken using the mobile phones of authorized personnel No. 1 and authorized personnel No. 2 respectively. In the same process, if it is recognized that the person in the photo has the permission to unlock the storage cabinet, a signal is sent to the software, which is recognized as half of the unlocking success, so that Bluetooth lock No. 1 and Bluetooth lock No. 2 on storage cabinet No. N are opened.

[0024] As a further solution of the present invention: In S3, the electronic tags of the drugs are classified and identified as follows:
