Problems solved by technology

The information broadcast by a bluetooth mesh device could indeed be exploited by a potentially malicious mobile phone program, leading to unintentional location privacy violations, or even targeting invisible bluetooth devices to infiltrate user devices, resulting in intrusion data carriers of user devices and steal information
[0004] Due to the difficulty in guaranteeing protocol security in computer networks, there is a greater security risk of data theft through Bluetooth connections, which may lead to the acquisition of private information of the investigated equipment other than epidemic prevention and control, resulting in information leakage

Embodiment 1

[0056] This embodiment provides a method for obtaining close contact personnel information, which is executed by a device with a Bluetooth device name scanning function, and the device is installed with a close contact APP for implementing a solution. Such as figure 1 ,include:

[0057] S101. Scan and acquire the Bluetooth device names of one or more closely connected devices;

[0058]In this step and the following steps, the device scans for one or more other close-connected devices within the distance via Bluetooth. Wherein, the close-connected device refers to the device whose distance to the device with the Bluetooth device name scanning function is less than a certain value. The Bluetooth device name refers to the Bluetooth address. In this process, the device with the Bluetooth device name scanning function is regarded as the master device, and other close-connected devices are described as slave devices. During scanning, the slave device broadcasts its own Bluetooth...

Embodiment 2

[0100] The mobile phone device in this embodiment can also perform a write operation on the name of the close-connected device after each scan of the surrounding close-connected devices, and at the same time, after the close-connected device sends the name of the Bluetooth device every time, it will be modified and updated to realize the close-connected information. Change in time. Such as image 3 , including the following steps:

[0101] S201. Scan and obtain the Bluetooth device names of one or more closely connected devices;

[0102] S202. Decode the Bluetooth device name using a preset codec model;

[0103] S203. Use the decoded Bluetooth device name as the close connection information of the close connection device.

[0104] S204. Generate a write operation signal based on the decoded Bluetooth device name;

[0105] S205. Send the write operation signal to the device, so that the device modifies the Bluetooth device name based on the write operation signal.

[0106] I...

Embodiment 3

[0114] In an alternative embodiment, in the above steps, when the device acts as the master device, it may scan the surrounding close-connected devices every preset time interval. When the device is a slave device, such as Figure 5 , perform the following steps:

[0115] S301. Encode the close connection information using a preset codec model;

[0116] This step forms a new state vector by dynamically encoding the close connection data. Specifically: the device saves the close connection information in the flash and reads the name from the flash. Specifically, there will be a Generic Access service in the Nordic protocol stack by default. , the service is a general attribute specification service, which provides a way for the device to determine information (including the name change of its own device). The mobile phone accesses the service and saves the new name in flash. Save the address and length of the name stored in flash, take it out from user_config.h, and put it in...

Abstract

The invention provides a method for acquiring information of a close contact person, which is executed by equipment with a Bluetooth equipment name scanning function and comprises the following steps of: scanning and acquiring Bluetooth equipment names of one or more close contact equipment; decoding the name of the Bluetooth equipment by using a preset coding and decoding model; and taking the decoded Bluetooth device name as the close connection information of the close contact equipment. According to the invention, the close connection information is coded into the name of the Bluetooth equipment, so that the close connection equipment can be obtained only by scanning the name without connecting the Bluetooth, and the information is coded into digits and then attached to the Bluetooth name, so that the exchange and acquisition of useful information between mobile phone equipment can be directly carried out without establishing connection. Due to the fact that protocol security in a computer network is difficult to guarantee, the potential safety hazard that Bluetooth connection transmission data is stolen is large. Only the name is identified and stored in a mode of not establishing connection, so that the problem of protocol stealing can be directly avoided, and the equipment security is improved.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, relate to a method, device, server, and storage medium for obtaining information on close contacts. Background technique [0002] In the existing COVID-19 epidemic prevention policy, it is usually necessary to obtain the information of close contacts of confirmed and suspected cases. The usual method is to investigate the flow of people through the investigation of cameras and other images based on the offline movement trajectories of confirmed and suspected cases. , It is more labor-intensive. [0003] Some manufacturers query personnel information through Bluetooth connection information on the mobile terminal. The information broadcast by a bluetooth mesh device could indeed be exploited by a potentially malicious mobile phone program, leading to unintentional location privacy violations, or even targeting invisible bluetooth devices to infiltrate user device...
