The application will be further described by the description of embodiments with reference to the accompanying drawings.
The present embodiment provides a method for tracking infectious diseases for preventing user leakage, as shown in fig. 1 and fig. 3, the method includes:
s10, the terminal equipment broadcasts the corresponding first equipment information at intervals of preset time, and receives second equipment information sent by the external equipment.
Specifically, the terminal device is a mobile terminal with a broadcasting function, for example, a smart phone, a tablet computer, and the like. It will be appreciated that the terminal device is configured with a broadcast module and may broadcast its own first device information through the outside of the broadcast module. The broadcasting module may be a bluetooth module, an NFC module, etc. In addition, the terminal device may receive the second device information broadcast by the external device, while broadcasting the first device information of the terminal device, where the external device is also a mobile terminal with a broadcasting function, for example, a smart phone, a tablet computer, and the like. In one implementation manner, the external device is configured with a broadcast module, the broadcast module configured by the external device is the same as the broadcast module configured by the terminal device, for example, both the terminal device and the external device are configured with bluetooth modules, the terminal device broadcasts first device information corresponding to the terminal device through the bluetooth modules, and receives second device information sent by the external device through the bluetooth modules corresponding to the terminal device through the bluetooth modules.
Further, the first device information is used for reflecting the motion trail of the device, a position where the terminal device stays can be determined based on the first device information, the first device information comprises position information and time information, the position information is used for reflecting the geographic position where the terminal device is located when the broadcast is sent, and the time information is used for reflecting the sending time of the broadcast. Thus, the terminal device broadcasts the corresponding first device information per se at preset time intervals specifically including:
the terminal equipment acquires the position information of the terminal equipment per se at preset time intervals and acquires time corresponding to the position information;
the terminal equipment generates random data and generates the first equipment information based on the random data, the position information and the acquisition time.
Specifically, the location information is location information of a geographic location where the terminal device is located at an acquisition time, and the acquisition time is a system time when the location information is acquired. The position information can be determined by a GPS configured by the terminal equipment, and the position information can be longitude and latitude; the acquisition time may be determined by a system time of the terminal device, and the acquisition time may be accurate to seconds. In addition, the random data is used for representing the uniqueness of the first device information, that is, the first device information sent by the terminal device each time is different from each other, so that the uniqueness of the first device information can be ensured, and each first device information can reflect the state information of the corresponding user of the terminal device at one moment. For example, if the terminal device has transmitted the first device information a, the first device information B, and the first device information C, the first device information a is different from the first device information B and the first device information C, and the first device information B and the second device information C are also the same.
Further, the first device information includes random data, location information, and acquisition time, and the first device information is formed by combining the random data, the location information, and the acquisition time in an arbitrary order. For example, the first device information may be < random data, location information, acquisition time >, or < random data, acquisition time, location information >, or the like. Here, taking the first device information as < random data, acquisition time, and location information > for the sake of example, assuming that the device data is 352458, the acquisition time is 2020-01-15:10:30:10, the location information is longitude 20.54333 and latitude 12.44455, then the first device information is <352458, 2020-01-1510:30:10, longitude 20.54333, and latitude 12.44455>. The first device information in this embodiment is determined according to the random data, the location information and the acquisition time, and includes only the location information of the terminal device and the time of the location information, and does not include the user information corresponding to the terminal device, thereby further improving the security of the user information.
In one implementation, the generating random data by the terminal device specifically includes:
The terminal equipment acquires equipment data corresponding to the acquisition time, wherein the equipment data comprises a CPU temperature, a CPU frequency, a residual memory and a residual memory capacity;
and the terminal equipment generates the random data according to the equipment data.
Specifically, the device data is the device data corresponding to the acquisition time, that is, when the location information of the terminal device is acquired, the device data of the terminal device is acquired. The device data comprises a CPU temperature, a CPU frequency, a residual memory and a residual memory, wherein the CPU temperature is the CPU temperature of the terminal device at the acquisition time, and the CPU frequency is the CPU frequency of the terminal device at the acquisition time; the residual memory is the unused memory size of the terminal equipment when acquiring time, and the residual memory is the unused memory size of the terminal equipment when acquiring time.
After the cpu temperature, the cpu frequency, the remaining memory and the remaining memory are obtained, the cpu temperature, the cpu frequency, the remaining memory and the remaining memory can be arranged according to a preset rule to form random data, wherein the preset rule can be used for arranging the cpu temperature, the cpu frequency, the remaining memory and the remaining memory to obtain any arrangement sequence. Of course, in practical application, since the cpu temperature, the cpu frequency, the remaining memory and the remaining memory are all values, the cpu temperature, the cpu frequency, the remaining memory and the remaining memory are respectively split by taking the numbers as units to obtain a plurality of numbers, and then random data is generated according to the obtained plurality of numbers, for example, the plurality of numbers are randomly arranged to generate the random data, or the plurality of numbers are arranged in order from large to small to obtain the random data, or the plurality of numbers are arranged in order from small to obtain the random data, and the like.
In an implementation manner of this embodiment, the second device information is sent by an external device, where a generating manner of the second device information is the same as that of the first device information, and when a terminal device corresponding to the second device information is used as the terminal device, the terminal device corresponding to the first device information is an external device of the terminal device corresponding to the second device information. Thus, the second device information also includes random data, location information, and acquisition time, and the random data is according to the cpu temperature, cpu frequency, remaining memory, and remaining storage, and the generation rule of the random data is the same as the generation rule of the random data corresponding to the first device information.
Further, the information content of the second device information is different from the information content corresponding to the first device information. It can be understood that, as shown in fig. 2, for any two terminal devices, terminal device a and terminal device B, all first device information broadcast by terminal device a and all second device information broadcast by terminal device B are different from each other, i.e., for any one first device information, no second device information identical to the first device information exists in all second device information; similarly, for any piece of second equipment information, any piece of first equipment information which is the same as the second equipment information does not exist in all pieces of first equipment information. Therefore, based on the received equipment information, one terminal equipment can be uniquely determined, so that the problem of matching error is avoided when the second equipment information stored by the terminal equipment is matched with the third equipment information sent by the server, and the accuracy of infectious disease tracking is improved.
Illustrating: the first device information broadcast by terminal device A includes <352458,2020-01-1510:30:10, longitude 20.54333, latitude 12.44455>, <352008,2020-01-15:10:20, longitude 20.54333, latitude 12.44455>, <352118,2020-01-20:07:58:40, longitude 20.54312, latitude 12.44435>, <352228,2020-01-15:07:50, longitude 20.5412, latitude 12.44435>; the second device information broadcast by terminal device B includes <952458,2020-01-158:30:10, longitude 10.54333, latitude 12.44455>, <952008,2020-01-15:8:20, longitude 10.54333, latitude 12.44455>, <952118,2020-01-20:07:58:40, longitude 10.54312, latitude 12.44435>, <952228,2020-01-15:07:50, longitude 10.5412, latitude 12.44435>; the first device information sent by the terminal device a is different from the second device information sent by the terminal device B.
In one embodiment, in order to determine a distance between the terminal device and the external device corresponding to the second device information, after receiving the second device information sent by the external device, the method further includes:
the terminal equipment acquires the broadcast signal strength corresponding to the second equipment information;
the terminal equipment determines the distance information between the equipment corresponding to the second equipment information and the terminal equipment according to the broadcast signal intensity;
The terminal device adds the distance information to the second device information to update the second device information.
Specifically, the broadcast signal strength is the signal strength of the broadcast signal received by the terminal device, and the increase in the signal strength distance decreases, so that the distance between the external device corresponding to the second device information and the terminal device can be calculated based on the signal strength. After the signal intensity is obtained, determining distance information corresponding to the signal intensity according to a signal loss theory, wherein the distance information is the distance between the external equipment corresponding to the second equipment information and the terminal equipment, and the larger the signal intensity is, the smaller the distance value is; conversely, the weaker the signal strength, the smaller the distance value. After receiving second equipment information sent by the external equipment, the terminal equipment determines distance information between the terminal equipment and the external equipment based on the second equipment information, and fills the distance information into the second equipment information, so that the terminal equipment stores the distance information, and when the subsequent third equipment information is successfully matched, whether a user corresponding to the terminal equipment is a contactor or not can be further judged according to the distance information in the second equipment information successfully matched with the third equipment information, and the accuracy of judging the contactor can be improved.
And S20, when the terminal equipment receives the third equipment information sent by the server, the terminal equipment matches the second equipment information stored by the terminal equipment with the received third equipment information, wherein the third equipment information is the equipment information generated by the terminal equipment corresponding to the patient.
Specifically, the third device information is device information produced by the terminal device corresponding to the patient, and the third device information is distributed to the terminal device by the server. It can be understood that the third device information is generated for a terminal device and uploaded to the server, and the user corresponding to the terminal device that generates the third device information is a patient. Thus, the second device information is generated in the same manner as the first device information, for example, when the first device information generated by the terminal device is uploaded to the server, and the server is used to send the first device information to other terminal devices, the first device information is third device information with respect to the other device information.
Further, the third device information includes random data, location information and acquisition time, and the second device information broadcasted by the external device stored in the terminal device includes random data, location information, acquisition time and distance information, so that when the terminal device matches the second device information stored in the terminal device with the received third device information, the distance information in the second device information is removed, and the removed second device information is matched with the third device information. Wherein, the matching refers to whether the second device information and the third device information after the distance information is removed are the same. In practical applications, the number of the third device information may be multiple, and the number of the second device information may also be multiple, where the matching between the second device information and the third device information refers to: for each piece of second equipment information in the plurality of pieces of second equipment information, removing the distance information in the second equipment information and then respectively matching with each piece of third equipment information; and when one piece of second equipment information is successfully matched with the second equipment information, judging that the second equipment information is successfully matched, and when one piece of second equipment information is successfully matched with the third equipment information, judging that the second equipment information matched with the third equipment information is present.
In one implementation, since the third device information is uploaded to the server for the terminal device, the method further includes:
the terminal equipment receives an uploading instruction and acquires first equipment information corresponding to the uploading instruction;
and the terminal equipment uploads all the acquired first equipment information to the server.
Specifically, the uploading instruction may be input by a user, may be sent by an external device, or may be automatically triggered by a terminal device based on a preset condition. The uploading instruction is used for triggering the terminal equipment to upload the first equipment information stored by the terminal equipment to the server, that is, the terminal equipment can store the first equipment information after generating and broadcasting the first equipment information, so that the first equipment information is uploaded to the server after receiving the uploading instruction.
The uploading instruction may be triggered after the user corresponding to the terminal device is diagnosed as the patient, that is, when the user corresponding to the terminal device is not diagnosed as the patient, the terminal device does not need to upload the first device information stored by the terminal device to the server, so that the data transmission amount of the terminal device can be reduced, and the number of processing amounts of the server can be reduced. In addition, when the user corresponding to the terminal device is not diagnosed as a patient, the terminal device may clear the first device information stored by the terminal device per se and meeting a preset condition every preset time, where the preset condition is that a time interval between the acquisition time corresponding to the first device information and the clearing time reaches a preset threshold, and the preset threshold is preset, for example, 14 days, 21 days, and the like.
In one implementation manner, as shown in fig. 3, the terminal device receives an upload instruction, and the obtaining the first device information corresponding to the upload instruction specifically includes:
the terminal equipment receives an uploading instruction and acquires a time interval corresponding to the uploading instruction;
the terminal equipment selects target equipment information from the first equipment information stored in the terminal equipment according to the time interval, wherein the acquisition time carried by the target equipment information is in the time interval;
and the terminal equipment takes the obtained information of all the target equipment as the first equipment information corresponding to the uploading instruction.
