The following further describes the content of the application by describing the embodiments with reference to the attached drawings.
The present embodiment provides an infectious disease tracking method for preventing a user from leaking, as shown in fig. 1 and 3, the method including:
s10, the terminal device broadcasts the first device information corresponding to the terminal device at preset time intervals and receives the second device information sent by the external device.
Specifically, the terminal device is a mobile terminal with a broadcasting function, such as a smart phone, a tablet computer, and the like. It is understood that the terminal device is configured with a broadcasting module, and may broadcast its own first device information through the outside of the broadcasting module. The broadcasting module may be a bluetooth module, an NFC module, or the like. In addition, the terminal device may broadcast its own first device information and may receive second device information broadcast by an external device, where the external device is also a mobile terminal having a broadcast function, such as a smart phone and a tablet computer. In one implementation, the external device is configured with a broadcast module, the broadcast module configured in the external device is the same as the broadcast module configured in the terminal device, for example, both the terminal device and the external device are configured with bluetooth modules, and the terminal device broadcasts first device information corresponding to the terminal device through the bluetooth module and receives second device information sent by the external device through the bluetooth module corresponding to the terminal device through the bluetooth module.
Further, the first device information is used to reflect a motion trajectory of the device, and a position where the terminal device stays may be determined based on the first device information, where the first device information includes position information and time information, the position information is used to reflect a geographical position where the terminal device is located when the broadcast is sent, and the time information is used to reflect a sending time of the broadcast. Therefore, the broadcasting, by the terminal device, the first device information corresponding to the terminal device at preset time intervals specifically includes:
the method comprises the steps that the terminal equipment obtains position information of the terminal equipment at intervals of preset time and obtaining time corresponding to the position information;
the terminal device generates random data, and generates the first device information based on the random data, the location information, and the acquisition time.
Specifically, the location information is location information of a geographical location where the terminal device is located at the time of obtaining the location information, and the obtaining time is system time when the location information is obtained. The position information can be determined by a GPS configured by the terminal equipment, and the position information can be latitude and longitude; the acquisition time may be determined by a system time of the terminal device, and the acquisition time may be in accuracy to seconds. In addition, the random data is used to indicate 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 piece of the first device information can reflect state information of a user corresponding to the terminal device at one time. For example, if the terminal device transmits 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 is also the same as the second device information C.
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 any 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, location information > as an example, assuming that the device data is 352458, the acquisition time is 2020-01-1510:30:10, and the location information is longitude 20.54333 and latitude 12.44455, the first device information is <352458,2020-01-1510:30:10, longitude 20.54333, 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 only includes 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, by the terminal device, the random data 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 storage capacity;
and the terminal equipment generates the random data according to the equipment data.
Specifically, the device data is device data corresponding to the obtaining time, that is, when the position information of the terminal device is obtained, the device data of the terminal device is obtained. The device data comprises a cpu temperature, a cpu frequency, a residual memory and a residual memory space, 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 size of the memory which is not used by the terminal equipment during the acquisition time, and the residual memory is the size of the memory which is not used by the terminal equipment during the acquisition 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 may be arranged according to a preset rule to form random data, where the preset rule may arrange the cpu temperature, the cpu frequency, the remaining memory and the remaining memory to obtain any arrangement order. Certainly, in practical applications, since the cpu temperature, the cpu frequency, the remaining memory, and the remaining memory are all numerical values, the obtained cpu temperature, the cpu frequency, the remaining memory, and the remaining memory are respectively split by taking a number as a unit 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 random data, or the plurality of numbers are arranged in a descending order to obtain random data.
In an implementation manner of this embodiment, the second device information is sent by an external device, where a generation manner of the second device information is the same as a generation manner of the first device information, and when a terminal device corresponding to the second device information is taken as a 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. Therefore, the second device information also comprises random data, position information and acquisition time, the random data is according to the cpu temperature, the cpu frequency, the residual memory and the residual storage amount, and the generation rule of the random data is the same as that of the random data corresponding to the first device information.
In addition, 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 the first device information broadcast by terminal device a and all the second device information broadcast by terminal device B are different from each other, that is, for any one first device information, any one of the second device information that is the same as the first device information does not exist in all the second device information; similarly, for any second device information, any first device information identical to the second device information does not exist in all the first device information. Therefore, one terminal device can be uniquely determined based on the received device information, so that the problem of matching error is avoided when the second device information stored by the terminal device is matched with the third device information sent by the server, and the infectious disease tracking accuracy is improved.
For example, the following steps are carried out: the first device information broadcasted by the terminal device a includes <352458,2020-01-1510:30:10, longitude 20.54333, latitude 12.44455>, <352008,2020-01-1510: 30:20, longitude 20.54333, latitude 12.44455>, <352118,2020-01-2007: 58:40, longitude 20.54312, latitude 12.44435>, <352228,2020-01-1507: 58:50, longitude 20.5412, latitude 12.44435 >; the second device information broadcast by the terminal device B includes <952458,2020-01-158:30:10, longitude 10.54333, latitude 12.44455>, <952008,2020-01-158: 30:20, longitude 10.54333, latitude 12.44455>, <952118,2020-01-2007: 58:40, longitude 10.54312, latitude 12.44435>, <952228,2020-01-1507: 58:50, longitude 10.5412, latitude 12.44435 >; the first device information sent by the terminal device a is the same as the second device information sent by the terminal device B.
In one embodiment, in order to determine the 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 intensity corresponding to the second equipment information;
the terminal equipment determines distance information between equipment corresponding to the second equipment information and the terminal equipment according to the broadcast signal strength;
and the terminal equipment adds the distance information to the second equipment information to update the second equipment information.
Specifically, the broadcast signal strength is the signal strength of the broadcast signal received by the terminal device, and the signal strength distance increases and 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. Therefore, after the signal intensity is obtained, the distance information corresponding to the signal intensity is determined 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 larger the distance value. After receiving the second device information sent by the external device, the terminal device of this embodiment determines the distance information between the terminal device and the external device based on the second device information, and adds the distance information to the second device information, so that the terminal device stores the distance information, and thus when the subsequent third device information is successfully matched, it can further determine whether the user corresponding to the terminal device is a contacter according to the distance information in the second device information successfully matched with the third device information, and thus, the accuracy of determining the contacter can be improved.
And S20, when the terminal device receives third device information sent by the server, the terminal device matches the second device information stored by the terminal device with the received third device information, wherein the third device information is device information generated by the terminal device corresponding to the sick person.
Specifically, the third device information is distributed to the terminal device by the server, and the third device information is the device information produced by the terminal device corresponding to the patient. It can be understood that the third device information is generated for a terminal device and uploaded to the server, and a user corresponding to the terminal device generating the third device information is a patient. Therefore, the second device information is generated in the same manner as the first device information, and for example, when the first device information generated by the terminal device is uploaded to the server and the first device information is downloaded to the other terminal device through the server, the first device information is the 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 and 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 from which the distance information is removed is the same as the third device information. In practical applications, the third device information may be multiple, the second device information may also be multiple, and the matching of the second device information and the third device information means: 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 the second equipment information with each piece of third equipment information; and when one of the plurality of pieces of second device information is successfully matched, judging that the piece of second device information is successfully matched, and when one piece of second device information is successfully matched, judging that the piece of second device information is matched with the piece of third device information.
In one implementation, since the third device information is uploaded to a server by a terminal device, the method further includes:
the method comprises the steps that terminal equipment receives an uploading instruction and obtains first equipment information corresponding to the uploading instruction;
and the terminal equipment uploads all the acquired first equipment information to the server.
Specifically, the upload instruction may be input by a user, sent by an external device, or automatically triggered by the terminal device based on a preset condition. The uploading instruction is used for triggering the terminal device to upload the first device information stored by the terminal device to the server, that is, after the terminal device generates and broadcasts the first device information, the terminal device also stores the first device information so as to upload the first device information to the server after receiving the uploading instruction.
The uploading instruction can 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 and the processing amount of the servers can be reduced. In addition, when the user corresponding to the terminal device is not diagnosed as a patient, the terminal device may clean the first device information, which is stored by the terminal device and meets the preset condition, at every preset time, where the preset condition is that a time interval between the acquisition time and the cleaning time corresponding to the first device information reaches a preset threshold, and the preset threshold is preset, for example, 14 days, 21 days, and the like.
In one implementation, as shown in fig. 3, the receiving, by the terminal device, an upload instruction, and acquiring first device information corresponding to the upload instruction specifically include:
the method comprises the steps that terminal equipment receives an uploading instruction and obtains a time interval corresponding to the uploading instruction;
the terminal equipment selects target equipment information from 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 acquired all target equipment information as first equipment information corresponding to the uploading instruction.
Specifically, the time interval may be a time period, after the upload instruction is acquired, the start time corresponding to the upload instruction and the end time corresponding to the upload instruction may be acquired, and the time period between the start time and the end time is taken as the time interval corresponding to the upload instruction. For example, the starting time of the upload instruction is 1/31/2020, the ending time of the upload instruction is 2/3/2020, and the time interval is 1/31/2020 to 2/3/2020. After the time interval is determined, the terminal device screens the first device information stored in the terminal device based on the time interval to remove the first device information of which the acquisition time does not belong to the time interval, so that the first device information needing to be uploaded is determined by self, the first device information of which part of position information needs to be kept secret is prevented from being uploaded, and the user information safety is further improved.
For example, the following steps are carried out: the patient is frontier defense and stationed on the spot guard alone, and the patient has vacated for 5 days recently because the first device information contains the position information, so that the terminal device corresponding to the patient can only upload the first device information corresponding to the vacation 5 days when reporting the first device information, namely, the vacation 5 days are taken as the time interval corresponding to the uploading instruction, thereby avoiding the geographic position information during the working period from being leaked, and improving the safety of the user information.
In an implementation manner of this embodiment, after the terminal device uploads all the acquired first device information to the server, the method further includes:
and determining the passing areas corresponding to all the acquired first equipment information through the server, and distributing all the received first equipment information to the terminal equipment in the passing areas.
Specifically, the server receives all the first device information uploaded by the terminal device, and respectively acquires the position information carried by each first device information, and based on the position information, the passing areas corresponding to all the first device information can be determined, so that the passing areas of the patient can be determined. In addition, when the server receives the first device information sent by the plurality of terminal devices at the same time, the server determines a passing area based on all the first device information corresponding to the plurality of terminal devices, wherein the passing area comprises user passing areas corresponding to the terminal devices. It can be understood that the server does not need to determine the terminal device that uploads the first device information, and then forms the passing area based on receiving all the first device information, and distributes the first device information to the determined passing area, so that the server improves the security of the user information without acquiring the user information.
For example, the following steps are carried out: for example, in a period of 8 to 9 am 2020-01-20, two diagnosed patients in a certain area have their respective corresponding first device information reported by their respective corresponding terminal devices, where the first device information reported by the patient a by its corresponding terminal device a includes:
