Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 is a diagram provided for the description of an epidemiological investigation support system 100 according to an embodiment of the present invention, and FIG. 2 is provided for a description of the configuration of an epidemiological investigation support system 100 according to an embodiment of the present invention 3 is a diagram provided to explain the configuration of the epidemiological investigation support server 110 according to an embodiment of the present invention.

The epidemiological investigation support system 100 according to the present embodiment automatically extracts the movement of the confirmed patient with high accuracy based on information such as the confirmed person's entry/exit records, medical institution usage history, mobile communication information and card transaction history, and It is possible to automatically extract the movement-based expected infection network and automatically predict the infection risk area.

In addition, the epidemiological investigation support system 100 compares and verifies the interview information (statement) of the confirmed person and the confirmed person's movement, and when the missing movement line is identified in the confirmed person's interview information, information such as mobile communication information and card transaction history Based on this, the missing movement can be automatically identified and reflected in the infection risk area.

To this end, the epidemiological investigation support system 100 may include an epidemiological investigation support server 110 and an epidemiological investigation support platform 120 .

The epidemiological investigation support server 110 provides information on the confirmed patient to the authority approver 20 such as the National Police Agency and the Credit Association when the information on the confirmed patient is requested from the information requester 10 such as a government agency such as the Virus Infection Control Headquarters or a local government. After requesting permission for approval and collecting the confirmed patient information, the collected confirmed patient information can be analyzed to extract the confirmed patient's movement information.

Specifically, the epidemiological investigation support server 110, when the right to provide information on the confirmed patient of a specific confirmed person is approved, through the epidemiological investigation support platform 120, the location data of the base station-based mobile terminal, which is the result of the mobile terminal's base station inquiry, and the card It is possible to acquire transaction details, immigration records, medical institution usage history, and the like, and extract movement route information including the movement route and real-time location information of the confirmed patient based on the acquired information.

In addition, the epidemiological investigation support server 110 may extract the final movement information by comparing and verifying the interview information of the confirmed patient and the movement information when the interview information is obtained.

Here, the interview information for the confirmed patient includes the contents of a statement secured through an interview on the movement of the confirmed person. ) can be compared and verified by comparing the location information of the base station-based mobile terminal with the location data of the base station-based mobile terminal, and determining whether there is a transaction history of the confirmed patient card at the visited base.

The epidemiological investigation support server 110, as a result of comparative verification, if there is no missing visiting base, confirms the previously extracted movement route information as the final movement route information, and if there is a missing visiting base, the missing visit base or omission The final movement information can be extracted by reflecting the area around the visited base.

Also, when the final movement information is extracted, the epidemiological investigation support server 110 may predict an infection risk area or extract infection network information based on the extracted final movement information.

To this end, the epidemiological investigation support server 110 may include a communication unit 111 , a storage unit 112 , and a processor 113 .

The communication unit 111 performs communication with the terminals of the information requester 10, the authority approver 20, the mobile communication company 30, the card company 40 and the epidemiological investigator 50, and to the epidemiological investigation support platform 120 It means a communication means that can be connected, and the storage unit 112 is a storage medium that stores programs and data necessary for the processor 113 to operate.

The processor 113 is provided to process all matters of the epidemiological investigation support server 110 .

Specifically, the processor 113, when the right to provide information on the confirmed patient of a specific confirmed patient is approved, through the epidemiological investigation support platform 120, the location data of the base station-based mobile terminal, which is the result of the mobile terminal's base station inquiry, card transaction details, immigration It is possible to acquire records, medical institution usage history, and the like, and extract movement route information including the movement route and real-time location information of the confirmed patient based on the acquired information.

In addition, as a result of comparing and verifying the interview information with the confirmed patient and the movement route information, if there is a visit base corresponding to the missing movement route, the processor 113 designates the patient as a confirmed patient of interest, and records the patient's entry/exit records, medical institution usage history, and movement. Information that is the basis of the missing movement line among communication information and card transaction details can be matched and reflected in the final movement line information.

Specifically, when predicting the infection risk area, the processor 113 expands the range of the infection risk area relatively wider than the range of the general confirmed person based on the final movement information of the confirmed patient of interest, but the missing movement line matched with the final movement information The extension range can be determined according to the information that is the basis of the

For example, if the information that is the basis of the missing movement line is card transaction details, the processor 113 extracts a list of expected visit bases where the probability of a visit of a confirmed patient of interest is greater than or equal to a threshold according to the service type of the card transaction base, and , it is possible to expand the range of the infection risk area of the confirmed patient of interest to be relatively wider than the range of the general confirmed patient based on the extracted list of expected visitation points.

An expected visitation point means a restaurant, entertainment establishment, lodging establishment, multi-use facility, medical facility, etc. in a nearby area that provides the same or similar service types to the missing card transaction base.

Specifically, the processor 113 compares the address information of the expected visit base with the base station inquiry result of the mobile terminal of the confirmed patient of interest, extracts the visit suspected base where the probability of the visit of the confirmed patient of interest is greater than or equal to a threshold, and when the suspected visit base is extracted , it is possible to ensure that the extracted suspicious visit point is included in the scope of the infection risk area.

In this case, the processor 113 may use the deep learning learning model to calculate a visit expected base greater than or equal to a threshold from the missing card transaction base, or extract a suspected visit base where the probability of a visit of a confirmed patient of interest is greater than or equal to a threshold.

For another example, if the information that is the basis of the missing movement line is mobile communication information including the base station inquiry result of the mobile terminal of the confirmed patient of interest, the processor 113 may collect images collected in an area matching the base station inquiry result. When the information is analyzed and a person who is presumed to be the same person as the confirmed patient of interest is detected, all areas matching the base station inquiry results of the mobile terminal of the interested confirmed person for a preset period can be included in the infection risk area.

In addition, the processor 113, as a result of analyzing the image information collected in the area matching the base station inquiry result, if a person estimated to be the same as the confirmed patient of interest is not detected, the cash receipt details of the confirmed patient of interest are additionally added to the National Tax Service. By making a request and verifying whether a cash receipt is used in an area matching the base station inquiry result, it is possible to determine whether an infection risk area in an area matching the base station inquiry result is included.

In addition, when extracting infection network information, the processor 113 separates and manages the final movement information of the confirmed patient of interest from the final movement information of the general confirmed patient, selects only the final movement information of the interested confirmed patients, and selects a base for suspected or expected visit It can be used as information on high-precision infection route identification and infection prevention measures in infection-risk areas.

When the authority to provide information is approved, the epidemiological investigation support platform 120 provides at least one of the confirmed patient's entry/exit records, medical institution usage history, mobile communication information and card transaction details through government agencies or mobile communication companies 30 and card companies 40, etc. It is possible to collect information on confirmed cases that includes one.

Through this, the movement of the confirmed patient is automatically extracted with high accuracy based on information such as the confirmed person’s entry/exit records, medical institution usage history, mobile communication information and card transaction history, and the expected infection network based on the movement route of the confirmed person is automatically extracted and infected. The risk area can be predicted automatically, and the interview information (statement) of the confirmed person is compared and verified, and when the missing movement line is identified in the interview information of the confirmed person, based on information such as mobile communication information and card transaction history, The missing movement lines can be automatically identified and reflected in the infection risk area.
