도 1은 본 발명의 일 실시예에 따른 감염병 접촉자 탐지 시스템의 구성을 도시한 도면이다. 본 발명의 실시예에 따른 감염병 접촉자 탐지 시스템은, 사용자 단말들(100-1, 100-2, ..., 100-n)이 감염병 접촉자 탐지 서버(200)와 통신 가능하도록 연결되어 구축된다.1 is a diagram showing the configuration of an infectious disease contact detection system according to an embodiment of the present invention. An infectious disease contact detection system according to an embodiment of the present invention is constructed by connecting user terminals 100-1, 100-2, ..., 100-n to communicate with the infectious disease contact detection server 200.
사용자 단말(100-1, 100-2, ..., 100-n)에는 감염병 확진자 탐지 앱(110-1, 110-2, ..., 110-n)이 설치될 것이 요구된다. 감염병 확진자 탐지 앱(110-1, 110-2, ..., 110-n)은 사용자의 위치정보를 수집하여 감염병 접촉자 탐지 서버(200)로 전송한다.The user terminals 100-1, 100-2, ..., 100-n require that the confirmed infectious disease detection apps 110-1, 110-2, ..., 110-n be installed. The confirmed infectious disease detection apps (110-1, 110-2, ..., 110-n) collect user location information and transmit it to the infectious disease contact detection server 200.
사용자는, 감염병 확진자일 수도 있고, 감염병 미확진자로써 감염병 접촉자와 감염병 미접촉자 중 어느 하나의 상태이다. 본 발명의 실시예에서 탐지하고자 하는 대상은 감염병 접촉자이다.The user may be a confirmed infectious disease person, or a non-confirmed infectious disease person, in a state of either contact with an infectious disease or non-contact with an infectious disease. In an embodiment of the present invention, a target to be detected is an infectious disease contact.
위치정보 수집을 위해, 감염병 확진자 탐지 앱(110-1, 110-2, ..., 110-n)은 GPS 좌표, BLE 비컨, WiFi 핑거프린트 등을 수신한다. 위치정보는, GPS 좌표, BLE 비컨의 경우 BLE ID와 수신 세기, WiFi 핑거프린트의 경우 AP의 ID와 수신 세기가 될 수 있다.To collect location information, the infectious disease detection app (110-1, 110-2, ..., 110-n) receives GPS coordinates, BLE beacon, WiFi fingerprint, etc. The location information may be GPS coordinates, BLE ID and reception strength in the case of a BLE beacon, and AP ID and reception strength in the case of a WiFi fingerprint.
감염병 접촉자 탐지 서버(200)는 사용자 단말들(100-1, 100-2, ..., 100-n)에 의해 수집된 위치정보들을 기반으로 감염병 접촉자를 탐지한다.The infectious disease contact detection server 200 detects an infectious disease contact based on the location information collected by the user terminals 100-1, 100-2, ..., 100-n.
사용자 단말들(100-1, 100-2, ..., 100-n)로부터 감염병 접촉자 탐지 서버(200)로 전달되는 위치정보들 중 개인정보 보호가 요구되는 위치정보는 암호화되어 전달된다.Among the location information transmitted from the user terminals 100-1, 100-2, ..., 100-n to the infectious disease contact detection server 200, location information requiring protection of personal information is encrypted and transmitted.
이 과정에 대해, 이하에서 도 2 내지 도 4를 참조하여 상세히 설명한다. 이하에서, 사용자 단말(100-1, 100-2, ..., 100-n)은 사용자 단말(100)으로 통칭하여 표기할 수 있고, 감염병 확진자 탐지 앱(110-1, 110-2, ..., 110-n)은 감염병 확진자 탐지 앱(110)으로 통칭하여 표기할 수 있다.This process will be described in detail with reference to FIGS. 2 to 4 below. Hereinafter, the user terminals 100-1, 100-2, ..., 100-n may be collectively referred to as the user terminal 100, and the confirmed infectious disease detection app (110-1, 110-2, ..., 110-n) may be collectively referred to as the infectious disease confirmed person detection app 110.
도 2는 본 발명의 다른 실시예에 따른 위치정보 수집 방법의 설명에 제공되는 흐름도이다.2 is a flowchart provided to explain a location information collection method according to another embodiment of the present invention.
사용자들의 위치정보를 수집하기 위해, 먼저 감염병 확진자 탐지 앱(110)을 통해 사용자의 개인정보 보호구역을 설정한다(S310). 개인정보 보호구역은 사용자가 자신의 세부 위치정보를 밝히지 않고 싶어하는 구역을 말한다.In order to collect location information of users, first, a user's personal information protection area is set through the infectious disease confirmed person detection app 110 (S310). A privacy zone is an area where users do not want to reveal their detailed location information.
개인정보 보호구역 설정은 다음의 두 가지 방법으로 가능한데, 그 밖의 다른 방법을 이용하는 것을 배제하지 않는다.Establishment of personal information protection area is possible in the following two ways, but it is not excluded to use other methods.
첫 번째 방법은 지오펜스 기술을 이용하는 것이다. 이는, 도 3에 도시된 바와 같이 사용자가 지정한 지점의 GPS 좌표를 중심으로 일정 반경 내 구역을 개인정보 보호구역인 지오펜스로 지정하는 방법이다. 여기서, 지정 가능한 지오펜스의 개수와 반경은 감염병 관리 당국에 의해 결정되도록 할 수 있지만, 그 밖의 다른 기준에 의할 수도 있으며, 여기에는 사용자의 설정이 포함될 수도 있다.The first method is to use geofence technology. As shown in FIG. 3, this is a method of designating an area within a certain radius centered on the GPS coordinates of a point designated by the user as a geo-fence, which is a personal information protection area. Here, the number and radius of designable geo-fences may be determined by the infectious disease control authority, but may be based on other criteria, and may include user settings.
두 번째 방법은 사용자가 지정한 구역에서 수집되는 WiFi 핑거프린트와 BLE 비컨을 지정하여 개인정보 보호구역으로 설정하는 방법이다. GPS 좌표 측정이 불가능하거나 부정확한 실내 장소를 개인정보 보호구역으로 설정하는 경우에 적합한 방법이다.The second method is to designate the WiFi fingerprint and BLE beacon collected in the user-specified area and set it as a personal information protection area. This method is suitable for cases where GPS coordinate measurement is impossible or an inaccurate indoor place is set as a personal information protection area.
이후, 감염병 확진자 탐지 앱(110)은 위치정보 수집을 시작하는데(S320), 현재 위치가 S310단계에서 설정된 개인정보 보호구역이면(S330-Y), 감염병 확진자 탐지 앱(110)은 사용자의 위치정보로 WiFi 핑거프린트와 BLE 비컨을 수집한다(S340). 즉, 개인정보 보호구역에서 GPS 좌표 수집은 배제된다.Then, the confirmed infectious disease detection app 110 starts collecting location information (S320), and if the current location is a personal information protection area set in step S310 (S330-Y), the infectious disease detection app 110 is the user's WiFi fingerprint and BLE beacon are collected as location information (S340). In other words, the collection of GPS coordinates is excluded in the personal information protection area.
다음, 감염병 확진자 탐지 앱(110)은 수집한 위치정보를 해시 함수 등으로 암호화하고(S350), 암호화된 위치정보를 저장한다(S360). S360단계에서 위치정보 저장은 사용자 단말(100)일 수도 있고 감염병 관리 서버(200)일 수도 있다. 이는 개인정보 보호 정책 상의 문제이다. 전자의 경우 감염병 접촉자 탐지시 감염병 관리 서버(200)가 사용자 단말(100)에 지난 과거의 위치정보들을 요청하여야 한다.Next, the confirmed infectious disease detection app 110 encrypts the collected location information with a hash function (S350) and stores the encrypted location information (S360). In step S360, the location information storage may be the user terminal 100 or the infectious disease management server 200. This is a privacy policy issue. In the former case, when detecting a contact with an infectious disease, the infectious disease management server 200 must request past location information from the user terminal 100 .
반면, 현재 위치가 S310단계에서 설정된 개인정보 보호구역이 아니면(S330-N), 감염병 확진자 탐지 앱(110)은 사용자의 위치정보로 GPS 좌표, WiFi 핑거프린트와 BLE 비컨을 수집한다(S370). 개인정보 보호구역과 달리 GPS 좌표 수집도 포함된다.On the other hand, if the current location is not the personal information protection area set in step S310 (S330-N), the confirmed infectious disease detection app 110 collects GPS coordinates, WiFi fingerprints and BLE beacons as the user's location information (S370) . Unlike privacy zones, GPS coordinates collection is also included.
다음, 감염병 확진자 탐지 앱(110)은 수집한 위치정보를 암호화하지 않고 저장한다(S380). S380단계에서 위치정보 저장 역시 사용자 단말(100)일 수도 있고 감염병 관리 서버(200)일 수도 있다.Next, the confirmed infectious disease detection app 110 stores the collected location information without encryption (S380). In step S380, location information storage may also be the user terminal 100 or the infectious disease management server 200.
도 4는 본 발명의 또 다른 실시예에 따른 감염병 접촉자 탐지 방법의 설명에 제공되는 흐름도이다.4 is a flowchart provided to explain a method for detecting a contact of an infectious disease according to another embodiment of the present invention.
감염병 확진자가 발생하면(S410-Y), 먼저 감염병 관리 서버(200)는 감염병 확진자의 확진일 14일 전부터 현재까지의 위치정보들을 획득한다(S420).When a confirmed infectious disease occurs (S410-Y), the infectious disease management server 200 first acquires location information of the confirmed infectious disease from 14 days before the confirmed date to the present (S420).
다음, 감염병 관리 서버(200)는 S420단계에서 획득된 감염병 확진자의 위치정보들 중 암호화되지 않은 위치정보들을 모두 암호화한다(S430). S430단계에서의 암호화 방식은 감염병 확진자의 암호화된 위치정보들을 암호화한 방법과 동일하다.Next, the infectious disease management server 200 encrypts all unencrypted location information among the location information of the confirmed infectious disease person acquired in step S420 (S430). The encryption method in step S430 is the same as the method of encrypting the encrypted location information of the confirmed infectious disease patient.
그리고, 감염병 관리 서버(200)는 감염병 확진자의 확진일 전 14일 동안에 수집된 사용자의 위치정보들을 획득한다(S440).Then, the infectious disease management server 200 acquires user location information collected during the 14 days prior to the confirmation date of the confirmed infectious disease (S440).
다음, 감염병 관리 서버(200)는 S440단계에서 획득된 사용자의 위치정보들 중 암호화되지 않은 위치정보들을 모두 암호화한다(S450). S450단계에서의 암호화 방식은 사용자의 암호화된 위치정보들을 암호화한 방법과 동일하다.Next, the infectious disease management server 200 encrypts all unencrypted location information among the user's location information acquired in step S440 (S450). The encryption method in step S450 is the same as the method of encrypting the user's encrypted location information.
이후, 감염병 관리 서버(200)는 동일자의 동시간 대에 수집된 암호화된 감염병 확진자의 위치정보들과 암호화된 사용자의 위치정보들을 비교하여, 사용자가 감염병 접촉자인지 판단한다(S460).Thereafter, the infectious disease management server 200 compares the location information of the encrypted confirmed infectious disease person collected at the same time of day with the encrypted location information of the user, and determines whether the user has come into contact with the infectious disease (S460).
S460단계에서 위치정보의 비교는 다음의 방법에 의해 수행될 수 있다.Comparison of location information in step S460 may be performed by the following method.
1) 동일자의 동시간대에, 감염병 확진자의 단말(100)에서 전송된 BLE 비컨이 사용자의 단말(100)에 일정 시간 동안 수신된 경우 또는 반대로 사용자의 단말(100)에서 전송된 BLE 비컨이 감염병 확진자의 단말(100)에 일정 시간 동안 수신된 경우, 사용자를 감염병 접촉자로 판단1) At the same time of day, when the BLE beacon transmitted from the terminal 100 of the confirmed infectious disease is received by the user's terminal 100 for a certain period of time, or conversely, the BLE beacon transmitted from the user's terminal 100 confirms the infectious disease If the user's terminal 100 is received for a certain period of time, the user is judged as a contact with an infectious disease
2) 동일자의 동시간대에, 감염병 확진자의 단말(100)과 사용자의 단말(100)에 동일한 BLE 비컨이 일정 시간 동안 수신된 경우, 사용자를 감염병 접촉자로 판단2) If the same BLE beacon is received by the terminal 100 of the confirmed infectious disease and the terminal 100 of the user for a certain period of time at the same time of the same person, the user is determined as a contact with the infectious disease
3) 동일자의 동시간대에, 감염병 확진자의 단말(100)과 사용자의 단말(100)에 동일한 WiFi 핑거프린트가 일정 시간 동안 수신된 경우, 사용자를 감염병 접촉자로 판단3) When the same WiFi fingerprint is received by the terminal 100 of the confirmed infectious disease and the terminal 100 of the user for a certain period of time at the same time of the same person, the user is determined as a contact with the infectious disease
4) 동일자의 동시간대에, 감염병 확진자의 단말(100)의 GPS 좌표와 사용자의 단말(100)의 GPS 좌표가 일정 시간 동안 동일한 경우, 사용자를 감염병 접촉자로 판단4) If the GPS coordinates of the terminal 100 of the person confirmed with an infectious disease and the GPS coordinates of the terminal 100 of the user are the same for a certain period of time at the same time, the user is determined as a contact with the infectious disease
