Description

Self-quarantine management system for preventing the spread of infectious diseases using hybrid indoor location information and biometrics {SELF-ISOLATION SYSTEM FOR THE EPIDEMIC INFECTED SUSPECT}

The present invention relates to a self-quarantine management system for preventing the spread of infectious diseases using hybrid indoor location information and biometrics.

The present invention relates to a self-quarantine management system for preventing the spread of infectious diseases using hybrid indoor location information and biometrics. , BLE, geomagnetism, barometric pressure, UWB) technology to self-quarantine and information management solution.

From SARS, MERS, swine flu, and corona virus pandemics, the damage to countries around the world is getting serious. In particular, even if secondary to fifth infections occur due to negligence in the management of infected people, suspected infections, or those subject to self-quarantine, the spread of the virus rapidly spreads without even knowing the route of infection. In addition, another damage is expected every year due to the emergence of unpredictable mutated viruses, but there is no clear solution or preventive measure.

The absolute conditions to prevent and prevent the spread of infectious diseases caused by viruses are to block the source from the initial outbreak site and to isolate and manage the infected person promptly.

In fact, in many virus-spreading countries, suspected infections, who are subject to self-quarantine, escape from the quarantine area without permission and spread to secondary and tertiary infections. (Fingerprint, iris, pace, voice, vein) and location information (GPS, WiFi - rssi/rtt, BLE, geomagnetic, barometric pressure, UWB) can be used to manage quarantined subjects.

However, if the location of the quarantined person is confirmed using only the GPS satellite navigation system, it is impossible to check the movement of the quarantined person in the residential complex or apartment. GPS can be easily turned off, making it difficult to check movement. In addition, if the person to be quarantined uses two smartphones or simply leaves the smartphone in the quarantined place and goes out, it becomes difficult to determine the location using only GPS.

Republic of Korea Patent Publication No. 10-2017-0021692, 'A system for tracking the movement path of a person suspected of being infected with an infectious disease and a method for tracking the movement path using the same' is a smart terminal that can generate location information and time information and transmit it to the control center, and a suspected infection or infection confirmation Check the location of suspected or confirmed infection in real time, including the control center server that receives, stores, and displays location information and time information from medical institution terminals and smart terminals that determine the person and deliver unique information such as determination results and phone numbers so that you can manage it. However, since such a system uses only the GPS of the infected person's smartphone to check the location information, there is no countermeasure against this in the case of an infected person leaving the smartphone in the same building or underground space.

The present invention has been devised to solve the above problems, and an object of the present invention is to provide a system for easily monitoring escaping from an isolated space by performing biometric authentication and indoor location confirmation.

An infected person may intentionally leave their smartphone in the quarantine area and go out. To prepare for this, the system sends quarantine confirmation messages to the infected person irregularly, so that the person's biometric information (fingerprint, iris, Face, voice, vein) to authenticate yourself. And when the identification of the infected person is completed through biometric identification, the current location information of the infected person is automatically scanned and the presence or absence of quarantine is checked by matching with the location information of the initially registered quarantine location.

If identification through biometric information or location information matching of the quarantined place fails, re-authentication is requested through a warning sound. Even when a quarantined person leaves the quarantine area without permission within the quarantine period, a warning message is immediately sent to request authentication confirmation. In addition, it is possible to prevent secondary infection by providing the movement path of the quarantined person to nearby general users in real time.

In order to check whether the quarantined person is in the quarantined place, the indoor location information (WiFi-(rssi/rtt), BLE, geomagnetism, barometric pressure, etc.) Through this, it is possible to check the location and track the movement route immediately.

In addition, self-diagnosis questions, follow-up information according to the results, and information on similar infectious diseases are provided so that the general public who is not infected with the virus can self-diagnose and prevent.

Although video treatment is not yet permitted under the Medical Act, in the case of viral infectious diseases, medical staff treats suspected patients through monitors to prevent secondary infection. Additional imaging services can be provided only in countries.

In order to achieve the above object, to provide a self-quarantine management system to prevent the spread of infectious diseases using hybrid indoor location information and biometrics, the system server 11, the quarantined person's terminal 12, and the monitoring server 13 are It is connected through a network and the quarantine terminal 12 includes a biometric recognition module 31, an indoor location information collection module 32, and a GPS 33. The GPS 33 collects the location information of the quarantine terminal 12. Collecting and using a biometric sensor, the biometric module 31 checks whether the quarantined terminal 12 is operated by a registered quarantined person and checks whether it is operated by a registered quarantined person or not, the system server 11 and the indoor location information collection module 32 collects indoor location information collected in the quarantined space of the quarantined person and transmits it to the system server 11, which isolates the quarantined person's information transmitted from the quarantined terminal 12 To store in the child DB 21, the biometric information DB 23 in the quarantine DB 21 stores the quarantined person's biometric information, and the quarantine person location information DB 24 stores the quarantined person's location information and indoor location information. When a biometric information mismatch message comes from the quarantined terminal 12 or the biometric information same determination module 34 determines that the quarantined person is a different person from the registered person, a biometric information inconsistency message is transmitted to the monitoring server 13 and indoor location information When it is determined that the same determination module 35 deviates from the initially registered indoor location, a quarantine site departure message may be transmitted to the monitoring server 13 .

The biometric information may be one or more of a fingerprint, an iris, a retina, a vein, and a face.

The information collected by the indoor location information collection module 32 is sensed by the MAC address, SSID and strength of the WIFI signal, the distance value to the AP measured in the WIFI ??rtt method, information and strength of the Bluetooth device, and the geomagnetic sensor. It may be one or more of information to be detected, information collected by a barometer, information collected by UWB, information sensed by an accelerometer, and information sensed by a gyro sensor.

Wi-Fi may be sensed using signal strength (rssi) like wifi rssi, or may be sensing using wifi-rtt (round trip time). If WIFI-rtt is used, it is possible to measure the distance between the WIFI-access point and the WIFI-recognized peer device.

The indoor location information collection module 32 may additionally collect and accumulate indoor location information of the quarantined person when communicating with the quarantined terminal 12 in addition to the initially collected information.

The indoor location information same determination module 35 may notify the system server 11 when it is determined that the collected indoor location information exceeds a range measured in the same space.

If the MAC address, SSID, and RSSI categories of the WIFI signal are changed more than predetermined, it can be determined that the range measured in the same space is exceeded.

From the information sensed by the accelerometer and the gyro sensor, when the moving direction and the total moving distance of the isolator terminal are out of the isolation space, it can be determined that the range measured in the work space is exceeded.

It further includes a medical institution terminal 15, transmits the infection determination information and the infected person's biometric information to the system server 11, and stores it in the biometric information DB 23 and cross-checks the biometric information sent from the quarantined terminal 12 can make it

A non-isolated user including the self-diagnosis information DB 25 may perform a self-diagnosis using the user terminal 25 , and the self-diagnosed information may be stored in the system server 11 .

Depending on the country, it may not be possible to separately collect and store the biometric information. In this case, the biometric information may be stored and used only in the quarantined terminal 12 .

The invention as described above has the effect of providing a system that can efficiently manage the escape of the quarantined person himself/herself isolated from the quarantine space in order to prevent the spread of infection.

1 to 4 are views showing an embodiment according to the present invention;

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In the system according to the present invention, a user may be an infected person or a suspected infection, and may be different depending on the disease, but may correspond to a person who has been quarantined at home or the like to prevent the spread of infection.

When a person suspected of infection receives a quarantine determination at a hospital or the Korea Centers for Disease Control and Prevention, etc., the app that can use the system according to the present invention is installed on the quarantined terminal 12, and the self-quarantine receives his/her biometric information and basic information on the quarantine terminal ( 12), at this time, the quarantined terminal 12 collects and stores the location information of the quarantined place, and then transmits the quarantined location information to the system server 11 along with the quarantined's biometric information and basic information. . In addition, the medical institution terminal 15 also transmits the information collected to the medical institution terminal 15 to the system server 11 after the quarantine is confirmed, and cross-checks with the information sent from the quarantined terminal 12 .

The transmitted information of the quarantined person is stored in the quarantined person DB 21 . The quarantined DB 21 includes a personal information DB 22 containing the quarantined's personal information, a biometric information DB 23 containing the quarantined's biometric information, and The quarantined location information DB (24) including real-time movement information of the quarantined person, the self-diagnosis information DB (25) including the self-diagnosis information of the quarantined person diagnosed by the quarantined at regular time intervals, and the disease information DB including information on the disease (26) may be included.

The quarantined person's biometric information is also stored in the quarantined terminal 12, and the biometric information stored in the biometric information DB 23 is stored in the quarantined terminal 12 and the biometric information transmitted from the medical institution terminal 13. contains biometric information to be transmitted.

The system server 11 transmits an authentication confirmation message for self-quarantine to the quarantined terminal 12 , and the quarantined terminal 12 sends biometric information and location information to the system server 11 for registration. First, biometric information and location information are registered in the quarantined terminal 12 and each time the app is run, biometric information must be authenticated, and the quarantined terminal 12 determines whether it matches the registered information. After (12) is authenticated, the currently authenticated biometric information and location information are sent to the system server 11 and the system server 11 checks whether the information in the personal information DB 22 and the biometric information DB 23 matches. and an identity verification success/identity verification failure message and an isolation success/isolation failure message are sent to the monitoring server 13 .

If the biometric authentication is not passed, the identity verification fails and the quarantined terminal 12 notifies the system server 11 that the biometric authentication has failed. The location information authentication is determined by the system server 11 by receiving the location information, and the location information of the quarantined person sent from the quarantined terminal 12 is stored together with the time information in the quarantined person location information DB 24

The monitoring server 13 may be a part of the system server 11 and may be installed in an institution that actually executes administrative execution. The monitoring server 13 directly transmits a warning message to the quarantined terminal 12 when self-quarantine confirmation fails or leaves the quarantined area, and when an immediate response is required, it can be executed immediately.

The information collected in the system server 11 allows the general user to check the information of the quarantined person using the user terminal 14 . One or more information such as the quarantined person's current location, movement route, quarantine period, and self-diagnosis information of the quarantined person can be checked so that people living around the quarantined place can check it at any time so that if the quarantined person leaves the quarantine location By checking the movement of the person, it is possible to prevent possible damage. In addition, when the quarantined person leaves the quarantine area, people around the quarantine area can be notified that the quarantined person has left the quarantine area.

In addition, the user terminal 14 may guide the screening medical center so that the user can self-diagnose an infectious disease and send the result to the system server 11 so that if there is a possibility of infection, the user can be tested at a nearby screening medical center. .

In the prior art, it is premised that the quarantined always carries a smartphone, and there is no need for special authentication because it does not separately check whether the person is carrying a smartphone, but in the present invention, another person leaves the mobile phone in the quarantine place In order to prevent another person from responding with a mobile phone, an authentication step using biometric information is performed. Fingerprint recognition, iris recognition, vein recognition, and facial recognition can be used for biometric information. Currently, fingerprint recognition is the most used for identity authentication in mobile phones. Since the acceptance rate of other users is 0.001% to 0.01%, it can be used commercially enough. However, there is a disadvantage that the recognition rate is lowered by sweat and dust.

Iris recognition compares the pattern, shape, color, and capillary distribution of the retina and the pattern of the iris. The false recognition rate is much lower than that of fingerprint recognition, so counterfeiting is difficult, but it is inconvenient to keep your eyes open. By comparing the vein distribution pattern of the back, it is difficult to forge because the acceptance rate of others is significantly lower than that of fingerprint recognition. However, it does not operate as a separate sensor, but uses the front camera.

Facial recognition compares three-dimensional face shapes such as eyes, nose, and mouth. Smartphone cameras or webcams can be used, but the rejection rate is 1 to 2.6% and the acceptance rate to others is 1 to 1.3%. It has a disadvantage that the recognition rate is lowered by makeup and accessories.

In the present invention, by using one or more of these biometric methods, the biometric module 31 of the quarantined terminal primarily identifies the person, and the biometric module 31 uses any one or more of the methods described above.

These biometrics are stored in the quarantined terminal 12 and can utilize the registered biometric information, and in case the fingerprint of the owner of the quarantined's smartphone is registered or changed to someone else's, the biometric information of the quarantined person is stored at regular intervals in the system. By sending it to the server 11, it is possible to check whether the quarantined person's own biometric information is correct, and it is also checked whether it matches the information sent from the medical institution terminal 15. To this end, the medical institution terminal may include a biometric information collection module, and the biometric information collected by the medical institution and the biometric information collected by the quarantine terminal 12 may be different in types. For example, the quarantined terminal 12 mainly utilizes fingerprint recognition information and intermittently collects iris recognition information, but the medical institution terminal collects only iris recognition information and can be used to check whether or not the person matches.

In addition, the biometric information requested by the quarantined person in the quarantined terminal 12 may change irregularly. For example, sometimes facial recognition information may be requested, and other times fingerprint identification information may be requested. The quarantined person is required to constantly check their biometric information, so they always carry their smartphone with them.

If the quarantined person's biometric information is matched, location information scanning is performed to check whether the quarantined person is staying in the quarantine area. In addition to GPS, a number of sensors that are built-in or may be built-in in the smartphone can be used to confirm the location of the quarantined person. Basically, GPS is used to determine the location of the quarantined terminal, but when the quarantined person is indoors, the GPS is difficult to operate, and the GPS has a large error range, and it is difficult to operate the GPS indoors. In case of being obscured by authorization, it is difficult to find out whether the quarantined person has left the quarantine place, especially if the person moves after covering the part with the built-in GPS antenna. Even if you try to check later, it will be very difficult to determine if you have ever left the containment space if the GPS is not working properly.

In the present invention, in addition to using the GPS 33, the location information collection module 32 is provided to the indoor location information of the quarantine place when the quarantined person is in the quarantine place in order to make it easier to locate the quarantined person's own terminal 12. Collect relevant information. That is, information such as sensing values of built-in sensors such as geomagnetic sensors, altitude sensors, and temperature/humidity sensors in the isolated space, Wi-Fi information and strength available in the area, Bluetooth devices and strength that can be connected, and UWB communication network and strength that can be accessed , label the quarantined place with a unique number of the quarantined person, and store the sensed values for the location in the quarantined person location information DB (24).

During the first execution, indoor location information excluding GPS information is collected and sent to the system server 11 together with GPS information and stored in the location information DB 24 .

The indoor location information does not end with a single measurement, but collects and stores the information by repeating it several times for a certain period of time. That is, even in the same house, the sensing values of the geomagnetic sensor or the altitude sensor may vary slightly, and the available Wi-Fi information and strength values may differ slightly more. In addition, values such as an acceleration sensor or a gyro sensor may be used. If the acceleration sensor and the gyro sensor are used, the movement direction and total movement distance in a specific place can be calculated without the help of other sensors.

Recently, the list of Wi-Fi that can be accessed in one place is increasing. Depending on the place, the strength of each SSID can be changed even slightly. Although one indoor location information is the standard, in order to immediately determine that the location has been changed by periodically checking and storing the indoor location information from the initially collected location information, the usual location data values must be accumulated. The indoor location information same determination module 34 of the system server 11 determines whether the collected indoor location information is within an allowable range within the same location.

However, if the distribution value sensed by the sensor suddenly changes significantly, it can be determined that the isolator is out of the corresponding position. For example, if the sensing values of the geomagnetic sensor, the altitude sensor, and the temperature/humidity sensor all deviate from the range of values that are normally observed, it can be predicted that they are leaving the isolation space. In particular, the values of the geomagnetic sensor or the altitude sensor are more sensitive to the position, and when the values of the gyro sensor and the acceleration sensor continuously change, it lets you know that the isolator is moving. The acceleration sensor detects the movement of the smartphone and is used to measure the speed of movement in three-dimensional coordinates, and when the smartphone is moving, it becomes possible to measure the speed. The gyro sensor is used to measure the direction of movement in three-dimensional coordinates. In particular, if the gyro sensor is continuously moving in the X-Y plane, not in the up-down direction, it can be detected through the gyro sensor. The quarantined person can play while throwing the smartphone up and down, left and right, but this case is not common, and even in this case, since the quarantined terminal 12 should not malfunction, the monitoring server 13 can warn the quarantined person . Going underground in a building or going to another space in a building can be identified by the value sensed by the altitude sensor.

In addition, in the WIFI-rssi method, the strength of the rssi sensed by the Wi-Fi module is inevitably changed abruptly when it leaves the isolation area because the reach distance of the Wi-Fi is very short. Even for Wi-Fi in the 2.4Ghz band, the reach does not exceed a maximum of tens of meters indoors, and as the distance increases, the signal strength decreases. In the case of the RTT method, if a certain distance is exceeded, it is possible to confirm that it is out of the quarantine area.

In addition to Wi-Fi, it is applicable to all devices that can be embedded and measured in smartphones, including Bluetooth or UWB (Ultra-Wideband Communication). Even if the Bluetooth device is not connected, it can find a connectable Bluetooth device, and the signal strength of the blue device can be measured immediately. This can be applied to all devices for short-distance communication including UWB. Even if it is covered with a permit to make operation difficult, escaping from the containment area can be easily identified.

If the quarantined person leaves the quarantined place without permission within the quarantine period, the monitoring server 13 immediately sends a warning message to request authentication again. It will be provided to the general users in the vicinity.

If identity verification fails several times or the location information does not match, if the quarantined person leaves the quarantine place through GPS or geofence, this fact is transmitted to the system server 11 and the real-time location and movement path of the quarantined person are tracked. And, if necessary, the monitoring server 13 can take administrative measures immediately.

In addition, a danger alert is notified to the user terminal 14 of the non-infected user, and the movement of the quarantined person is disclosed while avoiding contact with the quarantined person. The information of quarantined persons can be viewed by country and region, information such as quarantined persons and their movement routes, quarantine period, and entry ban information by country.

The user terminal 14 can access the system server 11 to check information about the infectious disease, and can also check information about the quarantined person.
