Description

Multi-use facility access management and location verification solution using hybrid location information and dynamic QR {ACCESS MANAGENT SOLUTION}

The present invention relates to a multi-use facility access management and location verification solution using hybrid location information and dynamic QR.

The present invention relates to a multi-use facility access management and location solution using hybrid location information and dynamic QR, and relates to biometric recognition (fingerprint, iris, face, voice, vein) and location information (GPS, WiFi - rssi, rtt) of an infected person's smartphone. (Mac adddress, SSID), BLE, geomagnetism, barometric pressure, UWB) technology, it is about self-quarantine and information management solution for infected person using information and pattern of base station information of telecommunication company.

Due to the virus pandemics such as SARS, MERS, H1N1, and Corona, the damage to countries around the world is getting serious. Many countries are experiencing the rapid spread of the virus without even knowing the route. In addition, another damage is expected due to the emergence of unpredictable mutated viruses every year, but no definitive solutions or preventive measures are provided.

In the case of COVID-19 infection, the transmission of infection occurs very quickly, so an epidemiological investigation is very important to prevent further spread. It is considered important, and these contents were also enacted in the Act on the Prevention and Management of Infectious Diseases.

In particular, in a situation in which a quarantine management system is needed for places used by an unspecified number of people with high risk of infection, the government recommends establishing an infection control system for facilities used by a large number of people by preparing guidelines for responding to collective facilities and multiple-use facilities. was designated to give management responsibility and made it compulsory to report symptomatic persons.

However, due to the rapid increase in the number of infections, it was revealed that there are problems with this quarantine management system. In particular, due to the high risk of infection, the number of infected people occurs in closed multi-use facilities with high population density, and the 7th infection is occurring, which is likely to spread to the nth infection. .

In addition, at a hospital in Seoul, four nurses with unknown routes of infection tested positive, but the route of infection was not confirmed, so CCTV was secured to investigate the movement of the infected. Due to the poor access control system, response to infectious diseases is delayed and there are difficulties in quarantine.

In the past, visitors were forced to write their contact information, name, and address by hand, but it is difficult to manage, and many people use writing instruments and access books in common, which exposes them to more risk of infection. Or, it may be exposed to the business owner, and there is a possibility of entering false information.

Although the borders of each country are gradually opened and there are signs of returning to normal, there is no sign of an end to the infectious disease and any form of infectious disease can remain, so it is urgent to develop a solution for preventing and preventing infectious diseases.

In relation to these infectious diseases, Republic of Korea Patent Registration No. 10-1779705 'Internet of Things-based New Infectious Disease Prediction Response Platform System' injects an antibody of an infectious pathogen virus and measures the light intensity, wavelength, and color of the light source according to the infectious pathogen virus. Including an infectious disease predictor that detects pathogenic viruses, the smart terminal enables users to self-diagnose the virus, but these infectious diseases relate to viruses that have been completely analyzed and cannot be used for sudden viruses.

The present invention has been devised to solve the above problems, and an object of the present invention is to provide a system for managing the occupants of a multi-use facility at the time of an infectious disease outbreak.

In order to achieve the above object, an access management system for preventing the spread of infectious diseases using hybrid location information is provided. The management server 11 is connected to the store server 12 and a plurality of user terminals 13 through a network and managed The server 11 includes a store DB 22 and a reference DB 25 including store information. The store DB 22 stores visitor information and access time for visiting the store, and the reference DB 25 stores the store information. In order to store pre-measured data for each indoor location, when the user terminal 13 is designated in advance and recognizes the identification code (QR, barcode) provided in the store, the user terminal 13 transmits the recognized identification code and user information. It is transmitted to the management server 11, and the access confirmation module 36 recognizes the user and the store, lists it in the visitor DB 23 in the store DB 22, and sends a check-in message to the user terminal, and the location confirmation module 31 transmits data for indoor location confirmation stored in the reference DB (25) to the user terminal, compares the data for indoor location confirmation sent from the user terminal with the information in the reference DB (25) to verify whether the store is correct, and If the indoor location confirmation module 32 of 13) does not confirm that the user is indoors, it is regarded as checked out and the management server 11 updates the check-out time in the visitor DB 23 to provide information on the user entering and leaving the store. make it manageable

When the user terminal 13 recognizes the identification mark of the store for admission, and the identification mark matches the store, the management server 11 displays another identification mark for admission and confirmation to the user terminal 13 to the user terminal 13 ) so that it can be used in the store.

The indoor location information stored in the reference DB 25 may be a part of values measured by users who visit first.

Since the user terminal 13 includes an indoor location verification module 32, it is possible to verify that the user is staying indoors by verifying the indoor location data detected in the store.

The in-store real-time visitor confirmation module 34 causes the user terminal 13 to recognize a separate identification code and verifies whether the user on the in-store user DB 24 is correct from the information transmitted from the user terminal 13 .

The data used for indoor positioning is any one or more of WiFi-rssi/rtt (including MAC address, SSID), BLE, geomagnetism, barometric pressure, UWB, and unique identification values and strength values of base stations.

The identification mark used in the store and the identification mark transmitted to the user terminal may be changed at regular intervals.

The biometric information includes any one or more of a fingerprint, an iris, a face, a voice, and a vein.

The management server 11 may further include an emergency guide module 27 for transmitting emergency guide information to the in-store user terminal 13 when an emergency occurs.

According to the configuration described above, it is possible to easily create a list of people who were actually in the store at the same time as the visit time of the visitors to the multi-use facility, which has the effect of providing useful information for epidemiological investigation when an infection occurs.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 1 shows an embodiment according to the present invention. In the present invention, a visitor to a multi-use facility (hereinafter referred to as a 'store') must install the app driven in accordance with the present invention in advance, but if it is not installed, installation is required upon entry. In each store, a QR code or barcode or an identification code recognizable by the user's mobile phone is scanned before entering the store, but if the app is not installed, the app is downloaded and installed from the management server 11 or the OS-specific download site.

When the app is downloaded, personal information such as name and phone number is entered, and the entered number and the registration information of the mobile phone holder are authenticated by confirming that the information entered through the communication company or the management server 11 is the holder of the mobile phone. . At this time, biometrics such as fingerprint, iris recognition, voice, face recognition, and vein recognition are used to authenticate that the person holding the cell phone does not own another's cell phone, but that it is authenticated with their cell phone and their own information. For biometric recognition, the user terminal 13 may include a biometric authentication module 38 . However, the biometric authentication module 38 may be optional, and since the user rarely leaves his or her cell phone in recent years, an OK message may be issued only by recognizing the identification code with the user terminal 13 .

When the biometric authentication is completed, the user terminal 13 that can enter the store displays an OK message, and the user can enter the store by showing the OK message displayed on the user terminal to the security personnel.

In addition, when biometric authentication is completed, the user terminal 13 at the location of the user collects location information, encrypts the collected location information, and transmits it to the management server 11 .

The location information used in the present invention may utilize WIFI-rssi/rtt, BLE, geomagnetism, base station information, barometric pressure, UWB) to check indoor location information in addition to location information for determining a location using GPS. In the case of WIFI, Mac Address, SSID, RSSI, RTT, etc. can be used, and signals found in the location can be used for location authentication. Bluetooth information also uses Bluetooth identification information and the like.

In the present invention, it is a hybrid location to check location information indoors using information such as WIFI-rssi/rtt, BLE, geomagnetism, barometric pressure, UWB, etc. called information.

GPS is to check the user's location by receiving signals from several satellites orbiting the Earth. In addition, since the GPS can be turned on and off as many times as possible in the settings of the mobile phone, if the user tries to check the location information using only the GPS information, if the user turns off the GPS and moves, there is no means to confirm the user's location.

In dense areas, between high-rise buildings, or in densely populated areas or downtown areas, accurate location movement cannot be confirmed due to GPS distance errors.

For example, if a user who entered store 1 moves while turning off the GPS, even if he enters another store 2, the movement line is not checked. In the present invention, when a user enters a room, it is checked whether the store identified by an identification code such as a QR code is correct, and whether the user continues to stay in the store is checked. For this purpose, hybrid location information is used instead of GPS information for location confirmation.

In the present invention, after biometric authentication, hybrid location information including GPS information is collected to check whether the user has entered the store, and it is confirmed whether the user continues to stay in the store. In the present invention, an OK message may be displayed after confirming whether the store the user is trying to enter is the store of the recognized identification mark through location confirmation other than the birth authentication upon entry. Identification signs such as QR codes and barcodes are different for each store and can be changed at regular intervals. It can be sent to the terminal 13 . In a place where security needs to be strengthened at the time of entry and exit, the entry message in the form of a QR code transmitted to the user terminal 13 may be checked again at the time of entry so that it can be verified once more.

In addition, the QR code sent to the user terminal 13 acts like a pass, so when security personnel try to check whether a visitor in the store has followed the rules, the QR code sent to the user terminal 13 is shown. will give

If only GPS information is used, if there are multiple stores in one building (restaurants, entertainment pubs, clubs, pubs), it is impossible to check which store to enter, but if hybrid location information including WIFI signal is used, the Wi-Fi used for each store Since the value of the signal or the value of the altitude sensor is different, it is possible to check which store has entered. Simply by looking at the MAC address and SSID value of the Wi-Fi signal that has the strongest strength, you can easily check which store you have entered.

When the user enters the store, the user's visit information is encrypted and transmitted to the management server 11, and the management server 11 records the visit time, name, mobile phone number, etc. in the visitor DB 21 for each store. When you leave, the time you leave is also saved.

The information stored in the visitor DB 21 for each store cannot be accessed arbitrarily by the user, and can be accessed only when necessary to understand the movement of the visitor.

The management server 11 notifies the store server 12 through the network whenever a user enters the store, and the management server 12 creates a list of users in the store and stores it in the in-store user DB 22. When the user leaves the store, when the indoor location verification module 32 of the user terminal fails to confirm that the user is indoors, it is recognized that the user leaves the store. If the user terminal 13 does not verify that the indoor location verification module 32 is indoors, it notifies the management server 11 of this fact.

Confirming that the user terminal 13 leaves the room, the user terminal 13 transmits the user's identification information along with the exit time to the management server 11, and the management server 11 encrypts the visitor DB 21 for each store. to save it. In addition, when checking out of the store, the management server 11 updates the information of the user who has left the store to the visitor DB 23 together with the check-out time.

Since the user's identification information includes personal information, separate information is not stored in the store server 12 .

In the case of a store with security guards, security guards can check real users leaving in real time. Similarly, when entering, they can check users one by one using a QR code. Upon entry and exit, the check-in message must be recognized by a separate recognizer to enable entry and exit. If there is a security guard, when you leave, you can recognize the identification mark similarly to when you enter, show the OK message received from the management server to the security guard, and then leave.

However, if the check-in or check-out message does not appear even if there is no security guard, the management server 11 informs the store server 12 that there is an error and allows the store owner to check it directly. If necessary, the relevant details may be transmitted to the supervisory authority server 14 such as government offices, and the terminal in which an error has occurred may be utilized in the event of an infectious disease or the like in the future. The authentication module 37 of the management server 11 authenticates the user of the user terminal 13 using the user's information, and the access confirmation module 36 compares the identification marks to determine whether the user checks in, and the user terminal The message sending module 35 serves to transmit a check-in message or a check-out message of the management server 11 to the user terminal 13 . In addition, if you use a mobile phone other than your own mobile phone or try to enter a store without verifying your identity when leaving another store, an error message may appear, and these contents are stored in the error occurrence DB 26 .

The store server 12 does not separately store information of users entering and exiting the store, but can access the management server 11 to check only the information necessary to manage people entering and leaving the store. However, the user terminal 13 may separately store information on stores visited by the user, access time, etc., so that each user can easily check which place he or she visited when an infection is confirmed.

This method is effective in early response to the onset of a new infectious disease because it is possible to quickly identify people who were in the same place/time when a confirmed case of an infectious disease occurs. In addition, in the case of multi-use facilities as well as small stores (restaurants, flower shops, convenience stores), it is managed if only the identification code is provided in the store without a large investment and a means for indoor location confirmation (Wi-Fi, Bluetooth, etc.) is secured Since the server 11 grasps the information of entry/exit and manages the entry/exit time separately, there is no need to construct a separate system by itself.

In addition, the encrypted information is stored only in the management server 11, and if necessary, only a person with authority can access the DB to obtain the visit information of the confirmed patient, thereby reducing the possibility of personal information leakage.

Fig. 2 shows a block diagram showing the configuration of a system according to the present invention. The management server 11 according to the present invention has a user DB 21 including information of users who have subscribed by installing an app on the user terminal 13, and also stores including a list of stores using the system according to the present invention. DB 22 is included. The store DB 22 has a visitor DB 23 including details of visitors who have visited the store by store/date, and the visitor DB 23 has a name, phone number, address, gender, and age that can identify the visitor. To identify the visitor by including one or more of the following: In addition, the visitor DB 23 records the time the user enters the store and the time the user leaves the store.

The visitor DB 23 includes a list of users currently in the store, and when they visit the store, they are stored in the real-time visitor DB 24 and are moved to the visitor DB 23 as they leave the store.

The real-time visitor DB 24 may be used when the security guard checks whether the user in the store has entered the store effectively, and can be used when the security guard checks the user. When it is necessary to check whether or not a valid entry is made in a multi-use facility, the user terminal 13 transmits the user's information to the management server 11 when the security officer allows the user to recognize the previously agreed identification code using a mobile phone. It is sent to confirm whether the user is in the real-time visitor DB 24 , and if confirmed, an OK message or an admission message serving as a pass is transmitted to the user terminal 13 . The identification code used at this time may be a two-dimensional bar code such as a QR code, and the management server 11 in the management server 11 is the in-store real-time visitor confirmation module 34 when a QR code for real-time visitor confirmation in the store is transmitted. After confirming that the user information stored in the user terminal 13 and sent to the management server 11 is in the real-time visitor DB 24, the message sending module 35 sends an OK message or an error message. make it In the case of an industry where there are not many users at the same time, such as a convenience store, an employee of the store can check whether the user is being managed by an OK message sent to the store server 12 when the user enters, and if necessary, the You can check the user with the same simple information.

When the user enters the store, the location confirmation module 31 activates the app of the user terminal 13 when the user recognizes the identification code as the user terminal 13 for admission confirmation, and in the case of a QR code, the user terminal 13 The user information and the recognized identification code are sent to the management server 11, and the entry/exit confirmation module 36 determines the validity of the recognized identification code, and uses the received user information to store user information in the in-store user DB 24. list up and move the user information from the in-store user DB 25 to the visitor DB 23 when check-out is confirmed.

The location confirmation module 31 compares the hybrid location information value currently measured with the value previously stored in the reference DB 25 in which the hybrid location information value unique to each store is stored, and an identification code (QR code) to which the store the current user entered is assigned. ) to check whether the Data of the reference DB 25 may be downloaded to the user terminal 13 and used.

Even with the WIFI signal, each store uses a different MAC address and SSID, and it is possible to check whether the store is inside the store as a Wi-Fi strength signal or the value sensed by the barometric pressure sensor and Bluetooth sensor. put The reference value can use hybrid location information sent by users who visit the store. The hybrid location value sent by people who initially visited is used as information to check the indoor location of those who visit later. . People who visit for the first time judge whether they are indoors by using the value measured by their terminal as a reference.

The reference DB 25 stores not only the SSID of the store but also information such as WIFI-RTT around the store. The MAC address, SSID, and RSS values are scanned and stored. The RSSI value is a unique value or a processed value for judgment. can be used

Among the Wi-Fi information stored in the reference DB, scan values of MAC address and SSID are stored in various locations in the store and compared with values scanned by the user terminal 13 . In particular, since the MAC address is unique to each device, even if it is a similar SSID value, the same value cannot come out.

It is judged by comparing the unique value and the patterned value of the RSSI signal strength among the matched WIFIs with the stored value within an appropriate range. This will be described later.

In addition, the sea level pressure and temperature of the area closest to the store are obtained from open data, the atmospheric pressure is scanned using the sensor, the altitude is calculated, and the altitude is stored in the reference DB. It is compared with the stored value to determine whether it is located indoors.

In addition, the WFI-RTT value can be used. In the isolated location, information of nearby Wifi-RTT APs (Mac Address, SSID, RSSI (unique or processed value), distance value between the current and AP (eigen value or processed value)) It scans in advance and stores it in the reference DB. Among the Wifi information scanned from the user terminal, it is judged whether the scanned value of MAC address and SSID match the stored value and check the count. Among the matched scan Wifi, the unique value of RSSI signal strength and RTT distance and patterned values are compared with the stored values within an appropriate range to determine whether they are indoors.

In addition, the information (CID, PCI, RSSI, RSRP, RSRQ) of neighboring base stations is scanned in the isolated location and stored in advance, and the matching count of CID and PCI values among the base station information scanned at the location where the user terminal is located is calculated and then RSRP signal strength (Eigenvalues, processed values) are compared within an appropriate range to determine whether they are indoors.

In addition, Bluetooth scans the surrounding BLE/Bluetooth information (address, name, strength) from the isolated location and stores it in the reference DB, and compares the matching count and signal strength information of the stored values with the information scanned from the user terminal to determine whether it is indoors or not. judge

The following shows an example of indoor location determination.

1) An example of information stored in the reference DB for indoor location determination is shown.

Several Bluetooth or WIFI information used in the above comparison can be used, but in the case of altitude, an error range of about 4m is acceptable.

In the case of Wifi, it is judged whether the matching WIFI Mac Address matches or not, and if the number of matches is more than one, an error range of about 10dBm is allowed to compare RSSI.

The base station determines whether CID and PCI match and compares RSRP, and an error range within 8 dBm may be allowed.

Bluetooth determines whether Address and Name match and compares RSSI, and an error range of 10 dBm can be tolerated.

It is not necessary to use all of the information mentioned above, but only enough information to confirm that it is in the store.

The user terminal 13 includes an indoor location verification module 32, and after downloading the reference value of the store from the reference DB 25, checks whether the user stays indoors until the user leaves the store. If the location is not identified in , it is reported as checkout and the management server 11 is notified of this fact. The indoor location verification module 32 also checks whether the GPS value detected outdoors by using the GPS changes.

3 shows another embodiment. In FIG. 3 , the personal identification module 38 for biometric authentication enters the user terminal 13 , and the reference downloaded from the reference DB 25 is stored. In addition, user information, store information, visitor information, reference information, and error history information are stored in DB.

Through the integrated management system, access to multiple stores such as franchises can be managed, and the number of visitors to each store, visit date, stay time, number of visits, and visitors at the same time can be checked, and the collected customer DB can be used for customer management and marketing in the future. .

In addition, in case of an emergency, it becomes possible to send an emergency message to all customers in the store from the manager app. By sending a push notification to the user terminal 13, it is possible to update and check the total number of users and user details located in the hazardous area through the manager system at regular intervals. to support the call or notification function to the designated manager, and if the user consents, the user's location information can be sent to the manager system to know the current location.

Also, according to the present invention, it is possible to check the current number or location of visitors in the building, as well as the location in the room, as well as simply being located indoors. It is possible to check the location indoors because the MAC address, SSID, strength, etc. such as WIFI or Bluetooth confirmed in the building are aggregated. Using this, it is possible to provide space curation and indoor location guide service, to check the density and stay time for each area in a building, to navigate indoors, and to check the number and location of people who have not escaped in an emergency.
