Description

Visitor check-in and check-out method and visitor check-in check-out system using the same {Check in and Check out Method of Visitor and System thereof}

The present invention relates to a check-in and check-out system for visitors to multi-use facilities such as public institutions or hospitals. Currently, in order to track and manage infectious diseases such as Corona in the use of multi-use facilities, information on visitors is collected and when a confirmed infectious disease visits, visitors at the same time are tracked and infectious disease confirmed information is provided, thereby tracing contacts with the confirmed infectious disease. We are managing it to prevent the spread of infectious diseases.

The prior art related to the present invention is disclosed in Republic of Korea Patent Publication No. 10-2021-0148555 (published on December 8, 2021). Figure 1 is a flowchart of a method for managing access to a multi-use facility using the conventional hybrid location information and dynamic QR. In Figure 1, the conventional method of managing access to a multi-use facility using hybrid location information and dynamic QR requires that visitors to a multi-use facility (hereinafter referred to as 'store') install the app running according to this embodiment in advance, but installation is not possible. If it is not installed, installation is required upon entry. At each store, a QR code, barcode, or identification code that can be recognized by the user's mobile phone is scanned before entering the store. If the app is not installed, the app is downloaded and installed from the management server (11) or a download site for each OS. When the app is downloaded, personal information such as name and phone number is entered, and the entered number and subscription information of the mobile phone holder are authenticated through the telecommunication company or management server (11) to confirm that the information entered is the holder of the mobile phone. . At this time, biometrics such as fingerprint, iris recognition, voice, facial recognition, and vein recognition are used to authenticate that the person holding the mobile phone is not holding someone else's mobile phone, but is authenticating with his/her own mobile phone and his/her own information. For biometric identification, the user terminal 13 may include a biometric authentication module 38. However, the biometric authentication module 38 may be optional, and since users rarely leave their mobile phones behind these days, an OK message can be issued simply by recognizing the identification code with the user terminal 13. When biometric authentication is completed, the user terminal 13 displays an OK message indicating that the user can enter the store, and the user can enter the store by showing the OK message displayed on the user terminal to the security guard. In addition, when biometric authentication is completed, the user terminal 13 where the user is located collects location information, encrypts the collected location information, and transmits it to the management server 11. The location information used in this embodiment can utilize WIFI (rssi/rtt, BLE, geomagnetism, base station information, barometric pressure, UWB) to check location information indoors in addition to location information using GPS. . In the case of WIFI, Mac Address, SSID, RSSI, RTT, etc. can be used, and signals searched at the location can be used for location authentication. Bluetooth information also uses Bluetooth identification information. Compared to existing location information confirmation using only GPS, in this embodiment, location information indoors is confirmed using information such as WIFI-rssi/rtt, BLE, geomagnetism, barometric pressure, and UWB mentioned above in addition to GPS information. It is called location information. In this embodiment, after biometric authentication, hybrid location information including GPS information is collected to confirm whether the user has entered the store and whether the user continues to stay inside the store. In this embodiment, in addition to biometric authentication upon entry, it is possible to check whether the store the user is trying to enter is the store with the recognized identification sign through location confirmation and then display an OK message. Identification signs such as QR codes and barcodes are different for each store and can be changed at regular intervals. After recognizing the identification sign with the user terminal 13, the management server 11 sends a separate QR code for confirmation in addition to the OK message to the user. It can be sent to the terminal (13). In places where security must be strengthened at the time of entry, the entry message in the form of a QR code sent to the user terminal 13 can be verified once again by checking the entry message at the time of entry. In addition, the QR code sent to the user terminal 13 plays the same role as a pass, so when a security guard, etc., tries to check whether a visitor in the store has followed the regulations and entered, the QR code sent to the user terminal 13 is displayed. It will be given. When using only GPS information, if there are multiple stores in one building (restaurants, entertainment bars, clubs, bars), it will not be possible to determine which store you are entering, but when using hybrid location information including WIFI signals, the Wi-Fi used for each store Since the signal value and altitude sensor value are different, you can check which store you entered. Simply by determining the MAC address and SSID value of the strongest Wi-Fi signal, you can easily check which store you 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, and the user's visit information is encrypted and transmitted to the management server (11). When you leave, the time you leave is also saved. Information stored in the store-specific visitor DB (21) cannot be accessed arbitrarily by users and can be accessed only when necessary to determine the visitor's movement path. 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, if the indoor location verification module 32 of the user terminal fails to confirm that the user is indoors, it is recognized as leaving the store. If the user terminal 13 cannot 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 exit time along with the user's identification information to the management server 11, and the management server 11 encrypts the information in the visitor database 21 for each store. and save it. Additionally, when checking out of a store, the management server 11 updates the visitor DB 23 with the information of the user who left the store along with the check-out time. Because the user's identification information includes personal information, no separate information is stored in the store server 12. In the case of a store with a security guard, the security guard can check in real time when users are leaving. Similarly, upon entry, users can be checked one by one using a QR code, and a check-in message is sent to the user's terminal using the QR code to be sent to the management server. You can only gain access by recognizing the check-in message received from . If there is a security guard, when leaving, you can recognize the identification sign similarly to when entering, then show the OK message received from the management server to the security guard and leave. However, if the check-in or check-out message does not appear even when there is no security guard, the management server 11 notifies the store server 12 that there is an error and has the store owner check it directly. If necessary, the details can be transmitted to the supervisory agency server 14, such as a government office, so that terminals with errors can be utilized in the event of an infectious disease outbreak in the future. The authentication module 37 of the management server 11 authenticates the user of the user terminal 13 using the user information, and the access confirmation module 36 compares the identification mark to determine whether the user is checking in and checks the user terminal 13. The message transmission module 35 serves to transmit the check-in message or check-out message from the management server 11 to the user terminal 13. Additionally, if you use a mobile phone other than your own or try to enter the store without verifying your identity when leaving another store, an error message may appear, and this information is stored in the error occurrence DB 26. The store server 12 does not separately store information about users entering and leaving the store, and can only check information necessary to manage the people entering and leaving the store by accessing the management server 11. However, the user terminal 13 can separately store information about the stores visited by the user and access times, so that each user can easily check which places they visited when an infectious disease is confirmed. Through this method, when a confirmed infectious disease occurs, people who were in the same place/time can be quickly identified, making it effective in initial response in the event of a new infectious disease outbreak. In addition, in the case of not only multi-use facilities but also small stores (restaurants, flower shops, convenience stores), etc., it can be managed by simply placing an identification code in the store and securing a means (Wi-Fi, Bluetooth, etc.) to confirm indoor location without investing a large amount of money. Since the server 11 determines the information of visitors and manages entry and exit times separately, there is no need to build a separate system on its own. In addition, the encrypted information is stored only on the management server 11, and when necessary, only authorized personnel can access the DB to obtain visit information of confirmed patients, thereby reducing the possibility of personal information being leaked.

The visitor management method using the QR code as described above requires recognition by operating a smartphone in front of the QR code reader in order to check in, so the waiting time is long during crowded lunch hours or commuting hours, and it is difficult to maintain the distance between waiting people. Because it is not easy, close contact may occur. In addition, the method of using QR codes requires loading the QR code with a smartphone, making it difficult for the elderly or young children to use.

In order to solve the problems of the prior art as described above, the visitor check-in and check-out method using UWB includes activating the BLE communication module and the UWB communication module of the visitor's smartphone equipped with the BLE communication module and the check-in/check-out module.
