As shown in FIG. 1, the NFC-based access control system to which the present invention is applied includes a terminal 10, an entrance terminal 20, a server 30, a DB (DataBase) 40, and a generation terminal 50. ).

Looking at the respective components, first, the terminal 10 is a portable terminal having a NFC (Near Field Communication) function, and includes a mobile communication terminal, a wireless LAN terminal, a smart phone and the like.

In addition, when the terminal 10 receives an access request from the user after the access application is executed by the user, the terminal 10 transmits previously stored authentication information to the door terminal 20 based on NFC communication. That is, the user requests access using a soft key (generation member access button, normal visitor access button, special visitor access button) provided according to the user's qualification (generation member, normal visitor, special visitor) after executing the access application. do.

At this time, the terminal 10 stores authentication information corresponding to the qualification of the user. That is, in the case of the terminal 10 of the household member, the authentication key and the password are stored, and in the case of the terminal 10 of the visitor, the information of the visitor (name, phone number, photo, etc.) and the telephone number list are normally stored. The terminal 10 of the special visitor stores the special visitor's information (name, affiliation, personal number, phone number, photo, authentication key, etc.).

In addition, the terminal 10 displays the information of the household member received from the door terminal 20 on the screen.

In addition, the terminal 10 receives a household number to be visited from a special visitor.

The entrance terminal 20 is a terminal installed at the lobby entrance of the apartment to lock / unlock the door. The terminal 20 has an NFC function and transmits authentication information obtained from the user terminal 10 to the server 30 only. Only based on the authentication result received from the server 30 maintains or releases the locked state of the door.

In addition, the door terminal 20 only transmits the information of the household member received from the server 30 to the terminal 10.

In addition, the front door terminal 20 calls the corresponding generation terminal 50, transfers information of the normal visitor or special visitor to the corresponding generation terminal 50, and is equipped with a camera to display the face image of the normal visitor or special visitor. The photographing is transmitted to the generation terminal 50.

In addition, the door terminal 20 maintains / releases the locked state of the door according to the locked state maintaining / release signal from the household terminal 50.

The DB 40 stores household information (only, dong, lake, etc.), personal information (name, phone number, photo, etc.), authentication key and password as the information of the household member, and personal information (name) for the special visitor. , Affiliation, personal number, phone number, photo, etc.) and authentication key, and stores the search history and information of special visitors, visit information (date, generation, purpose, etc.).

The server 30 only authenticates the authentication information received from the door terminal 20 based on the DB 40, and then transfers the authentication result to the door terminal 20.

That is, only the server 30 performs authentication based on the authentication key and password in the case of the access request of the household member, and in the case of the access request of the household member, it is determined whether the household member exists on the telephone number list and the special visitor. In the case of an entry request, the special visitor is authenticated by interworking with an external authentication server if the pre-reservation reservation is not made. To pass.

The generation terminal 50 receives a call from the entrance terminal 20, receives the visitor's information and the real-time photographed image from the entrance terminal 20, and provides the call to the household member.

In addition, the household terminal 50 transmits the locked state keeping / release signal of the door to the door terminal 30 in response to a request from the household member.

In addition, the household terminal 50 is requested to enter and exit from the server 30 at the time of advance reservation of the special visitor, and transfers the decision of the household member (access approval / access blocking) to the server 30 only.

Hereinafter, an access control method when a household member requests access will be described with reference to FIG. 2.

In the case of a household member, if the authentication process is normally performed when the apartment is accessed, the door should be opened immediately without calling the household terminal 50. That is, if the terminal 10 of the household member is close to the entrance terminal 20, the authentication process is made, and if the normal authentication, the door should open immediately.

To this end, first, the household member executes the access application in his terminal 10 (201), touches the household member access button in the form of a soft key (button key method), and then closes the door terminal 20 (202). ), Previously registered authentication information is transmitted to the door terminal 20 based on NFC (203). At this time, the authentication information includes an authentication key and a password.

Thereafter, the entrance terminal 20 only transfers the authentication information received from the terminal 10 of the household member to the server 30 (204).

Thereafter, only the server 30 authenticates the authentication information received from the door terminal 20 based on the information of the household member stored in the DB 40 and transmits the authentication result to the door terminal 20 ( 205, 206). At this time, the information of the household member includes household information (only, town, lake), user information (name, phone number, photo, etc.), authentication key, and password.

Thereafter, the entrance terminal 20 releases the locked state of the door if the authentication result is normal, and maintains the locked state of the door (207 to 209).

On the other hand, in the process of registering the authentication information in the terminal member 10 of the household member, first, the household member executes the access application on his terminal 10 and then touches the registration information registration button in the form of a soft key, The fields for entering, dong, lake, and user information (name, phone number, photo, etc.) are displayed.

Input the information here, touch the confirmation key and approach the door terminal 20, the input information is transmitted to the door terminal 20, the door terminal 20 only receives the received information server 30 To pass).

That is, the terminal 10 of the household member receives the various information from the household member after the access application is executed by the household member and then transmits the input information to the door terminal 20 based on NFC. In this case, the storage path is set for the photo.

Thereafter, the entrance terminal 20 merely transfers the received input information to the server 30.

Thereafter, when only the server 30 requests approval from the household terminal 50 of the household member, the household terminal 50 merely transmits the preset password to the server 30. In this case, the password is set in advance by a member of the household. Of course, other household members can enter a password in real time.

After that, only the server 30 generates the authentication key for the terminal 10 of the household member and stores it in the DB 40 together with the password received from the household terminal 50.

Then, only the server 30 transmits the authentication key and password to the door terminal 20, the door terminal 20 transmits the authentication key and password to the terminal 10 of the household member based on NFC. Then, the terminal 10 of the household member registers the authentication key and password as authentication information of the household member.

This authentication information registration process is performed once.

In addition, the household member may visit the management office and be assigned an authentication key only through an NFC terminal directly connected to the server 30. At this time, the household member enters the password into the NFC terminal, and receives the password from the NFC terminal to the terminal 10 of the household member. As a result, the household member 10 stores the authentication key and the password.

Hereinafter, an access control method in the case where a normal visitor (acquaintance) requests access will be described with reference to FIG. 3.

In the case of a normal visitor, when the apartment is normally authenticated when the apartment is accessed, the door is opened under the control of the household member after the process of calling the household terminal 50 and transmitting the normal visitor information to the household terminal 50. That is, if the visitor terminal 10 is close to the entrance terminal 20, authentication is normally performed, and if the visitor terminal 10 is normally authenticated, the generation terminal 50 is called immediately.

First, when a normal visitor executes an access application in his terminal 10 (301), touches a normal visitor access button in the form of a soft key, and then approaches the front door terminal (302). The stored authentication information is transmitted to the door terminal 20 based on NFC (303). In this case, the authentication information usually includes visitor information (name, phone number, photo, etc.), and a list of phone numbers stored in the terminal 10.

Thereafter, the door terminal 20 normally transmits the authentication information received from the visitor's terminal 10 to the server 30 (304).

Thereafter, the server 30 compares the telephone number list with the DB 40 which stores household member information (name, telephone number, etc.) and checks whether the household member exists on the telephone number list (305). At this time, it is preferable that the server 30 shortens the processing time when comparing the telephone number list and the DB 40 with the information of the household member matched with the corresponding door terminal 20.

As a result of the check 305, if there is a household member on the telephone number list, the inquiry history is stored in the DB 40 (306), and the information of the household member is transmitted to the door terminal 20 (307). In this case, all the information may be transmitted as the information of the household member, but only the name and telephone number of the household member may be transmitted for the protection of personal information, and other information may not be transmitted.

Thereafter, the entrance terminal 20 merely transfers the household member's information (name and phone number) received from the server 30 to the terminal 10 of the visitor (308). In general, the visitor terminal 10 displays the received household information on the screen (309).

In addition, the entrance terminal 20 calls the corresponding generation terminal 50 (310), and the real-time photographed image of the normal visitor with the information (name, phone number, photo, etc.) of the normal visitor to the generation terminal 50; Transmit (311).

Then, as illustrated in FIG. 6, the generation terminal 50 displays the real-time photographed image of the normal visitor together with the visitor's information (name, phone number, photo, etc.) on the screen. At this time, a call path is established between the entrance terminal 20 and the corresponding generation terminal 50.

Thereafter, the generation terminal 50 transmits the maintenance / release signal of the locked state to the door terminal 20 according to the request of the household member (312).

In this case, the door terminal 20 is only the information of the household members received from the server 30, that is, when there are a large number of household members on the telephone number list, usually, the visitor's terminal 10, the name and telephone number of the household member It is usually sent one by one from the visitor.

As a result of the check 305, if there is no household member on the telephone number list, a simple notification message is displayed and the process ends. Here, the simple reminder phrase may be, for example, "105 friends do not live." It can also be output by voice.

In the above example, if there is a household member stored in the visitor's phone number list, the household member's information is disclosed to the general visitor. However, as another example, the information is applied only to the general visitor (friend list) registered by each household member to protect personal information. It can also be made public.

That is, when a household member exists on the telephone number list of a normal visitor, the household member's information may be disclosed only when the normal visitor exists in a friend list created by the household member. In this case, the friend list includes a friend list established through various social networks.

Hereinafter, referring to FIG. 4, as an access control method when a special visitor (a postman, a courier, etc.) requests access, a case in which an advance reservation is not made will be described.

First, the terminal 10 of the special visitor undergoes an authentication process from an authentication server belonging to the institution or company to which the special visitor belongs, and the special visitor's information (name, affiliation, personal number, telephone number, photo, etc.) and authentication key as authentication information. Is stored (401).

Thereafter, the special visitor executes the access application in his terminal 10 (402), inputs the household number to be visited (403), touches the special visitor access button in the form of a soft key, and then enters the entrance terminal 20. In step 404, the authentication information stored in the terminal 10 of the special visitor and the input generation number are transmitted to the door terminal 20 based on NFC (405).

Thereafter, the entrance terminal 20 only transfers the authentication information received from the terminal 10 of the special visitor to the server 30 (406).

After that, only the server 30 requests authentication by transmitting authentication information of the special visitor to the authentication server of the institution or company to which the special visitor belongs (407).

After that, only the server 30 transmits the authentication result received from the authentication server to the door terminal 20 (408, 409).

Thereafter, when the entrance terminal 20 normally authenticates (410), the household visitor 50 of the household that the special visitor wants to visit (411), the information (name) of the special visitor to the household terminal 50 (name) , Affiliation, personal number, phone number, photo, etc.) and the real-time shot image of the special visitor is transmitted (412).

Then, as illustrated in FIG. 6, the generation terminal 50 displays the real-time photographed image of the normal visitor together with the visitor's information (name, phone number, photo, etc.) on the screen. At this time, a call path is established between the entrance terminal 20 and the corresponding generation terminal 50.

Subsequently, the household terminal 50 transmits the lock / maintenance signal of the locked state to the door terminal 20 according to the request of the household member (413).

Hereinafter, referring to FIG. 5, a case in which a special visitor (a postman, a courier, etc.) requests access is described as a case where an advance reservation is made.

First, the terminal 10 of the special visitor undergoes an authentication process from an authentication server belonging to the institution or company to which the special visitor belongs, and the special visitor's information (name, affiliation, personal number, telephone number, photo, etc.) and authentication key as authentication information. Is stored (501).

After that, when the special visitor only accesses the server 30 and registers the special visitor's information and the visit information (date, lake, purpose, etc.), the server 30 merely receives the input of the special visitor's information and visit. Information (time, date, lake, purpose, etc.) is stored in the DB 40 (502).

After that, only the server 30 calls the generation terminal 50 of the household to determine whether to enter or leave (503, 504). At this time, by calling the terminal (not shown) located in the guard room, the guard can decide the approval directly. If the guard decides to approve, it is desirable that the special visitor does not have to visit the household directly, but only if the intended purpose is achieved by accessing the mailbox / courier in the lobby.

Thereafter, the special visitor executes an access application on his terminal 10 (505), touches the special visitor access button in the form of a soft key, and approaches the entrance terminal 20 (506). The authentication information stored in 10) is transmitted to the door terminal 20 based on NFC (507).

Thereafter, the front door terminal 20 only transmits the authentication information received from the terminal 10 of the special visitor to the server 30 (508).

Thereafter, the server 30 only checks the reservation of the special visitor based on the authentication information and the DB 40, and then transmits the check result and the predetermined access approval to the door terminal 20 (509, 510).

Thereafter, when the entrance terminal 20 is reserved (511), check whether the entrance approval (512), if the access is approved to release the locked state (513), if the entrance and exit keeps the locked state (514).

Of course, if not reserved, the door is kept locked.

On the other hand, the method of the present invention as described above can be written in a computer program. And the code and code segments constituting the program can be easily inferred by a computer programmer in the art. In addition, the written program is stored in a computer-readable recording medium (information storage medium), and read and executed by a computer to implement the method of the present invention. The recording medium may include any type of computer readable recording medium.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. The present invention is not limited to the drawings.
