Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a system, method, and program for authenticating a person who enters or exits an area (including a site, facility, building, etc.) belonging to an organization.
[0002]
[Prior art]
In general, a person who wants to enter a domain belonging to an organization such as a company clearly indicates his / her identity and obtains the company's permission by showing the matter such as “who is who”. Need. As a method for clearly showing one's own identity, for example, there is a method in which necessary information such as a name and an organization to which the user belongs is entered on a predetermined form at the time of introduction. In addition, when it is scheduled to frequently come and go in such areas, there is a method in which those matters are sent in advance to the company side by mail or other communication methods and registered in the company side.
[0003]
However, it is not only troublesome to fill in items for authenticating one's identity at the time of introduction, but there is a problem that it takes a lot of time to authenticate beginners. In particular, for those who frequently enter and exit the facility, it is necessary to perform the same procedure every time when entering the facility, and this method is not advantageous from the viewpoint of efficient entrance and exit management. On the other hand, the latter method can shorten the time required to fill in the necessary information at the beginning, but it still takes a long time to verify and authenticate the items that are performed after that. There is concern.
[0004]
In addition, information obtained about the introductory person is often registered in a database. This is because, based on the information registered in the database, for example, statistical data relating to beginners can be created, and management and operation of entrance / exit can be studied at a later date. However, since data input to the database is performed manually, it takes time and effort, but there is a problem that input errors are likely to occur.
[0005]
Regardless of which method is used, if a predetermined item necessary for authentication is leaked, there is a concern that an illegal introduction by so-called “spoofing” may be performed. The above problems tend to become more serious as the organization becomes larger, such as a corporate organization.
[0006]
Note that user information such as biometric information is stored in the server in advance, and the input information is compared with the information stored in the server for the user who has input biometric information at a later date. This is disclosed in Patent Document 1. This belongs to a technical field different from the present application. However, if such a technique is applied to entry / exit management, information verification itself can be accurately performed by a server. However, there is no change in that an introductory person must input information (biometric information etc.) necessary for authentication at the time of introductory, for example, it will take time and effort at the time of input. In addition, this type of signal processing is generally complicated unlike collation of numbers, symbols, characters, etc., and is disadvantageous from the viewpoint of easily constructing a system.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows an overall view of an entrance / exit management system according to an embodiment of the present invention. The entrance / exit management system 100 determines whether the user of the mobile terminal 102 is allowed to enter or exit from an area belonging to a certain organization such as a corporate organization. For simplicity, the following description assumes that a user of a mobile terminal visits a certain company. However, the present invention is not limited to such a specific application, and is applied to various entrance and exit management. Is possible.
[0012]
The mobile terminal 102 is a mobile phone, for example, and has an infrared communication function in addition to being able to perform telephone communication. In addition, the mobile terminal 102 has a platform necessary for executing an entrance / exit program described later, which is realized as, for example, a JAVA (registered trademark) application. In FIG. 1, an infrared light receiving unit 104 that receives an infrared signal from the mobile terminal 102 is depicted. The infrared light receiving unit 104 is connected to the client terminal 108 through a serial connection unit 106 such as an RS232C cable. The serial connection unit 106 only needs to be able to transmit the signal received by the infrared light receiving unit 104 to the client terminal 106. For example, instead of the RS232C cable, RS422, USB (Universal Serial Bus), IEEE 1394, IrDA (InfraredData) It is also possible to use a transmission medium that conforms to a standard such as Association. However, it is desirable to use an RS232C cable from the viewpoint of versatility and cost of the member. Further, the client terminal 108 is connected to the server 110 by a local area network. Signal transmission between the client terminal 108 and the server 110 is based on TCP / IP (Transmission Control Protocol / Internet Protocol).
[0013]
FIG. 1 also shows a designated site 114 connected to a public network 112 such as the Internet network. The mobile terminal 102 that has accessed the designated site 114 while satisfying certain conditions can download the entrance / exit program from there. The entrance / exit program is a program that is stored in the designated site 114 and needs to be executed when entering or exiting a corporate facility. A company that manages entrance / exit stores an entrance / exit program in the server 114 in advance. Access to the server 114 can be executed by accessing a website of the company, for example.
[0014]
The infrared light receiving unit 104 and the client terminal 108 included in the “authentication unit” are provided at the entrance or exit of a facility where entrance and exit management is performed. In this embodiment, the server 110 is provided at a location away from the client terminal 108. However, it is also possible to construct a system with the client terminal 108 and the server 110 as an integrated device, or to arrange them close to each other. However, from the viewpoint of performing processing for people entering and exiting by providing a plurality of infrared light receiving units (although only one is illustrated in FIG. 1), the client terminal 108 and the server as in this embodiment 110 is provided separately, and it is desirable to provide a plurality of client terminals 108 (and the infrared light receiving unit 102) in one server 110. Further, although the infrared light receiving unit 104 and the client terminal 108 are drawn separately, the infrared light receiving unit 104 can be integrated into the client terminal 108 as a single unit.
[0015]
The operation will be described next. For simplicity, it is assumed that the user U of the mobile terminal visits the company A that performs entrance / exit management according to the present embodiment and finishes the desired work with the employees of the company A, and then starts the company A. Further, the user U is scheduled to visit the company A many times, not just once. First, the user U gives predetermined information to the company A. This predetermined information includes the user's name, organization name (company name, office name, institution name, etc.), mobile terminal manufacturing number, mobile terminal phone number, and user's face photo (photo of the face). However, it is also possible to include other information instead of or in addition to these. When the company A receives the predetermined information, the predetermined information is stored in the server 110 of the company A. Then, the introductory serial number set by the company A, the password, and the URL (Uniform Resource Locator) of the designated site 114 are notified to the user A. Also, the designated site 114 is notified of the beginner serial number and password. In the present embodiment, the server 110 and the designated site 114 are drawn separately, but they can also be provided in the same hardware, for example.
[0016]
FIG. 2 shows a flowchart of a procedure performed between the user U (the mobile terminal) and the designated site 114. In order for the user U to enter the company A, it is necessary to start the entrance / exit program at the entrance of the company A. Therefore, before the user U visits the company A, the user U needs to download the entrance / exit program to the mobile terminal. This mobile terminal has a telephone number and a serial number included in the predetermined information.
[0017]
As shown in step 202, the user U accesses the designated site 114 through his / her mobile terminal using the URL notified from the company A. It is possible to make this URL the same as the URL of the website of the company A and reach the designated site 114 through a link. It is also possible for the URL notified to the user U to directly designate the designated site 114. When accessing the designated site 114, the user U of the mobile terminal inputs the introductory serial number and password.
[0018]
As shown in step 204, the designated site 114 collates the input information and determines its suitability.
[0019]
As shown in step 206, if the input information is appropriate, the entrance / exit program is distributed to the mobile terminal (ie, the mobile terminal downloads the entrance / exit program).
[0020]
FIG. 3 shows a flowchart of introductory management according to the present embodiment. It is assumed that the user U has arrived at the entrance of the company A. First, as shown in step 302, the entrance / exit program is started on the mobile terminal. Accordingly, the mobile terminal waits for an intention to enter the company A or to exit from the company A. More specifically, for example, an “entry” button and an “exit” button are displayed on the display screen 103 of the mobile terminal, and the user U selects a desired one by pressing a predetermined key of the mobile terminal. In the current case, “Getting Started” is selected.
[0021]
As shown in step 304, in response to the intention to “get started”, the mobile terminal wirelessly transmits an infrared signal including predetermined authentication information. In this case, the user U needs to make an infrared transmitter (not shown) of the mobile terminal 102 face the infrared receiver 104. In the present embodiment, it is assumed that the distance between the mobile terminal 102 and the infrared light receiving unit 104 in this case is within a range of 30 cm or less, but it is possible to increase the distance as necessary. It is. The predetermined authentication information includes the first authentication information (introductory serial number and password) set on the company A side and the second authentication information set separately from the company A (manufacturing number and telephone number of the mobile terminal). ) And
[0022]
As shown in step 306, the infrared light receiving unit 104 that has received the infrared signal performs protocol conversion for transmitting the content of the infrared signal in a signal format conforming to the RS232C standard.
[0023]
As shown in step 308, the converted signal is transmitted to the client terminal 108.
[0024]
As shown in step 310, the client terminal 108 performs protocol conversion for transmitting the received signal in a signal format compliant with TCP / IP.
[0025]
As shown in step 312, the client terminal 108 transmits the converted signal to the server 110 through a local area network (LAN) in the enterprise.
[0026]
In step 314, the server 110 that has received the signal from the client terminal 108 extracts the predetermined authentication information from the signal. The server 110 collates the extracted information with registered information already stored in the server 110. The contents of the registration information are received from the user U before the company A side gives the introductory serial number and password to the user U (provided that this information is received, a password or the like is given to the user U) Has been). As described above, the information to be collated includes the first authentication information set on the company A side (the introductory serial number and password), and the information unique to the mobile terminal set separately from the company A. 2 authentication information (manufacture number and telephone number of the mobile terminal). If all of these pieces of information do not match the registration information in the server 110, the introduction of the user U is rejected and the client terminal 108 is notified accordingly. When all the information received from the mobile terminal of the user U matches the registration information in the server 110, the user U is permitted to enter.
[0027]
As shown in step 316, when the user U is permitted to enter, image data regarding the face of the user U is transmitted to the client terminal 108.
[0028]
As shown in step 318, when the user U is permitted to enter, the image data is displayed on the display of the client terminal 108. By confirming the displayed image and the user U in the vicinity of the infrared light receiving unit 104 by a monitor on the company A side, the user U is finally permitted to enter the site.
[0029]
According to the present embodiment, the authentication information necessary for user authentication is created and transmitted as a predetermined infrared signal simply by displaying the intention of “Getting Started” after the entry / exit program is started (step 304). . The program downloaded by the mobile terminal in step 206 in FIG. 2 is set to transmit information specific to the mobile terminal (starter serial number, password, telephone number, and manufacturing number). Which program is to be downloaded can be distinguished by an introductory serial number and password. Therefore, when the user U is introduced, there is no need for the user U to write information necessary for authentication on paper or to present it to a monitor, so that work efficiency related to authentication at the time of introduction is improved. Furthermore, since it is not necessary to present information necessary for authentication to anyone in the vicinity, even if the screen of the mobile terminal is stolen by another person, there is no possibility that information necessary for authentication leaks on the spot.
[0030]
Further, when authenticating the user U in the server 110, the first authentication information (introductory serial number and password) set on the company A side and the second authentication specific to the mobile terminal set separately from the company A Two types of information of information (mobile terminal manufacturing number and telephone number) are collated. The contents to be collated are not set unilaterally on the company A side, but are determined only after the first authentication information set on the company side and the second authentication information specific to the user are combined. is there. Therefore, even if only one information is leaked, the collation result is negative if there is no other information. If a person who illegally obtained both pieces of information sends the information to the server 110, the collation result performed by the server 110 may be affirmative, but the display on the client terminal 108 Since it is clear that the displayed image data belongs to another person, it is possible to prevent the person from entering the company.
[0031]
The second authentication information is a production number and a telephone number unique to the mobile terminal. However, the second authentication information may be a number or password arbitrarily set on the user U side. This is because both the first and second authentication information are stored in advance in the server 110, and it is possible to determine whether the entry is permitted or not by comparing them at the beginning. However, if the production number is included in the authentication item, for example, when the user U enters, after the introduction, or at the departure, the production number described in the mobile terminal and the production number registered in the server 110 It becomes possible to perform a stricter check by comparing with. From such a viewpoint of performing authentication using the production number, the mobile terminal does not have to be a mobile phone, and can be an information terminal (for example, a notebook computer) having an infrared communication function. . However, if the telephone number of the mobile terminal carried by the user U is used (if it is included in the authentication item), for example, by calling the telephone number after the introduction of the user U, the call of the introductory person can be made. In addition to being possible, it is also possible to confirm the identity and the like of the person carrying the mobile terminal and the user U.
[0032]
When purchasing a mobile terminal such as a mobile phone, some kind of identification is made to confirm the identity. In other words, the possession of a mobile terminal to which a telephone number is assigned has some form of identification for that person. For those who can use the mobile terminal uniquely specified by the production number and the telephone number, at least some identification is made. It is advantageous to check the telephone number and the serial number in that this point can be taken into account in the entrance / exit determination.
[0033]
FIG. 4 shows a flowchart of exit management according to the present embodiment. In this flowchart, it is assumed that the user U of the mobile terminal that has entered the company A has completed a predetermined task such as having a meeting with the employee B of the company A, and then starts the company A. A user U who is authorized to enter Company A can meet an employee B of Company A. On the other hand, after the predetermined infrared information is transmitted from the mobile terminal 102 to the infrared light receiving unit 104, the entrance / exit program operates the mobile terminal 102 so as to wait for the input of the employee number of the employee of the company A. More specifically, for example, a blank field for inputting an employee number at the start of work is displayed on the display of the mobile terminal 102.
[0034]
As shown in step 402, the employee B who performs a predetermined job or work with the user U inputs the employee number of the employee B in the field. In this case, it is necessary to consider that the employee number of the employee B is not known to the user U. That is, the employee B inputs the employee number. Note that if the user U does not need to meet the employee of the company A after the introduction (for example, simple maintenance of the device, etc.), for example, the monitoring person at the client terminal 108 sets the given identification number. It is possible to input. The entrance / exit program operates the mobile terminal 102 so as to wait for input of the employee number of the employee at the end of the work after the employee number at the start of the work is input. More specifically, for example, a blank field for inputting the employee number at the end of the work is displayed on the display of the mobile terminal 102.
[0035]
As shown in step 404, when the predetermined work between the user U and the employee B is completed, the employee B inputs the employee number of the employee B to the user U's mobile terminal again. The input in this case also needs to be performed secretly. As in the case of the start of work, when the work performed by the user U does not need to meet the employee of the company A after the introduction, for example, a monitor at the client terminal 108 inputs a given identification number. Is possible. Thereafter, the entrance / exit program operates the mobile terminal 102 so as to display the intention of whether or not to enter the company A. More specifically, a screen displaying “Getting In” and “Getting Out” buttons as displayed immediately before step 304 in FIG. 3 is displayed on the display of the mobile terminal. In the current case, “Exit” will be selected. At this time, the user U needs to be located in the vicinity of the infrared light receiving unit provided at the exit of the company A. When the entrance and exit of the company A are different, it is necessary that an infrared light receiving unit and a client terminal as shown in FIG.
[0036]
As shown in step 406, in response to the user U's intention to “get out”, the mobile terminal transmits an infrared signal having predetermined authentication information to the infrared light receiving unit 104 (as much as possible). The transmitter of the mobile terminal 102 is approaching the infrared light receiver 104). In this case, the predetermined authentication information includes, in addition to the information transmitted at step 304 in FIG. 3, the employee number input at step 402 and the time when it was input, the employee number input at step 404 and Including the entered time.
[0037]
In step 408, protocol conversion from an infrared signal to a signal compliant with RS232C is performed, and in step 410, the converted signal is transmitted to the client terminal 108.
[0038]
In step 412, the signal received by the client terminal 108 is converted into a signal compliant with TCP / IP, and the converted signal is transmitted to the server 110 in step 414.
[0039]
In step 416, in addition to the same collation as in step 314 of FIG. 3, the employee number input in steps 402 and 404 is inspected. This inspection is to determine whether the employee number corresponds to the employee number assigned to the employee in company A or whether the conditions to be satisfied by the employee number in company A are satisfied. is there. The former is based on a comparison of the employee numbers of all existing employees and the received employee numbers. This is a straightforward approach, but it is extremely disadvantageous when the number of employees is large. The latter is a condition that the employee number must satisfy, such as “the employee number is 7 digits”, “the employee number starts with an alphabet”, and “the employee number contains 4 or more digits”. It is inspected whether or not it is met. This makes it possible to determine the suitability of the employee number very simply. If the employee number is inappropriate, the client terminal 108 is notified to that effect and refuses to enter.
[0040]
If the employee number is appropriate as shown in step 418, the image data for the user U is notified to the client terminal 108, and the image data is displayed on the display of the client terminal 108 as shown in step 420. Is displayed. By confirming this image and the user U, the user U is finally permitted to enter. On the other hand, the information regarding the employee number input in steps 402 and 404 and the time when it was input is stored in the server 110. As a result, all data such as introductory, introductory, and visiting destinations (partners to visit) of the user U are automatically recorded in the server 110, and a highly accurate database that is less affected by human input errors is easily constructed. It becomes possible.
[0041]
In this embodiment, an employee number is input, but any number, symbol or combination thereof (personal identification number) that can identify an employee can be used. For example, when an employee number is clearly indicated on an employee badge carried by the employee, it is desirable to use an identification number other than the employee number. Also, setting the personal identification number to be limited to that day is advantageous in that it allows the user U to perform input operations in steps 402 and 404 in FIG. This is because the personal identification number in this case does not need to be secret.
[0042]
As described above, according to the embodiment of the present application, it is possible to appropriately authenticate a person who enters or exits an area belonging to a certain organization. Furthermore, according to the present embodiment, since the entrance / exit program that consistently performs the procedure from entry to exit is used, the user's work at the start, the user's work at the start, at the start and at the start This makes it possible to perform the work of the monitoring personnel very efficiently. In addition, it is possible to easily construct a highly accurate database that is less affected by human input errors.
[0043]
According to the embodiment of the present application, when the user's introduction or exit is permitted, image data relating to the user's face is displayed, so that intruders who have illegally obtained information necessary for authentication such as passwords can be prevented. Is possible.
[0044]
According to the embodiment of the present application, since the client terminal and the server are provided separately, for example, a plurality of client terminals and an infrared light receiving unit are prepared, and the authentication work is executed in parallel for people entering and leaving, thereby improving work efficiency. It becomes possible to improve.
[0045]
According to the present embodiment, each node can be connected using a transmission medium compliant with RS232C or TCP / IP, so that a system can be constructed easily and inexpensively.
