Modes for Carrying Out the Invention

[0010] Modes for carrying out the present disclosure will be described with reference to the accompanying drawings. In each figure, the same or corresponding parts are denoted by the same reference numerals. Redundant descriptions of such parts are appropriately simplified or omitted.

[0011] Embodiment 1. FIG. 1 is a diagram showing an example of an access management system using the mobile terminal 1 in Embodiment 1. The access management system is a system for managing access to a specific location. FIG. 1 shows, as an example of the access management system, an entrance / exit management system for managing access to a specific restricted access area. In the entrance / exit management system, the specific location for managing access is the entrance to the restricted access area. The restricted access area is an area where access is restricted to specific persons only. Hereinafter, a person permitted to access a specific location, that is, a person permitted to enter the restricted access area in this example, is also referred to as a permitted person.

[0012] The entrance / exit management system shown in FIG. 1 includes a mobile terminal 1, an entrance / exit management device 2, an ID controller 3, a server 4, and an electric lock 5.

[0013] As an example, the electric lock 5 is provided on a door for entering and exiting the restricted access area.

[0014] The ID controller 3 controls the electric lock 5. The ID controller 3 also communicates with the entrance / exit management device 2 and the server 4. The entrance / exit management device 2 communicates with the mobile terminal 1 respectively held by users. The mobile terminal 1 is, for example, a smartphone.

[0015] The entrance / exit management device 2 is a device that functions as an access management device for managing access to the entrance of the restricted access area for users. The entrance / exit management device 2 has a function of receiving a personal ID from the mobile terminal 1. The personal ID is information for identifying the user of the mobile terminal 1. The personal ID received by the entrance / exit management device 2 from the mobile terminal 1 is transmitted to the server 4 that performs authentication processing via the ID controller 3. Permitted person information for identifying permitted persons is registered in advance in the server 4.

[0016] At server 4, the personal ID received from ID controller 3 is compared with the permitted person information. If the personal ID matches any of the permitted person information, the personal ID is authenticated. If the personal ID does not match any of the permitted person information, the personal ID is not authenticated. When the personal ID is authenticated at server 4, it is determined that entry into the restricted access area is permitted. That is, when the personal ID is authenticated at server 4, the user of mobile terminal 1 is permitted to enter the restricted access area. When the personal ID is not authenticated at server 4, it is determined that entry into the restricted access area is not permitted. That is, when the personal ID is not authenticated at server 4, the user of mobile terminal 1 is not permitted to enter the restricted access area.

[0017] The result of the determination made at server 4 is sent to ID controller 3. If it is determined at server 4 that entry is permitted for the personal ID, ID controller 3 unlocks the electric lock 5. As a result, the user of mobile terminal 1 can open the door and enter the restricted access area. On the other hand, if it is not determined at server 4 that entry is not permitted for the personal ID, ID controller 3 does not unlock the electric lock 5. That is, the user of mobile terminal 1 cannot enter the restricted access area. The result of the determination made at server 4 is sent to the entry / exit management device 2 via ID controller 3. The entry / exit management device 2 has a function of sending the result to mobile terminal 1 as a response to receiving the personal ID from mobile terminal 1. The result is an example of information indicating whether entry through the entrance to the restricted access area is permitted.

[0018] In this way, the information received by the entry / exit management device 2 from mobile terminal 1 is sent to server 4 that manages the information. Also, server 4 manages the received information. For example, when infection-related information is transmitted to the entry / exit management device 2 from mobile terminal 1 with the information associated with the personal ID, at server 4, the infection-related information and the personal ID are managed in an associated state. The infection-related information is information indicating that the person is an infected person or a close contact person regarding a specific virus. The virus may be COVID-19.

[0019] Therefore, from the perspective of privacy protection, it is preferable that the infection-related information is not transmitted to the entrance / exit management device 2 from the mobile terminal 1 with the personal ID associated therewith. In order to realize such a function, as shown in FIG. 1, if the user of the mobile terminal 1 is an infected person, the personal ID does not need to be transmitted from the mobile terminal 1 to the entrance / exit management device 2. Similarly, if the user of the mobile terminal 1 is a close contact, the personal ID does not need to be transmitted from the mobile terminal 1 to the entrance / exit management device 2. Note that if the user of the mobile terminal 1 is neither an infected person nor a close contact, even if the personal ID is transmitted from the mobile terminal 1 to the entrance / exit management device 2, there is no particular problem from the perspective of privacy protection.

[0020] FIG. 2 is a diagram for explaining the functions of the access control system shown in FIG. 1.

[0021] The mobile terminal 1 includes an input unit 6, a personal ID storage unit 7, an infection-related information storage unit 8, a detection unit 9, a detection information storage unit 10, an infection-related information determination unit 11, an entrance permission determination unit 12, a transmission unit 13, and a reception unit 14.

[0022] Next, the outline of the operation of the mobile terminal 1 in the first embodiment will be described with reference to FIG. 3. FIG. 3 is a flowchart for explaining the outline of the operation of the mobile terminal in the first embodiment.

[0023] In S100, it is determined whether a personal ID has been input to the input unit 6. The user inputs the personal ID from the input unit 6. When the personal ID is input from the input unit 6, it is determined as YES in S100. If the personal ID is not input to the input unit 6 by the user in S100, it is determined as NO in S100. If it is determined as YES in S100, in S101, the personal ID input by the input unit 6 is stored in the personal ID storage unit 7. If it is determined as NO in S100, it is continuously determined in S100 whether a personal ID has been input.

[0024] Next, in S102, it is determined whether infection-related information indicating that the user is an infected person or a close contact has been input to the input unit 6. If the user is an infected person or a close contact, the user inputs the infection-related information from the input unit 6. When the infection-related information is input from the input unit 6, it is determined as YES in S102. If the user is neither an infected person nor a close contact, the user does not input the infection-related information from the input unit 6. If the infection-related information is not input from the input unit 6, it is determined as NO in S102. When it is determined as YES in S102, in S103, the infection-related information storage unit 8 stores the infection-related information input by the input unit. When it is determined as NO in S102, the infection-related information is not stored in the infection-related information storage unit 8, and the process of S104 is performed.

[0025] Next, in S104, it is determined whether the detection unit 9 has detected an approach under specific conditions with another mobile terminal having information indicating that the user is an infected person or a close contact. Another mobile terminal having information indicating that the user is an infected person or a close contact is referred to as mobile terminal 1A. The specific conditions are preset according to time, distance, etc. For example, when the state where mobile terminal 1 exists within 1 m of mobile terminal 1A continues for 15 minutes or more, it is determined as YES. As the communication between mobile terminal 1 and mobile terminal 1A, it is preferable to use short-range wireless communication. Any standard of short-range wireless communication may be adopted.

[0026] When the detection unit 9 has detected an approach under specific conditions with mobile terminal 1A, it is determined as YES in S104. When the detection unit 9 has not detected an approach under specific conditions with mobile terminal 1A, it is determined as NO in S104. When it is determined as YES in S104, in S105, the detection information detected in S104 is stored in the detection information storage unit 10. When it is determined as NO in S104, the detection information is not stored in the detection information storage unit 10, and the process of S106 is performed.

[0027] Also, in the mobile terminal 1, a determination process is performed on whether to transmit the personal ID stored in the personal ID storage unit 7 to the entrance / exit management device 2. This determination process may be started by receiving specific information from the entrance / exit management device 2. This determination process may be started by inputting specific information from the input unit 6. This determination process may be started when other conditions are satisfied.

[0028] For example, in S106, it is determined whether infection-related information is stored in the infection-related information storage unit 8. If the infection-related information is stored in the infection-related information storage unit 8, it is determined as YES in S106. If the infection-related information is not stored in the infection-related information storage unit 8, it is determined as NO in S106.

[0029] When it is determined as YES in S106, in S107, the infection-related information determination unit 11 determines that the user is an infected person or a close contact. Next, in S108, the entrance / exit permission determination unit 12 determines that it is not necessary to transmit the personal ID to the entrance / exit management device 2. In S109, the transmission unit 13 does not transmit the personal ID to the entrance / exit management device 2.

[0030] When it is determined as NO in S106, in S110, it is determined whether detection information is stored in the detection information storage unit 10. If the detection information is stored in the detection information storage unit 10, it is determined as YES in S110. If the detection information is not stored in the detection information storage unit 10, it is determined as NO in S110.

[0031] When it is determined as YES in S110, the same operations as when it is determined as YES in S106 are performed. Specifically, the operations from S107 to S109 are performed.

[0032] When it is determined as NO in S110, in S111, the infection-related information determination unit 11 determines that the user is not an infected person or a close contact. Next, in S112, the entrance / exit permission determination unit 12 determines that it is necessary to transmit the personal ID to the entrance / exit management device 2. In S114, the transmission unit 13 transmits the personal ID to the entrance / exit management device 2.

[0033] In S114, the receiving unit 14 determines whether it has received the admission permission result to the restricted access area from the access control device 2 as a response to the personal ID transmitted from the transmitting unit 13 to the access control device. If the receiving unit 14 has received the admission permission result to the restricted access area from the access control device 2, it is determined as YES. If the receiving unit 14 has not received the admission permission result to the restricted access area from the access control device 2, it is determined as NO. If it is determined as NO in S114, it continues to determine whether the admission permission result to the restricted access area has been received from the access control device 2. The admission permission result received by the receiving unit 14 is displayed, for example, on the display of the mobile terminal 1.

[0034] As the communication between the mobile terminal 1 and the access control device 2, it is preferable to use short-range wireless communication. Any standard of short-range wireless communication may be adopted.

[0035] Note that the mobile terminal 1 may not include the detection unit 9 and the detection information storage unit 10. In such a case, the processes shown in S104 and S105 in FIG. 3 are not performed. Also, the process shown in S110 is not performed. When it is determined as NO in S106, the process shown in S111 is performed. That is, if the infection-related information is not stored in the infection-related information storage unit 8, the transmitting unit 13 transmits the personal ID stored in the personal ID storage unit 7 to the access control device 2 in S113.

[0036] Note that the mobile terminal 1 does not have to perform the operation of S114.

[0037] According to the first embodiment described above, the mobile terminal 1 determines whether the user is an infected person or a close contact, and if the user is an infected person or a close contact, does not transmit the personal ID to the access control device 2. Therefore, it is possible to prevent information indicating that the user is an infected person or a close contact from being transmitted to the access control device 2 in association with the personal ID from the mobile terminal 1. It is possible to prevent the infection-related information and the personal ID from being managed in a linked state in the server 4, and it is possible to strengthen the protection of privacy in the access control system.

[0038] In the example shown in this embodiment, if neither the infection-related information nor the detection information is stored, the personal ID is transmitted from the mobile terminal 1 to the entrance / exit management device 2. Therefore, the convenience of the user and the security of the system are not reduced. In addition, since it is possible to restrict the passage of users who are highly likely to be infected or close contacts, the occurrence of infection clusters can also be suppressed.

[0039] Next, an example of the hardware constituting the mobile terminal 1 will be described with reference to FIG. 4. FIG. 4 is a hardware configuration diagram of the mobile terminal 1 in Embodiment 1.

[0040] The mobile terminal 1 includes a processing circuit 100 including a processor 100a and a memory 100b as hardware resources. The processing circuit 100 may include a plurality of processors 100a. The processing circuit 100 may include a plurality of memories 100b. The processing circuit 100 may include dedicated hardware 200. The processing circuit 100 may include a plurality of dedicated hardware 200.

[0041] For example, each function of the mobile terminal 1 is realized by the processing circuit 100 respectively. For example, each function of the mobile terminal 1 is realized by the processing circuit 100 collectively. The processing circuit 100 includes a processor 100a and a memory 100b, but may not include dedicated hardware 200.

[0042] When the processing circuit 100 includes a processor 100a and a memory 100b, each function of the mobile terminal 1 is realized by software, firmware, or a combination of software and firmware. Software and firmware are described as programs. Software and firmware are stored in the memory 100b. The processor 100a reads and executes the program stored in the memory 100b to realize each function of the mobile terminal 1.

[0043] Processor 100a is also referred to as a CPU (Central Processing Unit), a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, or a DSP. For example, memory 100b is a non-volatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, or an EEPROM, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, or a DVD.

[0044] When processing circuit 100 includes dedicated hardware 200, processing circuit 100 is implemented by, for example, a single circuit, a composite circuit, a programmed processor, a parallel-programmed processor, an ASIC, an FPGA, or a combination thereof.

[0045] Regarding each function of the mobile terminal 1, a part may be implemented by dedicated hardware 200 and the other part may be implemented by software or firmware. For example, the function of transmitting the personal ID to the entrance / exit management device 2 may be implemented by the processing circuit 100 as dedicated hardware, and the functions other than the function of transmitting the personal ID to the entrance / exit management device 2 may be implemented by the processor 100a reading and executing a program stored in the memory 100b.

[0046] In this way, processing circuit 100 realizes each function of mobile terminal 1 with hardware 200, software, firmware, or a combination thereof.

[0047] Although not shown, each function of the entrance / exit management device 2 is also realized by a processing circuit equivalent to the processing circuit 100 that realizes each function of the mobile terminal 1.

[0048] Although not shown, each function of the ID controller 3 is also realized by a processing circuit equivalent to the processing circuit 100 that realizes each function of the mobile terminal 1.

[0049] Although not shown, each function of the server 4 is also realized by a processing circuit equivalent to the processing circuit 100 that realizes each function of the mobile terminal 1.

[0050] Embodiment 2 FIG. 5 is a diagram showing the configuration of the access control system in Embodiment 2. Note that the same reference numerals are given to the same or corresponding parts as those in Embodiment 1, and the description thereof is omitted.

[0051] In Embodiment 2, the mobile terminal 1 further includes an authentication unit 15.

[0052] Next, the outline of the operation of the mobile terminal 1 in Embodiment 2 will be described with reference to FIG. 6. FIG. 6 is a flowchart for explaining the outline of the operation of the mobile terminal in Embodiment 2.

[0053] The processes shown from S200 to S203 in FIG. 6 are the same as the processes shown from S100 to S103 in FIG. 3. For example, in S201, the personal ID input from the input unit 6 is stored in the personal ID storage unit 7. When infection-related information is input from the input unit 6, in S203, the infection-related information is stored in the infection-related information storage unit 8.

[0054] In addition, in the mobile terminal 1, an authentication process by the authentication unit 15 and a determination process as to whether to transmit the admission permission result by the admission permission determination unit 12 to the entrance / exit management device 2 are performed. The authentication process and the determination process may be started by receiving specific information from the entrance / exit management device 2. The authentication process and the determination process may be started by inputting specific information from the input unit 6. The authentication process and the determination process may be started when other conditions are satisfied.

[0055] For example, in S204, the receiving unit 14 determines whether the permitted person information has been received from the entrance / exit management device 2. As an example, the entrance / exit management device 2 transmits the permitted person information to the mobile terminals existing within a specific range. The entrance / exit management device 2 may transmit the permitted person information to the mobile terminal that has sent a specific request.

[0056] When the receiving unit 14 receives the permittee information from the entry / exit management device 2, it determines YES. When the receiving unit 14 does not receive the permittee information from the entry / exit management device 2, it determines NO. If it is determined NO in S204, the receiving unit 14 continues to determine whether it has received the permittee information from the entry / exit management device 2. In S205, the authentication unit 15 authenticates the personal ID stored in the personal ID storage unit 7 based on the permittee information received by the receiving unit 14.

[0057] For example, if the personal ID matches any of the permittee information, the personal ID is authenticated. In such a case, the authentication result by the authentication unit 15 is successful authentication. If the personal ID does not match any of the permittee information, the personal ID is not authenticated. In such a case, the authentication result by the authentication unit 15 is authentication failure.

[0058] In S206, the entry permission determination unit 12 determines whether the authentication unit 15 has authenticated the personal ID in S205. If the personal ID is authenticated by the authentication unit 15, it is determined YES in S206. If the personal ID is not authenticated by the authentication unit 15, it is determined NO in S206.

[0059] If it is determined NO in S206, in S207, the entry permission determination unit determines that entry to the restricted entry area is not allowed. If it is determined YES in S206, in S208, the entry permission determination unit determines that entry to the restricted entry area is allowed.

[0060] Next, in S209, it is determined whether the detection unit 9 has detected an approach under specific conditions with the mobile terminal 1A. The detection method is the same as in the first embodiment. If the detection unit 9 has detected an approach under specific conditions with the mobile terminal 1A, it is determined YES in S209. If the detection unit 9 has not detected an approach under specific conditions with the mobile terminal 1A, it is determined NO in S209. If it is determined YES in S209, in S210, the detection information detected in S209 is stored in the detection information storage unit 10. If it is determined NO in S209, the detection information is not stored in the detection information storage unit 10, and the process of S211 is performed.

[0061] Next, at S211, it is determined whether infection-related information is stored in the infection-related information storage unit 8. If the infection-related information is stored in the infection-related information storage unit 8, it is determined as YES. If the infection-related information is not stored in the infection-related information storage unit 8, it is determined as NO.

[0062] If it is determined as YES at S211, at S212, the infection-related information determination unit 11 determines that the user is an infected person or a close contact. Next, at S213, the entrance / exit permission determination unit 12 determines that it is unnecessary to transmit the personal ID and the entrance / exit permission result by the infection-related information determination unit 11 to the entrance / exit management device 2. At S214, the transmission unit 13 does not transmit the personal ID and the entrance / exit permission result by the infection-related information determination unit 11 to the entrance / exit management device 2.

[0063] If it is determined as NO at S211, at S215, it is determined whether detection information is stored in the detection information storage unit 10. If the detection information is stored in the detection information storage unit 10, it is determined as YES. If the detection information is not stored in the detection information storage unit 10, it is determined as NO.

[0064] If it is determined as YES at S215, the same operations as when it is determined as YES at S211 are performed. Specifically, the operations from S212 to S214 are performed.

[0065] If it is determined as NO at S215, at S216, the infection-related information determination unit 11 determines that the user is not an infected person or a close contact. Next, at S217, the entrance / exit permission determination unit 12 determines that it is necessary to transmit the personal ID and the entrance / exit permission result by the entrance / exit permission determination unit 12 to the entrance / exit management device 2. At S218, the transmission unit 13 transmits the personal ID and the entrance / exit permission result by the entrance / exit permission determination unit 12 to the entrance / exit management device 2.

[0066] Note that the entry / exit management device 2 transmits the information received from the mobile terminal 1 to the server 4 via the ID controller 3. The information from the mobile terminal 1 is managed by the server 4. Also, if the entry permission result received by the entry / exit management device 2 from the mobile terminal 1 is "entry permitted", the ID controller 3 unlocks the electric lock 5.

[0067] Also in the example shown in this embodiment, the mobile terminal 1 does not necessarily need to include the detection unit 9 and the detection information storage unit 10. In such a case, the processes shown in S209 and S210 in FIG. 6 are not performed. Also, the process shown in S215 in FIG. 6 is not performed. When it is determined as NO in S211, the process shown in S216 is performed. That is, if the infection-related information is not stored in the infection-related information storage unit 8, the transmission unit 13 transmits the personal ID stored in the personal ID storage unit 7 and the entry permission result in the entry permission determination unit 12 to the entry / exit management device 2 in S218.

[0068] In this embodiment, an example has been described in which in S218, the transmission unit 13 transmits both the personal ID and the entry permission result in the entry permission determination unit 12 to the entry / exit management device 2. The transmission unit 13 may transmit the authentication result by the authentication unit 15 to the entry / exit management device 2 without transmitting the personal ID in S218.

[0069] Note that when it is determined as YES in S206, only the personal ID may be transmitted in S218. Also, when it is determined as NO in S206, it is not necessary to transmit the personal ID and the entry permission result in the entry permission determination unit 12.

[0070] Note that when it is determined as YES in S206, only the entry permission result in the entry permission determination unit 12 may be transmitted in S218.

[0071] In this embodiment, an example has been described in which the admission determination unit 12 determines that it is necessary to transmit information to the entry / exit management device 2 in S218 regardless of whether the admission determination result in the admission determination unit 12 is admissible or not. The admission determination unit 12 may determine in S218 that it is not necessary to transmit information to the entry / exit management device 2 when the admission determination result in the admission determination unit 12 is not admissible. In such a case, if the admission determination result in the admission determination unit 12 is not admissible, the transmission unit 13 does not transmit the personal ID and the admission determination result to the entry / exit management device 2 even if it is determined as No in S215. That is, when it is determined as NO in S206, it is not always necessary to transmit the admission determination result in the admission determination unit 12.

[0072] Even in the example shown in this embodiment, the same effects as those described in the first embodiment can be achieved. Furthermore, in the example shown in this embodiment, the mobile terminal 1 performs the authentication process of the personal ID. Therefore, the load on the server 4 can be reduced.

[0073] Note that when it is determined as YES in S206, only the personal ID may be transmitted in S218. Also, when it is determined as NO in S206, it may not be necessary to transmit the personal ID and the admission determination result in the admission determination unit 12. Even in this case, since the personal ID corresponding to the infected person and the close contact is not transmitted, the same effect is achieved.

[0074] Note that when it is determined as YES in S206, only the admission determination result in the admission determination unit 12 may be transmitted in S218. Even in this case, since the personal ID corresponding to the infected person and the close contact is not transmitted, the same effect is achieved.

[0075] Note that when it is determined as NO in S206, it is not always necessary to transmit the admission availability result in the admission availability determination unit 12. When a result indicating non-admission to the restricted access area is transmitted, by artificially associating the personal ID of the user with the result indicating non-admission to the restricted access area, it may become personal information indicating that the user is an infected person or a close contact. When it is determined that entry to the restricted access area is not allowed, privacy can be further protected by not transmitting the result to that effect.
