Description

  The present invention relates to a contactless communication device, and more particularly to a contactless communication device that performs contactless communication with an information access device, a contactless communication system, a processing method therefor, and a program that causes a computer to execute the method.

  A non-contact communication device such as an IC card that communicates with an information access device such as an R / W (Reader and Writer) device by a non-contact communication method is widely used. The non-contact communication device includes a storage unit for storing information, and transmits the stored information to the R / W device or rewrites and stores the information based on an instruction from the R / W device. .

  Further, a non-contact communication device that manages information stored in a storage unit in units of folders by a hierarchical structure has been proposed. As a non-contact communication apparatus that manages information by this hierarchical structure, for example, a non-contact communication apparatus that enhances security by associating a key with a folder in each hierarchy has been proposed (for example, see Patent Document 1). In this non-contact communication device, in order for the information access device to access the information stored in the folder, for example, authentication is performed using a key associated with a folder in an upper layer, and authentication is performed in order from the upper layer. It is necessary to access the lower hierarchy while receiving.

[Data structure of EEPROM]
FIG. 5 is a diagram showing a data structure example of the EEPROM 144 in the first embodiment of the present invention. The EEPROM 144 stores each information in association with a plurality of nodes having a hierarchical structure. This hierarchical structure is a hierarchical structure in which a plurality of nodes (folders) belong to a lower hierarchy of the highest hierarchy node (root folder).

  Here, the root folder 501 is system definition information that defines the entire system that manages this hierarchical structure. Folders 502 to 507 are area definition information that defines areas managed by each folder. An area is a conceptual area that comprehensively indicates lower-level nodes managed by folders. A file belongs to a folder. This file includes service definition information and a user block. The service definition information is information that defines a key for accessing a corresponding user block, the number of blocks of the corresponding user block, and the like. The user block is composed of, for example, 16 bytes per block, and stores various information such as electronic money information.

  Specifically, the folder 502 belongs to the lower hierarchy of the highest root folder 501, and the folders 503 to 505 belong to the lower hierarchy of the folder 502. Further, the folder 506 belongs to the lower hierarchy of the folder 503, and the folder 507 belongs to the lower hierarchy of the folder 504. Further, the file 580 belongs to the lower hierarchy of the folder 506, the file 581 belongs to the folder 507, and the file 582 belongs to the folder 505. For example, the file 580 belonging to the folder 506 includes service definition information 511 and user blocks 551 to 553.

  Here, for example, the area managed by the folder 503 is an area corresponding to the folder 506 belonging to the folder 503 and the file 580 belonging to the folder 506, and this is defined as an operator A area 561. Similarly, an area managed by the folder 504 is defined as a business operator B area 562, and an area managed by the folder 505 is defined as a business operator C area 563.

  Each node is associated with a unique key (for example, keys 521 to 530). For example, a key 521 is associated with the root folder 501, and a key 522 is associated with the folder 502. In each key shown in FIG. 5, identification information indicating a corresponding node is shown in parentheses. The key associated with each node is used for authentication when each node or a node belonging to a lower hierarchy of each node is accessed. For example, when the file 580 is accessed, authentication using the key 528 associated with the service definition information 511 included in the file 580 is performed. Then, information stored in the user blocks 551 to 553 belonging to the file 580 is read, or new information is written to the user blocks 551 to 553.

  Note that when the R / W devices 200 to 202 access a file belonging to a certain folder, for example, the R / W devices 200 to 202 have all the keys associated with the file and the keys associated with the upper-level folder. It can be. However, for example, as long as it has a key associated with the file, the file may be accessible even if it does not have all the keys associated with the upper-level folder. For example, it can be conditional on having a key associated with the file and a key associated with a preset upper-level folder. In the first embodiment of the present invention, it is possible to access a file on the condition that all the keys associated with the file to be accessed and the keys associated with the upper layer folder are provided. A case will be described as an example.

  For example, the case where the R / W device 200 accesses the file 580 will be described as an example. Assume that the R / W device 200 has a common key (key 521, keys 522 to 523, 526, and 528) for authenticating the root folder 501, folders 502, 503, and 506, and the file 580. In order for the R / W device 200 to access the service definition information 511, first, the root folder 501 is authenticated with the key 521. Next, the folder 502 is authenticated with the key 522, the folder 503 is authenticated with the key 523, and the folder 506 is authenticated with the key 526. In this way, authentication is performed with the key associated with the folder from the upper layer to the lower layer in order, and finally, the file 580 is authenticated with the key 528, and the R / W device 200 receives the file. 580 is accessed.

  Thus, keys are associated with each node (folder and file) as necessary. Since each R / W device 200 to 202 has a common key associated with the node assigned to each business operator, access to the files 580 to 582 stored in the EEPROM 144 is R / W. Limited to each device 200-202. For example, as shown in FIG. 5, the business operator A having the R / W device 200 can be set to be accessible only within the business operator A area 561. Similarly, the business operator B having the R / W device 201 can be set to be accessible only within the business operator B area 562. Further, the business operator C having the R / W device 202 can be set to be accessible only within the business operator C area 563.

  For example, reference information or availability information is associated with the highest hierarchy (that is, the folder 503, the folder 504, and the folder 505) belonging to the operator area assigned to each operator. For example, as shown in FIG. 5, permission information 541 is associated with a folder 503, reference information 532 is associated with a folder 504, and reference information 533 is associated with a folder 505.

  The availability information stores information indicating whether access is allowed when there is an access request to a node associated with the availability information or a file belonging to a lower hierarchy than the node. Specifically, “permitted” indicating accessible or “not permitted” indicating inaccessible is stored in the availability information. When “No” is stored in the permission information associated with a certain folder, it is not possible to access the folder and the file belonging to the lower hierarchy. On the other hand, if “permitted” is stored in the permission information of a certain folder, it is possible to access the folder and the file belonging to the lower hierarchy. For example, as illustrated in FIG. 5, when “permitted” is stored in the permission information 541 associated with the folder 503, the R / W device (operator A) 200 can access the service definition information 511. is there.

  The reference information stores identification information given to a node other than the node with which the reference information is associated. For example, as illustrated in FIG. 5, identification information “area # 1000” of the folder 503 is stored in the reference information 532 associated with the folder 504. The reference information 533 associated with the folder 505 stores the identification information “area # 2000” of the folder 504. Note that it is assumed that either the availability information or the reference information is associated with the folder specified by the identification information stored in the reference information.

  For example, when there is an access request to a folder associated with the reference information and a file stored in a lower hierarchy than the folder, the identification stored in the reference information is first determined as to whether or not the file can be accessed. Information is referenced. If the availability information is associated with the folder having the identification information, the process is performed based on “Availability” or “No” stored in the availability information. For example, if “OK” is stored in the permission information associated with the reference destination folder, access to the reference source folder and the files stored in the lower hierarchy is permitted. That is, access to the file related to the access request is permitted. If “No” is stored in the availability information associated with the reference folder, an error is transmitted to the access request source R / W device. Alternatively, a process for making no response may be performed. On the other hand, if the availability information is not associated with the reference destination folder and the reference information is associated, the availability information or the reference information is associated with the folder indicated by the identification information stored in the reference information of the reference destination. It is determined whether or not In this way, it is determined which of the permission information and the reference information is associated with the reference destination folder, and if the reference information is associated with the folder indicated by the identification information stored in the reference information, Further determination is made.

  For example, if the access request from the R / W device (business operator B) 201 is the file 581 shown in FIG. Is determined. At this time, since “area # 1000” is stored in the reference information 532, it is determined whether the availability information or the reference information is associated with the folder 503 to which the identification information of the area # 1000 is assigned. The In this case, since the availability information 541 is associated with the folder 503, it is determined whether “possible” or “no” is stored in the availability information 541. In this case, since “permitted” is stored in the permission information 541, access to the file 581 related to the access request from the R / W device (business operator B) 201 is permitted.

  Further, for example, when the access request from the R / W device (company C) 202 is the file 582 shown in FIG. 5, since the reference information 533 is associated with the folder 505 in the upper hierarchy, the access to the file 582 is performed. Is determined. At this time, since the reference information “area # 2000” is stored in the reference information 533, it is determined which of the availability information and the reference information is associated with the folder 504 having the name of the area # 2000. Since the reference information 532 is associated with the folder 504, which of the availability information and the reference information is associated with the folder 503 assigned the name of the reference information “area # 1000” stored in the reference information 532. Next, it is determined whether or not Since the availability information 541 is associated with the folder 503, it is determined whether “possible” or “no” is stored in the availability information 541. In this case, since “permitted” is stored in the permission information 541, access to the file 582 related to the access request from the R / W device (business operator C) 202 is permitted.

  Next, the availability information output process when a command (inquiry) for obtaining availability information in order to determine whether a file can be accessed from the R / W device will be described. For example, when the mobile communication device 100 receives an inquiry from the R / W device (operator A) 200 as to whether the file 580 can be accessed, it is associated with the folder 503 that is an upper layer of the file 580. The availability information 541 is read out. Then, this availability information 541 is transmitted to the R / W device (operator A) 200.

  Further, for example, when the mobile communication device 100 receives an inquiry from the R / W device (company B) 201 as to whether the file 581 is accessible, the file is associated with the folder 504 that is an upper layer of the file 581. The reference information 532 is read out. Then, this reference information 532 is transmitted to the R / W device (business operator B) 201. The R / W device (company B) 201 that has acquired this reference information 532 outputs an inquiry to the mobile communication device 100 again. Then, the mobile communication device 100 that has received the inquiry again outputs the availability information 541 associated with the folder 503 assigned the name “area # 1000” stored in the reference information 532.

  Further, for example, when the mobile communication device 100 receives an inquiry from the R / W device (operator C) 202 as to whether the file 582 can be accessed, it is associated with the folder 505 that is an upper layer of the file 582. The reference information 533 is read out. Then, this reference information 533 is transmitted to the R / W device (business operator C) 202. The R / W device (company C) 202 that has acquired this reference information 533 outputs an inquiry to the mobile communication device 100 again. The mobile communication device 100 that has received the inquiry again outputs the reference information 532 associated with the folder 504 assigned the name “area # 2000” stored in the reference information 533. The R / W device (company C) 202 that has acquired this reference information 532 outputs an inquiry to the mobile communication device 100 again. Then, the mobile communication device 100 that has received the inquiry again outputs the availability information 541 associated with the folder 503 assigned the name “area # 1000” stored in the reference information 532.

  In this way, the availability information can be acquired by repeating the inquiry until the availability information is transmitted. When the R / W device acquires the availability information, it determines whether or not the data related to the inquiry can be accessed based on the availability information. That is, if “permitted” is stored in the permission information acquired by the R / W device, it is determined that the data related to the inquiry can be accessed. Further, if “No” is stored in the availability information acquired by the R / W device, it is determined that the data related to the inquiry cannot be accessed. When it is determined that the R / W device can access the data related to the inquiry, this data may be accessed by a Read command or a Write command.

  In the example illustrated in FIG. 5, the example in which the reference information or the availability information is associated with the highest hierarchy (that is, the folders 503 to 505) belonging to the provider area has been described. However, reference information or availability information may be associated with a node other than the highest hierarchy in the provider area. For example, reference information or availability information may be associated with lower folders and files belonging to the business operator area. For example, availability information or reference information may be associated with the folder 506 or the file 580 shown in FIG.

  The information “permitted” or “not permitted” stored in the permission information can be rewritten. Specifically, the information stored in the availability information is rewritten based on an instruction from the server device 310.

  As described above, when there is an access request from the R / W devices 200 to 202 to the files 580 to 582 stored in the EEPROM 144, either the permission information or the reference information is associated with the access destination operator area. Is determined. If the availability information is associated with the access-permitted provider area, the availability of access is determined based on “possible” or “not allowed” stored in the availability information. On the other hand, if the reference information is associated with the provider area of the access destination, it is determined whether the permission information or the reference information is associated with the folder indicated by the identification information stored in the reference information. . In this way, while sequentially determining the folders to which the identification information stored in the reference information is assigned, the folder associated with the availability information is identified. And the process based on the permission information linked | related with this specified folder is performed. For example, if “permitted” is stored in the permission information, the access request source R / W devices 200 to 202 are permitted to access the data related to the access request. For example, if “No” is stored in the information stored in the availability information, a process for not permitting access to the R / W devices 200 to 202 that are the access requests is performed. As this processing, for example, processing for notifying an access request source of an error is performed. Further, for example, a process of making no response to the access request source may be performed.

  Further, an inquiry as to whether or not the R / W devices 200 to 202 are accessible may be transmitted to any of the nodes stored in the EEPROM 144. In this case, it is determined whether or not the reference information or availability information is associated with the node related to this inquiry or the node that manages this node. If availability information is associated with the node related to this inquiry, this availability information is transmitted to the R / W devices 200 to 202 that are the inquiry sources. If reference information is associated with the node related to the inquiry, the reference information is transmitted to the R / W devices 200 to 202 that are the inquiry sources. Then, the R / W devices 200 to 202 that have acquired the reference information make an inquiry again. In response to this re-inquiry, the node indicated by the reference information related to this inquiry is referred to, and the reference information or availability information associated with the node is transmitted to the R / W devices 200 to 202 as the inquiry source. In this way, the R / W devices 200 to 202 repeat the inquiry until the availability information is acquired.

[Functional configuration example of non-contact communication system]
FIG. 6 is a block diagram illustrating a functional configuration example of the contactless communication system 400 according to the first embodiment of the present invention. Non-contact communication system 400 includes mobile communication device 100 and R / W devices 200 to 202. In FIG. 6, only the R / W device 200 among the R / W devices 200 to 202 is shown.

  The mobile communication device 100 includes a storage unit 411, a non-contact communication control unit 412, an availability information rewrite unit 413, an information reception unit 414, an information transmission unit 415, and a rewrite instruction reception unit 416 as functional configurations. Prepare.

  The storage unit 411 manages nodes by configuring nodes in a hierarchical structure. Each of the plurality of nodes includes at least one node associated with availability information and one node associated with reference information. The storage unit 411 corresponds to the EEPROM 144 shown in FIG.

  The non-contact communication control unit 412 determines whether the availability information or the reference information is associated with the node that manages the data related to the access request received by the information receiving unit 414. When the availability information is associated with the node that manages the data related to the access request, the non-contact communication control unit 412 refers to the availability information and performs processing based on the content indicated by the availability information. In addition, when the reference information is associated with the node in which the data related to the access request is managed, the non-contact communication control unit 412 refers to the reference information and determines whether the reference information is associated with the node indicated by the reference information. Alternatively, processing based on the content indicated by the reference information is performed. The access request is a signal that is transmitted from the R / W device 200 and requests access to data stored in the storage unit 411. For example, when the availability information is associated with the node that manages the data related to the access request, the non-contact communication control unit 412 stores “Yes” or “No” in the availability information. Judge about. If “permitted” is stored in the permission information, the non-contact communication control unit 412 permits the access request source R / W device 200 to access the data related to the access request. If “No” is stored in the availability information, the non-contact communication control unit 412 performs a process for not permitting access from the information transmission unit 415 to the access request source R / W device 200. For example, processing for notifying an error to the access request source or processing for not responding to the access request source is performed.

  Further, the non-contact communication control unit 412 determines whether or not the availability information or the reference information is associated with the node that manages the data related to the inquiry received by the information reception unit 414. If the availability information is associated with the node that manages the data related to the inquiry, the non-contact communication control unit 412 causes the information transmission unit 415 to transmit the availability information to the R / W device 200 that is the inquiry source. Take control. Further, the non-contact communication control unit 412 transmits the reference information from the information transmission unit 415 to the R / W device 200 as the inquiry source if the reference information is associated with the node in which the data related to the inquiry is managed. To control. When the information receiving unit 423 in the inquiry source R / W device 200 acquires the reference information, the R / W device control unit 421 makes an inquiry to the mobile communication device 100 again. The non-contact communication control unit 412 that has received this inquiry by the information reception unit 414 determines whether the availability information or the reference information is associated with the node indicated by the reference information. In this case, if the availability information is associated with the node indicated by the reference information, the non-contact communication control unit 412 performs control for transmitting the availability information from the information transmission unit 415 to the R / W device 200 as the inquiry source. Do. If the reference information is associated with the node indicated by the reference information, the non-contact communication control unit 412 performs control to cause the R / W device 200 as the inquiry source to transmit the reference information from the information transmission unit 415. In this way, the non-contact communication control unit 412 performs control to transmit the availability information or the reference information every time an inquiry is received from the R / W device 200. The non-contact communication control unit 412 corresponds to the CPU 141 shown in FIG. The non-contact communication control unit 412 is an example of a control unit described in the claims.

  The availability information rewriting unit 413 rewrites the availability information stored in the storage unit 411 based on the rewrite instruction received by the rewrite instruction receiving unit 416. The availability information rewriting unit 413 is an example of a rewriting unit described in the claims.

  The information receiving unit 414 receives an access request or inquiry transmitted by non-contact communication from the information transmitting unit 422 of the R / W device 200. The received access request or inquiry is output to the non-contact communication control unit 412. The information receiving unit 414 is an example of an access request receiving unit described in the claims.

  The information transmission unit 415 transmits each information to the information reception unit 423 of the R / W device 200 based on the control of the non-contact communication control unit 412. For example, the information transmission unit 415 transmits an error to the information reception unit 423 of the R / W device 200 by non-contact communication. The information transmission unit 415 transmits the availability information or the reference information read from the storage unit 411 to the information reception unit 423 of the R / W device 200 by non-contact communication.

  Next, a rewriting process when an instruction to rewrite availability information is issued from the server device 310 will be described. First, the rewrite instruction receiving unit 416 that has received a rewrite instruction indicating an instruction to rewrite availability information from the server device 310 outputs the content of the rewrite instruction to the availability information rewriting unit 413. Then, the availability information rewriting unit 413 rewrites the availability information associated with the node based on the content of the rewrite instruction. This rewrite instruction is, for example, an instruction to rewrite the contents of the permission information associated with a specific node (for example, rewrite from accessible to inaccessible).

  Next, the functional configuration of the R / W device 200 will be described. The R / W device 200 includes an R / W device control unit 421, an information transmission unit 422, and an information reception unit 423 as functional configurations.

  The R / W device control unit 421 causes the information transmission unit 422 to transmit an access request to the data stored in the storage unit 411. In this case, the mobile communication device 100 determines whether access to the data related to the access request is possible. In addition, when the R / W device 200 determines whether or not the data related to the access request can be accessed, the R / W device control unit 421 causes the information transmission unit 422 to transmit an inquiry. In this case, the R / W device control unit 421 receives availability information or reference information received by the information reception unit 423. When the R / W device control unit 421 acquires the availability information, it determines whether or not the data related to the inquiry can be accessed based on the availability information. On the other hand, when the R / W device control unit 421 acquires the reference information, the information transmission unit 422 is caused to transmit another inquiry. The R / W device control unit 421 corresponds to the CPU 210 shown in FIG. The R / W device control unit 421 is an example of a determination unit described in the claims.

  The information transmission unit 422 transmits an access request to the information reception unit 414 of the mobile communication device 100 by non-contact communication based on an instruction from the R / W device control unit 421. Further, the information transmission unit 422 transmits an inquiry to the information reception unit 414 of the mobile communication device 100 by non-contact communication based on an instruction from the R / W device control unit 421.

  The information reception unit 423 receives availability information or reference information from the information transmission unit 415 of the mobile communication device 100 by non-contact communication and transmits it to the R / W device control unit 421. The access request transmission unit 422 and the information reception unit 423 correspond to the non-contact communication unit 213 illustrated in FIG.

[Communication example of mobile communication device]
Next, an example of non-contact communication operation in the non-contact communication system 400 will be described with reference to FIGS. In the description of this operation, it is assumed that reference information and availability information are associated with folders in the EEPROM 144 as shown in FIG. Further, it is assumed that the R / W devices 200 to 202 of each business operator have an appropriate key and can access only the business operator area assigned uniquely. FIG. 7 will be described in detail with reference to FIGS. 8 and 9. 8 and 9 are diagrams schematically showing an operation flow of the contactless communication system 400 according to the first embodiment of the present invention. The person (owner 701) shown in FIGS. 8 and 9 is the owner of the mobile communication device 100. In the description of this operation example, the description of the polling signal performed between the R / W devices 200 to 202 and the mobile communication device 100 and the exchange related to the response reaction is omitted.

  FIG. 7 is a sequence diagram for explaining the operation of contactless communication system 400 according to the first embodiment of the present invention.

  First, when the mobile communication device 100 communicates with the R / W device (operator A) 200, since “permitted” is stored in the availability information 541 of the EEPROM 144, the R / W device (operator A) 200. Is permitted to access data in the operator A area 561. For example, as shown in FIG. 8A, when the owner 701 brings the mobile communication device 100 closer to the R / W device 200 (710), the R / W device (business operator A) 200 reads data from the EEPROM 144. A Read command is transmitted (FIG. 7, 601). At this time, since the R / W device (operator A) 200 can access the data in the operator A area 561, the data in the operator A area 561 is read (FIG. 7, 602).

  8A, when the owner 701 brings the mobile communication device 100 closer to the R / W device 201 (711), the R / W device (business operator B) 201 reads data from the EEPROM 144. A Read command is transmitted (FIG. 7, 603). At this time, since the R / W device (company B) 201 can access the data in the company B area 562, the data in the company B area 562 is read (604 in FIG. 7).

  Further, as shown in FIG. 8A, when the owner 701 brings the mobile communication device 100 closer to the R / W device 202 (712), the R / W device (business operator C) 202 reads data from the EEPROM 144. For this purpose, a Read command is transmitted (605 in FIG. 7). At this time, since the R / W device (company C) 202 can access the data in the company C area 563, the data in the company C area 563 is read (FIG. 7, 606).

  Here, an operation for preventing access to a file stored in the EEPROM 144 of the mobile communication device 100 when the mobile communication device 100 is stolen will be described.

  For example, as illustrated in FIG. 8B, it is assumed that the mobile communication device 100 is stolen from the owner 701 and the acquirer 702 possesses the mobile communication device 100. In that case, as shown in FIG. 9A, the owner 701 notifies the business operator A that the owner 701 has stolen (713).

  The business operator A requests the system administrator 703 managing the server device 310 to change the availability information 541 from “permitted” to “rejected” so that the service in the business operator A area 561 is not used. (FIG. 9 (a), 714). Specifically, an invalidation request is transmitted from the R / W device (operator A) 200 to the server device 310 (FIG. 7, 607). Then, the server device 310 outputs a rewrite instruction indicating an instruction to rewrite the availability information 541 from “OK” to “NO” to the mobile communication device 100 (FIGS. 9A and 715). The mobile communication device 100 receives the rewrite instruction via the mobile communication network 320 (FIGS. 9A and 716). In this way, the mobile communication device 100 receives the rewrite instruction from the server device 310 (FIG. 7, 608). Then, based on the rewrite instruction, the CPU 141 of the non-contact communication unit 140 rewrites the availability information 541 associated with the folder 503 stored in the EEPROM 144 from “Yes” to “No”. As described above, when “No” is stored in the permission information 541, each of the R / W devices 200 to 202 cannot access data for which access is authorized.

  For example, when the acquirer 702 brings the mobile communication device 100 close to the R / W device (operator A) 200 (FIGS. 9B and 717), the R / W device (operator A) 200 receives data from the EEPROM 144. A Read command for reading is transmitted (609 in FIG. 7). At this time, since “No” is stored in the availability information 541, “Error” indicating that access is not possible is output to the R / W device (operator A) 200 (610). Therefore, even if the acquirer 702 brings the mobile communication device 100 close to the R / W device (provider A) 200, the R / W device (provider A) 200 cannot access the data in the provider A area 561. Can not use the service.

  Further, when the acquirer 702 brings the mobile communication device 100 close to the R / W device (business operator B) 201 (FIGS. 9B and 718), the R / W device (business operator B) 201 receives data from the EEPROM 144. A Read command for reading is transmitted (FIG. 7, 611). At this time, since “area # 1000” is stored in the reference information 532, it is determined whether or not the reference information or availability information is associated with the folder 503 to which the identification information of the area # 1000 is assigned. In this case, since “No” is stored in the permission information 541 associated with the folder 503, “Error” indicating that access is not possible is output to the R / W device (operator B) 201 (612). . Therefore, even if the acquirer 702 brings the mobile communication device 100 closer to the R / W device (provider A) 200, the R / W device (provider B) 201 cannot access the data in the provider B area 562. Can not use the service.

  Further, when the acquirer 702 brings the mobile communication device 100 close to the R / W device (business operator C) 202 (FIGS. 9B and 719), the R / W device (business operator C) 202 receives data from the EEPROM 144. A Read command for reading is transmitted (FIG. 7, 613). At this time, since “area # 2000” is stored in the reference information 533, it is determined whether or not the reference information or availability information is associated with the folder 504 to which the identification information of area # 2000 is assigned. Since the reference information 532 is associated with the folder 504 and “area # 1000” is stored in the reference information 532, the reference information or availability information is associated with the folder 503 to which the identification information of the area # 1000 is assigned. It is determined whether or not it has been. Since the availability information 541 is associated with the folder 503, and “No” is stored in the availability information 541, “Error” indicating that access is not possible is output to the R / W device (operator C) 202 ( 614). Therefore, even if the acquirer 702 brings the mobile communication device 100 closer to the R / W device (business operator C) 202, the R / W device (business operator C) 202 cannot access the data in the business operator C area 563. Can not use the service.

  In the examples shown in FIGS. 7 to 9, “Error” is output from the mobile communication device 100 when “No” is stored in the availability information, but nothing is received from the mobile communication device 100. It may not be output. Accordingly, since the R / W devices 200 to 202 cannot obtain a response response from the mobile communication device 100, the data related to the access request cannot be accessed and the service cannot be used.

[Output example of availability / reference information by mobile communication device]
Next, an example of operation in which availability information or reference information is output from the mobile communication device 100 in response to an inquiry from the R / W devices 200 to 202 will be described. In the description of this operation, it is assumed that reference information and availability information are associated with folders in the EEPROM 144 as shown in FIG.

  FIG. 10 is a sequence diagram for explaining the operation of contactless communication system 400 according to the first embodiment of the present invention.

  First, a case where the mobile communication device 100 is brought close to the R / W device (business operator A) 200 and receives an inquiry from the R / W device (business operator A) 200 will be described. The R / W device (operator A) 200 transmits a polling signal (801). When the mobile communication device 100 is brought close to the R / W device (operator A) 200, the mobile communication device 100 receives this polling signal and transmits response information to the R / W device (operator A) 200. (802). Next, for example, an inquiry as to whether or not the file 580 is accessible is transmitted from the R / W device (operator A) 200 (803). Upon receiving this inquiry, the mobile communication device 100 reads the availability information 541 associated with the highest folder 503 in the operator A area 561 from the EEPROM 144, and the availability information 541 is read from the R / W device (the operator). A) Transmit to 200 (804). In this case, since “permitted” is stored in the permission information 541, the R / W device (operator A) 200 determines that the file 580 related to the inquiry is accessible.

  Next, a case where the mobile communication device 100 is brought close to the R / W device (business operator B) 201 and receives an inquiry from the R / W device (business operator B) 201 will be described. The R / W device (operator B) 201 transmits a polling signal (805). When the mobile communication device 100 is brought close to the R / W device (provider B) 201, the mobile communication device 100 receives this polling signal and transmits response information to the R / W device (provider B) 201. (806). Next, for example, an inquiry as to whether or not the file 581 is accessible is transmitted from the R / W device (business operator B) 201 (807). Upon receiving this inquiry, the mobile communication device 100 reads the reference information 532 associated with the highest folder 504 in the business operator B area 562 from the EEPROM 144, and the reference information 532 is read from the R / W device (business operator). B) Transmit to 201 (808). Next, the R / W device (company B) 201 transmits permission / inhibition information or reference information associated with the folder assigned the name “area # 1000” stored in the reference information 532. Thus, the inquiry is transmitted again to the mobile communication device 100 (809). Receiving the inquiry again, the mobile communication device 100 reads from the EEPROM 144 the availability information 541 associated with the folder 503 to which the name “area # 1000” is assigned, and this availability information 541 is read out from the R / W device. (Operator B) It transmits to 201 (810). In this case, since “permitted” is stored in the permission information 541, the R / W device (business B) 201 determines that the file 581 related to the inquiry is accessible. The determination process is similarly performed when an inquiry as to whether the file 582 is accessible from the R / W device (business operator C) 202 is transmitted. That is, the R / W device (business operator C) 202 repeats the inquiry until the availability information 541 is acquired.

[Operation example of non-contact communication device]
Next, an operation of mobile communication device 100 when R / W devices 200 to 202 transmit an access request to access data stored in EEPROM 144 of mobile communication device 100 will be described.

  FIG. 11 is a flowchart illustrating a processing procedure of access control processing according to the first embodiment of this invention.

  When any of the R / W devices 200 to 202 is brought close to a distance at which the mobile communication device 100 can communicate with each other, it is determined whether there is an access request from the R / W device brought close to the communicable distance. (Step S901). Note that step S901 is an example of an access request reception procedure described in the claims. If there is an access request (step S901; Yes), the non-contact communication control unit 412 determines whether availability information or reference information is associated with a node that manages data related to the access request (step S902).

  If the availability information is associated with the node that manages the data related to the access request (step S902; availability information), the non-contact communication control unit 412 determines whether “possible” is stored in the availability information. (Step S903).

  If “permitted” is stored in the permission information (step S903; Yes), the non-contact communication control unit 412 permits access to the data related to the access request (step S904). On the other hand, if “No” is stored in the availability information (step S903; No), the non-contact communication control unit 412 outputs “Error” to the R / W devices 200 to 202 that are the access requests (step S903). S905). Then, after the operation of step S904 or step S905, the access control process is terminated.

  On the other hand, if the reference information is associated with the node that manages the data related to the access request (step S902; reference information), the non-contact communication control unit 412 refers to the node indicated by the reference information (step S906). Then, the non-contact communication control unit 412 determines whether other reference information is associated with the node indicated by the reference information (step S907). If the availability information is associated with the node indicated by the reference information (step S907; No), the process proceeds to step S903. If other reference information is associated with the node indicated by this reference information (step S907; Yes), steps S906 and S907 are repeated until the node associated with the availability information is identified. Note that steps S902 to S907 are an example of a control procedure described in the claims.

  Next, operations of the mobile communication device 100 when the R / W devices 200 to 202 receive an inquiry as to whether or not the file stored in the EEPROM 144 of the mobile communication device 100 can be accessed are shown in FIG. Will be described.

  FIG. 12 is a flowchart illustrating a processing procedure of availability information output processing according to the first embodiment of this invention. In this example, the illustration and description of the polling signal and the exchange related to the response reaction performed between the R / W devices 200 to 202 and the mobile communication device 100 are omitted.

  When any of the R / W devices 200 to 202 is brought close to a distance at which the mobile communication device 100 can communicate with each other, whether or not there is an inquiry from the R / W device brought close to the communicable distance. Determination is made (step S911). If there is an inquiry (step S911; Yes), the non-contact communication control unit 412 determines which of the availability information and the reference information is associated with the node that manages the data related to the inquiry (step S912).

  If availability information is associated with the node that manages the data related to the inquiry (step S912; availability information), the non-contact communication control unit 412 outputs the availability information to the R / W devices 200 to 202 that are the inquiry sources. (Step S913). Then, the availability information output process ends. On the other hand, if the reference information is associated with the node that manages the data related to the inquiry (step S912; reference information), the non-contact communication control unit 412 sends the reference information to the R / W devices 200 to 202 that are the inquiry sources. Output (step S914).

  Next, the non-contact communication control unit 412 determines whether or not there is an inquiry from the R / W devices 200 to 202 in response to the output of the reference information (step S915). If there is no inquiry (step S915; No), the availability information output process is terminated. On the other hand, if there is an inquiry (step S915; Yes), the process returns to step S912, and steps S912 and S914 are repeated until the availability information is transmitted to the inquiring R / W devices 200 to 202.

  As described above, according to the first embodiment of this invention, by storing the availability information in association with a node, it is possible to easily change the availability of access to information managed by the node. . In addition, by storing the reference information in association with a node other than the node with which the availability information is associated, the information managed by the node is determined based on the availability information associated with the node indicated by the reference information. It is possible to easily change whether or not access is possible. Further, if reference information is associated with a plurality of nodes, whether or not access is possible is determined based on node availability information specified by sequentially tracing the nodes indicated by the reference information. Thus, for example, when the availability information of a certain business operator area is rewritten, all of the plurality of business operator areas that are determined to be accessible by referring to this availability information follow the renewed availability information. Therefore, since it is possible to change the accessibility of these plurality of business operator areas with only one rewrite, the more business operator areas that follow the availability information specified by the reference information, the more beneficial.

<2. Second Embodiment>
[Configuration example of non-contact communication system]
FIG. 13 is a diagram illustrating a system configuration example of the contactless communication system 401 according to the second embodiment of the present invention. The non-contact communication system 401 includes an IC card 800, an R / W device (provider A) 200, an R / W device (provider B) 201, an R / W device (provider C) 202, and a server device. 310. The second embodiment of the present invention is different from the first embodiment of the present invention in that an IC card 800 is used instead of the mobile communication device 100. This is substantially the same as in the first embodiment. For this reason, in the following, parts common to the first embodiment of the present invention will be denoted by the same reference numerals, and description thereof will be omitted, which is different from the example shown in the first embodiment of the present invention. The explanation will focus on the part.

  The internal configuration of the IC card 800 is substantially the same as the internal configuration of the non-contact communication 140 shown in FIG. 3 except that the bus of the IC card 800 is not connected to an external bus. In the following, portions common to the non-contact communication unit 140 are denoted by the same reference numerals, description thereof is omitted, and portions different from the non-contact communication unit 140 are mainly described. The IC card 800 is assumed to store identification information for identifying each IC card in the EEPROM 144.

  The R / W devices 200 to 202 are substantially the same as the internal configuration shown in FIG. 4, but are different in that different availability information rewrite lists are stored in the storage unit 212. The permission information rewrite list is a list in which identification information of the IC card is recorded, and the permission information of the IC card in which the identification information is recorded in this list is rewritten.

[Operation example of non-contact communication system]
Next, the operation of the contactless communication system 401 when the owner of the IC card 800 stops using the IC card 800 will be described. In the following description of the operation, the data stored in the EEPROM 144 is described as being the same as the data structure shown in FIG.

  FIG. 14 is a sequence diagram for explaining the operation of contactless communication system 401 in the second embodiment of the present invention. In this example, a case will be described as an example in which the mobile communication device 100 determines whether or not access to data related to an access request is possible. However, the present invention can be similarly applied to a case where the R / W device side determines whether or not data relating to the access request can be accessed. First, as in the case of the first embodiment, when the IC card 800 is brought close to the R / W device (operator A) 200, a Read command is transmitted (601) and Data is output (602). . Similarly, the IC card 800 can normally communicate with the R / W device (company B) 201 and the R / W device (company C) 202.

  Next, the operation of the non-contact communication system 401 when the owner of the IC card 800 stops using the IC card 800 will be described.

  The owner of the IC card 800 contacts the business operator A and offers to stop using the service. Upon receiving this offer, the business operator A adds the identification information of the IC card 800 to the availability information rewrite list, and stores the new availability information rewrite list in the storage unit 212.

  At this time, it is assumed that the owner of the IC card 800 brings the IC card 800 close to the R / W device (the business operator A) 200 in order to receive the service provided by the business operator A using the IC card. The R / W device (operator A) 200 is transmitting a polling signal (620), and the IC card 800 that has received the signal transmits response information (621). The R / W device (operator A) 200 that has received the response information including the identification information of the IC card 800 includes whether or not the identification information of the IC card 800 is included in the availability information rewrite list stored in the storage unit 212. Determine whether. In the case of this example, since the identification information of the IC card 800 is included in the availability information rewrite list, the R / W device (operator A) 200 stops using the service by the IC card 800. Specifically, the R / W device (operator A) 200 outputs a rewrite instruction indicating an instruction to rewrite the availability information 541 associated with the folder 503 to “No” to the IC card 800 (622). The R / W device (operator A) 200 that has received the rewrite instruction rewrites the availability information 541 associated with the folder 503 to “No”. Then, the IC card 800 transmits a normal response indicating that the rewriting has been normally completed to the R / W device (operator A) 200 (623). This rewriting is performed by the non-contact communication control unit 412.

  In this way, by rewriting the availability information of the business operator A area 561 to “no”, even if the R / W device (business company A) 200 accesses the file 580 of the business operator A area 561, the availability information 541 is not changed. Cannot access because it is “No”. Similarly, even if an attempt is made to access the file 581 or 582 of the business operator B area 562 and the business operator C area 563, each file 581 or 582 is referred to by referring to “No” stored in the availability information 541. Is not accessed.

  For example, when the acquirer of the IC card 800 holds the IC card 800 over the R / W device (operator A) 200, the R / W device (operator A) 200 reads data in the operator A area 561. A Read command is transmitted (609). Upon receiving this, the IC card 800 determines whether “OK” or “NO” is stored in the permission information 541 associated with the folder 503 that manages the data requested to be accessed. In this case, since “No” is stored in the availability information 541, the IC card 800 outputs “Error” to the R / W device (operator A) 200 (610). Similarly, when the acquirer of the IC card 800 holds the IC card 800 over the R / W device (company B) 201, the R / W device (company B) 201 reads data in the company B area 562. The Read command is transmitted (611). The IC card 800 that has received this refers to the folder 503 based on the folder identification information stored in the reference information 532 associated with the folder 504 that manages the access requested data. Then, the IC card 800 determines whether “OK” or “NO” is stored in the permission information 541 associated with the folder 503. In this case, since “No” is stored in the availability information 541, the IC card 800 outputs “Error” to the R / W device (business operator B) 201 (612). Similarly, when the acquirer of the IC card 800 holds the IC card 800 over the R / W device (business operator C) 202, the R / W device (business operator C) 202 reads the data in the business operator C area 563. The Read command is transmitted (613). The IC card 800 that has received this refers to the folder 504 based on the folder identification information stored in the reference information 533 associated with the folder 505 that manages the access requested data. Next, the IC card 800 determines whether “OK” or “NO” is stored in the permission information 541 associated with the folder 503 indicated by the reference information 532 associated with the folder 504. In this case, since “No” is stored in the availability information 541, the IC card 800 outputs “Error” to the R / W device (operator C) 202 (614).

  As described above, according to the second embodiment of the present invention, the availability information and the reference information can be used also for a non-contact communication device such as an IC card that does not have a communication function with a mobile communication network. . Accordingly, it is an object of the present invention to easily perform a procedure for stopping or starting services of a plurality of business operators even in a non-contact communication device such as an IC card.

<3. Third Embodiment>
[Data structure of EEPROM]
FIG. 15 is a diagram illustrating a data structure example of the EEPROM 144 according to the third embodiment of the present invention. The data structure of the EEPROM 144 according to the third embodiment of the present invention is that the date / time information 571 is stored in the availability information 541 associated with the folder 503 shown in FIG. Different from form. In addition, each of the R / W devices 200 to 202 includes a timer unit in the CPU 210, and acquires current date and time information from the timer unit. Other parts are substantially the same as those of the first embodiment of the present invention. For this reason, in the following, parts common to the first embodiment of the present invention will be denoted by the same reference numerals, and description thereof will be omitted, which is different from the example shown in the first embodiment of the present invention. The explanation will focus on the part.

  The date / time information 571 is information specifying whether or not data managed by a node (folder or file) belonging to the folder 503 can be accessed by an expiration date. For example, a case where there is an access request from the R / W device 200 in the contactless communication system 400 shown in FIG. 1 will be described.

  When there is an access request from the R / W device 200 to the file 580, it is determined whether the availability information or the reference information is associated with the node. In this case, since the availability information 541 is associated with the folder 503 that is a higher node, the availability of access to the file 580 is determined based on the availability information 541.

  Here, the date / time information 571 “2009/01/01; 12:00” (January 1, 2009, 12:00) is stored in the availability information 541, and this date / time information 571 is stored in the R / W device 200. Sent. The CPU 210 of the R / W device 200 that has acquired the date / time information 571 by non-contact communication acquires the current time from the time measuring unit, and compares this with the date / time information 571 to determine whether access is possible. That is, if the date / time information 571 is a date before the current time, it is determined that access is possible, and if the date / time information 571 is a date / time before the current time, it is determined that access is not allowed.

  For example, if the current time is “2008/12/01; 12:00” (December 1, 2008, 12:00), it is compared with the date / time information 571 and the date / time information 571 is earlier than the current time. Therefore, it is determined that access is possible. Therefore, the R / W device 200 can access the file 580. Note that if the date information 571 is a date earlier than the current time, it is determined that access is not possible, and if the date information 571 is a date earlier than the current time, it may be determined that access is possible. In this example, a case will be described as an example in which the mobile communication device 100 determines whether or not access to data related to an access request is possible. However, the present invention can be similarly applied to a case where the R / W device side determines whether or not data relating to the access request can be accessed.

  Thus, according to the third embodiment of the present invention, whether or not access is possible is determined by comparing the date and time information stored in the availability information with the current time. As a result, it is possible to easily change whether or not access to the information managed by the node associated with the date and time information is based on the date and time information.

  As described above, according to each embodiment of the present invention, it is possible to easily perform a procedure for stopping or starting the services of the operators A to C.

  In the embodiment of the present invention, the mobile communication device 100 or the IC card 800 has been described as an example of the non-contact communication device. However, for example, the non-contact communication device such as an electronic device having an IC card function is used. Each embodiment of the present invention can be applied.

  The embodiment of the present invention is an example for embodying the present invention, and has a corresponding relationship with the invention-specific matters in the claims as described above. However, the present invention is not limited to the embodiments, and various modifications can be made without departing from the scope of the present invention.

  The processing procedure described in the embodiment of the present invention may be regarded as a method having a series of these procedures, and a program for causing a computer to execute the series of procedures or a recording medium storing the program May be taken as As this recording medium, for example, a CD (Compact Disc), an MD (MiniDisc), a DVD (Digital Versatile Disk), a memory card, a Blu-ray Disc (registered trademark), or the like can be used.
