Description

  The present invention relates to an information processing apparatus, method, and program, and more particularly, to an information processing apparatus, method, and program that enable easy registration or cancellation of a service used in processing of an IC chip.

  In recent years, cellular phones and the like in which a non-contact IC chip such as FeliCa (registered trademark) is incorporated have become widespread. For example, a user can simply hold an electronic money by holding the cellular phone over a terminal (reader / writer) installed in a store. You can easily make payments with.

  By the way, such processing (for example, payment processing) is realized by appropriately accessing a predetermined memory area in the IC chip and performing reading and writing on the data stored therein.

  In the following, a memory area accessed in processing (a memory area in which data to be accessed is stored) is referred to as a service memory area, and a processing operation for accessing the service memory area is referred to as a service.

  In order to execute a predetermined process, it is necessary to register a service according to the process. However, when there are a plurality of services, the services can be registered hierarchically as shown in FIG. Reference 1). In this example, a directory “area” is provided, subordinate to “area A1”, “area A2” is provided, and service S1-1 is registered, and subordinate to “area A2”, service S2-1 is provided. And service S2-2 are registered respectively.

  By registering services in “areas” in this way (by registering them hierarchically), it is possible to easily manage services executed in a series of transactions.

  Here, the service registration process will be described with reference to the flowchart of FIG.

  In step S1, one of the service to be registered and “area” (for example, “area” and service shown in FIG. 1) is selected. In the following, when it is not necessary to distinguish between a service and an “area”, they are simply referred to as a service.

  In step S2, a physical address & on a predetermined memory area (hereinafter referred to as data area) 1A of the nonvolatile memory in the IC chip in the service memory area corresponding to the service selected in step S1 is acquired.

  For example, as shown in FIG. 3, the physical address & 01 of the service memory area of the service S2-1 is secured.

  The services are registered in the order according to the hierarchical structure to be formed. In the example of FIG. 3, “Area A1” and “Area A2” higher than the service S2-1 are already registered, and the service S2- 1 shows the state of the memory area in the IC chip when it is registered from now.

  In step S3, the service code for identifying the service is associated with the logical address # in the order corresponding to the hierarchical structure as shown in FIG. 3, and is set in the logical file 2 in a predetermined memory area in the IC chip. .

  In this example, a logical address # is associated with the service code of each service in the order of the hierarchical structure from the top logical address #. That is, the first logical address # 00 is associated with the service code of the highest “area A1”, and the second logical address is assigned to the service code of “area A2” subordinate to “area A1”. # 01 is associated, and the third logical address # 02 is associated with the service code of the service S2-1 subordinate to “area A2”.

  Next, in step S4, the physical address & acquired in step S2 is transferred to a predetermined memory area (hereinafter referred to as temporary registration area) 3 of the volatile memory in the IC chip as shown in FIG. It is stored (temporarily registered) in the storage unit 21 at a position corresponding to the order of the logical address # associated with the code.

  In the example of FIG. 3, the physical address & 00 of “Area A1” associated with the first logical address # 00 is stored in the first storage unit 21 of the temporary registration area 3, and the second logical address # 00 is stored. The physical address & 04 of “area A2” associated with the address # 01 is stored in the second storage unit 21 of the temporary registration area 3, and the service associated with the third logical address # 02. The physical address & 01 of S2-1 is stored in the third storage unit 21 of the temporary registration area 3.

  In step S5, the physical address & (temporarily registered service physical address &) stored in the temporary registration area 3 in step S4 is a predetermined memory area (hereinafter referred to as a management area) of the nonvolatile memory in the IC chip. ) 1B is stored in the storage unit 11 at a position corresponding to the order of the logical address # associated with the service code. That is, as shown in FIG. 4, the physical address & stored in the temporary registration area 3 is copied to the storage unit 11 at the corresponding position in the management area 1B.

  In the example of FIG. 4, the physical address & 00 of “area A1” stored in the first storage unit 21 of the temporary registration area 3 is stored in the first storage unit 11 of the management area 1B and temporarily registered. The physical address & 04 of “area A2” stored in the second storage unit 21 of the area 3 is stored in the second storage unit 11 of the management area 1B, and the third address of the temporary registration area 3 The physical address & 01 of the service S2-1 stored in the storage unit 21 is stored (copied) in the third storage unit 11 of the management area 1B.

  In step S6, as shown in FIG. 4, the physical address & (service memory area) on the data area 1A stored in the management area 1B in step S5 is accessed in the service, necessary definition information, etc. Is stored (mainly registered).

  In the example of FIG. 4, data accessed in the service S2-1, necessary definition information, and the like are stored in the physical address & 01.

  In step S7, it is determined whether or not all services to be registered have been registered. If it is determined that there are remaining unregistered services, the process returns to step S1, the next service is selected, and the steps after step S2 are selected. Processing is performed in the same way.

  If it is determined in step S7 that all services to be registered have been registered, the process ends.

  That is, when services are registered in the hierarchical structure shown in FIG. 1, “area A1”, “area A2”, “service S2-1”, “service S2-2”, and “service” in the order of FIGS. 5A to 5E. Each of “S1-1” is provisionally registered and fully registered.

  Next, the process for canceling the registration of the service performed as described above will be described with reference to the flowchart of FIG.

  In step S11, the entire physical address & (physical address & of the service memory area of the registered service) stored in the management area 1B is copied to the temporary registration area 3. Note that all data stored in the temporary registration area 3 at the time of service registration is deleted after the registration process.

  In step S12, one service is selected, and in step S13, the logical address # corresponding to the service code is detected from the logical file 2 and deleted.

  In step S14, the physical address & is deleted (temporarily released) from the storage unit 21 at the position corresponding to the detected logical address # in the temporary registration area 3.

  Next, in step S15, the physical address & is deleted from the storage unit 11 corresponding to the storage unit 21 of the temporary registration area 3 in which the physical address & has been deleted in step S14 in the management area 1B.

  In step S16, the data stored in the physical address & deleted from the management area 1B in step S15 in the data area 1A is deleted (this release is performed).

  In step S17, it is determined whether or not the registration of all services has been cancelled. If it is determined that there is still a service that has not been cancelled, the process returns to step S11, and the next service is selected. These processes are performed in the same manner.

JP 2004-310557 A

  However, in the method described above, provisional registration and main registration are performed for each service, and the service is registered. For example, when the power of the device incorporating the IC chip is turned off and the registration process is terminated halfway, The registered service will remain registered as it is.

  For example, as illustrated in FIG. 5C, when the service registration process is completed after the service S2-1 is registered, some services are registered and remain in the state illustrated in FIG. 5C.

  When re-registration is performed from such a state, it is necessary to confirm the registration status of the current service and perform re-registration based on the confirmation result.

  In the above-described method, the provisional cancellation and the main cancellation are performed for each service, and the registration of the service is canceled. Therefore, when the cancellation process is finished halfway, some services that were not canceled are registered as they are. It will remain.

  When re-cancellation is performed from such a state, it is necessary to confirm the registration status of the current service and perform re-cancellation based on the confirmation result.

  In other words, conventionally, if the service registration process or deregistration process is terminated halfway, when resuming registration or deregistration, it is necessary to grasp the current registration status and determine the re-registration and re-cancellation method based on the results.

The registration unit temporarily registers all access operations to be registered, and After all the provisional registration, the provisionally registered access operation is fully registered.

  When registering the access operation by forming a hierarchical structure, the registration unit can register the access operation for each directory forming the hierarchical structure.

  The registration unit further includes a cancellation unit that cancels the registration of the access operation registered by the registration unit, and the cancellation unit temporarily cancels the registration of all the access operations to be canceled and temporarily cancels the registration of all the access operations. It is possible to cancel the registration of the released access operation.

  The information processing method of the present invention includes a registration step of registering an access operation to a service memory area in which data to be accessed is stored, and the registration step temporarily registers all access operations to be registered. After all the provisional registration, the provisionally registered access operation is fully registered.

  The program of the present invention includes a registration step of registering an access operation to a service memory area in which data to be accessed is stored. The registration step temporarily registers all access operations to be registered, and all access operations are performed. After the temporary registration, the temporarily registered access operation is fully registered.

  In the information processing apparatus, method, and program of the present invention, an access operation to the service memory area in which the access target data is stored is registered, and all access operations to be registered are temporarily registered, and the access operation is performed. After all of these are temporarily registered, the temporarily registered access operation is fully registered.

  According to the present invention, service registration or deregistration in an IC chip can be performed quickly.

  FIG. 7 shows a configuration example of the IC chip 11 to which the present invention is applied. The IC chip 11 is used by being incorporated in, for example, an IC card (not shown) or a mobile phone.

  The RF unit 22 performs wireless communication with a reader / writer (not shown) via an antenna (not shown).

  The memory 23 includes a nonvolatile memory 31 and a volatile memory 32. The nonvolatile memory 31 includes a data area 41A in which a service memory area in which data to be accessed is stored, a service memory A management area 41B in which the physical address & of the area is stored, and a logical file 42 in which the service code assigned to the access operation (service) to the service memory area is associated with the logical address #. The volatile memory 32 is provided with a temporary registration area 43 in which a physical address & is temporarily registered when a service is registered.

  The authentication unit 24 performs authentication of a service whose execution is restricted based on a password assigned to the service.

  The control unit 21 controls each unit.

  Next, the service registration process will be described with reference to the flowchart of FIG. Here, as shown in FIG. 1, each service and “area” are registered.

  In step S <b> 21, the control unit 21 selects one of the service to be registered and “area” (for example, “area” and service to be registered as illustrated in FIG. 1). In the following, when it is not necessary to distinguish between a service and an “area”, they are simply referred to as a service.

  In step S22, the control unit 21 acquires the physical address & on the data area 41A of the service memory area in which the data of the service selected in step S21 is stored.

  In step S23, the control unit 21 associates the logical address # with the service code for identifying the service in the order corresponding to the hierarchical structure, and sets the service code in the logical file 42.

  In this example, a logical address # is associated with the service code of each service in the order of the hierarchical structure from the top logical address #.

  Next, in step S24, the control unit 21 stores the physical address & acquired in step S22 in the storage unit 61 at the position corresponding to the order of the logical address # associated with the service code in the temporary registration area 43. Store (temporarily register).

  In step S25, the control unit 21 determines whether or not all the services to be registered have been temporarily registered. If it is determined that there are remaining services that have not been temporarily registered, the control unit 21 returns to step S21 and performs the subsequent processing. Do the same.

  If it is determined in step S25 that all services to be registered have been provisionally registered, that is, for example, as shown in FIG. 9, the physical address & of the service memory area of each registered service (including “area”) Is acquired (step S22), the service code is set in the logical file 42 (step S23), and the physical address & is temporarily registered in the temporary registration area 43 (step S24), the process proceeds to step S26.

  In step S26, the control unit 21 stores (copies) the physical address & stored in the temporary registration area 43 in the corresponding storage unit 51 of the management area 41B as shown in FIG.

  Next, in step S27, as shown in FIG. 10, the control unit 21 moves the data area 41A into the area indicated by the physical address & stored in the storage unit 51 of the management area 41B in step S26 in each service. Stores data to be accessed (registration is performed).

  Thereafter, the process ends. As described above, after all the services to be registered are provisionally registered (step S24), the main registration is performed collectively (step S27). For example, the power of the device incorporating the IC chip 11 is turned off. Even if the service registration process ends in the middle, since no services are registered during temporary registration (FIG. 9), some services registered before the end are registered as is, as in the past. It can be prevented from remaining. Therefore, when re-registration is performed, it is not necessary to confirm the registration status of the service, it is only necessary to start the registration again, and the re-registration process can be performed quickly.

  Next, processing for canceling registration of a service will be described with reference to the flowchart of FIG.

  In step S31, the control unit 21 stores all the physical addresses & (physical address & of the service memory area of the registered service) stored in the management area 41B in the corresponding storage unit 61 of the temporary registration area 43. make a copy. The data stored in the temporary registration area 43 at the time of service registration has been deleted.

  In step S32, the control unit 21 selects one area to be deregistered. In step S33, the control unit 21 detects the logical address # corresponding to the area and the service code of the service subordinate to the area from the logical file 42, and collectively. And delete it.

  In step S34, the control unit 21 collectively deletes the physical address & stored in the storage unit 61 at the position corresponding to the logical address # detected in step S33 in the temporary registration area 43 (temporarily canceling). ).

  In step S35, the control unit 21 deletes the data stored in the physical address & deleted from the management area 41B in the data area 41A in step S34 (cancel this).

  Thereafter, the process ends. As described above, after temporarily canceling all areas and services subordinate to that area at once, this release was made so that even if the release process ends in the middle, Since none of the registrations is canceled, it is possible to prevent a part of services that have not been canceled from being registered as they are as in the conventional case. As a result, in the re-deletion, it is not necessary to confirm the current registration status, and it is only necessary to start the deregistration process from the beginning, so that the re-cancellation process can be easily performed.

  In the present specification, the steps described in the flowcharts are executed in parallel or individually even if they are not necessarily processed in time series, as well as processes performed in time series in the described order. It also includes processing.
