  FIG. 1 is a block diagram showing functions of the mobile device 100 and the backup server 200 in the backup system of the present embodiment. The mobile device 100 causes the backup server 200 to store data such as telephone directory data and schedule data, and also stores coupon data having electronic value and usage restrictions, thereby backing up the data. be able to.

  The mobile device 100 includes a data transmission / reception unit 101, a data synchronization UI (User Interface) unit 102, a data synchronization protocol processing unit 103 (synchronization unit), a data update history management unit 104 (history management unit), and a data storage unit 105 (memory). Means), a browsing / utilizing unit 106 (coupon data utilizing unit), and a DRM (Digital Rights Management) processing unit 107. This mobile device 100 is realized by the hardware configuration shown in FIG.

  FIG. 2 is a block diagram showing a hardware configuration of mobile device 100. As shown in FIG. 2, the mobile device 100 shown in FIG. 1 physically includes a CPU 11, a RAM 12 and a ROM 13 that are main storage devices, an input device 14 such as a keyboard and a mouse that are input devices, and an output such as a display. The computer 15 includes a device 15, a communication module 16 that is a data transmission / reception device such as a network card, an auxiliary storage device 17 such as a hard disk, a non-contact type IC card 18, and the like. Each function described in FIG. 1 has an input device 14, an output device 15, and a communication module 16 under the control of the CPU 11 by reading predetermined computer software on hardware such as the CPU 11 and the RAM 12 shown in FIG. 2. This is realized by operating the (wireless communication unit) and reading and writing data in the RAM 12 and the auxiliary storage device 17. In the present embodiment, the non-contact type IC card 18 is used when acquiring or using coupon data, which will be described later, and the user installs the non-contact type IC card 18 in a store or the like. The mobile device 100 can acquire and use coupon data by performing an operation of holding the reader / writer. Hereinafter, each functional block will be described based on the functional blocks shown in FIG.

  The data transmission / reception unit 101 is a part that communicates with the backup server 200, and is a part that performs transmission / reception of data according to a synchronization process by the data synchronization protocol processing unit 103 or the like.

  The data synchronization UI unit 102 is a part that accepts user operations such as synchronization processing operations.

  The data synchronization protocol processing unit 103 operates the data synchronization UI unit 102, and when there is a synchronization request from the backup server 200, or other predetermined processing (for example, coupon data acquisition processing or update processing). Is a part that performs protocol processing for synchronizing user data. For example, protocol processing based on the datasync standard standardized by OMA (Open Mobile Alliance) is performed. The data transmission / reception unit 101 performs transmission / reception of difference data among user data based on processing by the data synchronization protocol processing unit 103, and performs synchronization processing of user data. The synchronization processing here is processing for taking consistency so that the user data stored in the backup server 200 and the mobile device 100 are the same, and there is a difference in the user data The difference data is transmitted to the mobile device 100 or the backup server 200.

  For example, when the schedule data stored in the mobile device 100 is changed, the difference data including the changed portion is transmitted to and stored in the backup server 200 to ensure data consistency. In addition, the actual number of times of use of coupon data stored in the mobile device 100 (hereinafter referred to as the number of times of use) is compared with the number of times of use of coupon data whose data ID stored in the backup server 200 matches, When they are different (that is, when they are small), a process of rewriting the coupon data and the number of times of use is performed. For example, the data synchronization protocol processing unit 103 sends data “coupon data xx (use count / total use count): REPLACE”, and the backup server 200 performs a process of rewriting the backup data for the coupon data. In addition, the data synchronization protocol processing unit 103 can notify the addition or deletion. If the data synchronization protocol processing unit 103 notifies the backup server 200 of the coupon data name (or data ID) and the instruction content, the notification format is not limited to the above.

  Further, when the data stored in the backup server 200 is changed, for example, when the coupon data is changed to new coupon content, new coupon data is transmitted to the mobile device 100, and a new Rewritten with coupon data.

  Further, the data synchronization protocol processing unit 103 is a part that transmits / receives difference data, performs update processing, and performs management control of the data update history management unit 104. For example, when synchronization processing is performed, data update A clear process for erasing the update history information stored in the history management unit 104 is performed.

  The data update history management unit 104 is a part that manages the update history of user data stored in the data storage unit 105 when coupon data is used by the browsing / use unit 106. For example, FIG. As shown, the update history information is recorded. FIG. 3 is an explanatory diagram showing update history information stored in the data update history management unit 104.

  As shown in FIG. 3, in the update history information, a data ID indicating coupon data, data, and Sync information are described in association with each other. Sync information is information indicating whether user data has been deleted, added, or updated. In FIG. 3, for example, it is shown that data ID “00000007018”, coupon data C, and DELETE are associated with each other, and coupon data C indicated by this data ID has been deleted by a user operation, or It is shown that the coupon data has been used up (the number of uses has reached the total available number of times). In addition, REPLACE indicates update and ADD indicates addition.

  The data storage unit 105 is a part that stores user data, and is a part that stores schedule data, telephone book data, photo data, and the like in addition to coupon data. The coupon data is obtained by downloading from an external network, or using non-contact communication or infrared communication. In addition, although there is coupon data that has a limit on the number of times it can be used among some coupon data, when storing such coupon data that has a limit on the number of times that it can be used, the data storage unit 105 displays the coupon data , The number of uses, and the total number of available times are stored in association with each other. Coupon data with a limit on the number of times it can be used is operated by the user holding the reader / writer installed in the store, and 1 is added to the number of times used in association with that operation. The number of possible times will be managed.

  FIG. 4 shows a coupon data management DB (Data Base) stored in the data storage unit 105. As shown in FIG. 4, the data ID in the mobile device 100, data, usage status, data acquisition date, and storage folder are stored in association with each other. In the figure, what is described as "no restriction (NULL)" in the usage status column indicates that there is no usage restriction. In addition, what is described as 0/1 in the usage status column indicates that the usage count is 0 and the total usage count is 1. The save destination folder indicates a folder in which each coupon data is stored, and the coupon data is stored separately for each genre. In addition, when it is used up for the total usable number of times, it is automatically stored in the used folder.

  The browsing / use unit 106 is a part for using coupon data, phone book data, and schedule data stored in the data storage unit 105, and includes, for example, an operation unit, a display, and a non-contact type IC card. . For example, when a user intends to use coupon data, an application for using the coupon data is activated, and the application reads the coupon data. In a state where the application is activated, the user performs an operation of holding the mobile device 100 (non-contact type IC card 18 portion) over a reader / writer installed in the store using the non-contact type IC card 18. As a result, the mobile device 100 receives a predetermined service (acquires predetermined content data) in exchange for adding 1 to the number of times coupon data is used in the DRM processing unit 107 (or subtracting 1 from the remaining number of usable times). , A discounted fee is applied at the time of product purchase), and the user can use coupon data. When using phone book data or the like, the phone book data can be read from the data storage unit 105 by a user operation, and the data can be displayed on the display.

  The DRM processing unit 107 is a part that performs a confirmation process of the number of times of use of coupon data having a limited number of times of use in the coupon data stored in the data storage unit 105. When the DRM processing unit 107 receives an instruction to use one data from the browsing / use unit 106, the DRM processing unit 107 refers to the data storage unit 105 and determines whether the one data is coupon data with a limited number of uses. To check. And when it is confirmed that it is coupon data with the use frequency limitation, the remaining use frequency is confirmed based on the relationship between the use frequency and the total use frequency. When it is confirmed that the coupon data can be used and the coupon data is used in the browsing / use unit 106, a process of adding 1 to the number of uses stored in the data storage unit 105 is performed. When the DRM processing unit 107 determines that the coupon data usage count has reached the total available count, that is, the coupon data has been used up and exceeded the usage limit, the coupon data is stored in the used folder (in the data storage unit 105). To be moved). Further, the fact that the coupon data has been deleted (Sync information is DELETE) is recorded in the data update history management unit 104.

  With such a configuration, the mobile device 100 can be treated as deleted when coupon data with a limited number of uses is used up, and further, the use state can be synchronized with the backup server 200. Inconsistency between the usage state stored in the mobile device 100 and the usage state stored in the backup server 200 can be prevented. Next, the configuration of the backup server 200 will be described.

  The backup server 200 includes a data transmission / reception unit 201, a data synchronization protocol processing unit 202 (update means), and a data storage unit 203 (storage means). Similar to the hardware configuration shown in FIG. 2, the backup server 200 also includes a CPU, a RAM, a ROM, and the like, and is realized by operating according to a program stored in advance. Hereinafter, each component will be described.

  The data transmission / reception unit 201 is a part that transmits / receives user data such as coupon data to / from the mobile device 100.

  The data synchronization protocol processing unit 202 is a part that performs synchronization processing for ensuring the consistency of user data with the mobile device 100 in accordance with the DataSync standard, and is added to or deleted from user data stored in the backup server 200. When correction or the like occurs, the mobile device 100 operates to transmit difference data. In addition, when the data synchronization protocol processing unit 202 receives a notification of deletion (update, addition) of coupon data xx such as “coupon data xx: DELETE (REPLACE, ADD)” from the mobile device 100, the data synchronization protocol processing unit 202 stores data in the data storage unit 203. The stored coupon data xx is deleted (updated or added). Similarly to the above, coupon data to be processed can be specified by a coupon data name or a data ID.

  The data storage unit 203 is a part that stores user data that has received a backup request from the mobile device 100 via the data synchronization protocol processing unit 202. The backup server 200 (data synchronization protocol processing unit 202) stores user data in the data storage unit 203 in response to a request from the mobile device 100, reads out the data from the data storage unit 203, and transmits it to the mobile device 100. Can do. In this embodiment, the data storage part 203 can memorize | store coupon data, its use frequency, and total use frequency.

  By configuring the backup server 200 in this way, coupon data obtained by performing synchronization processing with the mobile device 100 can be stored, and backup processing can be performed.

  In the present embodiment, the coupon data has an electronic value, and its function is to receive a predetermined service, receive a predetermined service, and purchase a product. Discounted charges may apply. By starting a predetermined application as described above, reading coupon data into the application, and communicating by performing short-distance communication with a reader / writer installed in the store and the non-contact type IC card 18, You can receive the above services.

  In addition, there are coupon data that can be redistributed (copy is possible) and coupon data that is not redistributable (cannot be copied). The present embodiment can be applied to any one, but the backup server 200 needs to be configured as follows when storing coupon data that cannot be redistributed. That is, since the copy of coupon data that cannot be redistributed is prohibited in principle, the backup server 200 is configured so that it cannot be transmitted to a mobile device that is different from the mobile device that acquired the coupon data. It is necessary to That is, the backup server 200 stores the individual number of the mobile device that acquired the coupon data together with the coupon data, and transmits the coupon data only to the mobile device having the stored individual number when attempting to redistribute. Need to be configured to be able to. Thereby, copy of coupon data can be prevented substantially and unauthorized use of coupon data can be prevented.

  On the other hand, the backup server 200 may be configured to automatically update coupon data stored in the mobile device 100. That is, the coupon data and the ID for specifying the content server are stored in association with the URL of the content server, and when a coupon data update request is received from the content server specified by the URL and ID, Update data. The update content here is, for example, updating coupon data with a expiration date to coupon data applied to a new expiration date. Thus, when new coupon data is acquired on the backup server 200 side, synchronization processing is performed in the processing in the synchronization protocol processing unit 202, and the same coupon data is also stored in the mobile device 100.

  Next, the operation of the backup system configured as described above will be described. FIG. 5 is a flowchart showing the operation of the backup system when backing up coupon data with a limited number of uses. First, in the mobile device 100, coupon data A with a limited number of uses is acquired (S101). And the synchronous process of coupon data is performed (S102). The synchronization process is performed immediately after the coupon data A is acquired, and the synchronization process is started by the user operating the data synchronization UI unit 102 of the mobile device 100 or the backup server 200 performs data synchronization. The starting point may be that the synchronization processing by the protocol processing unit 202 is started.

  In the mobile device 100, the coupon data A is used when the user operates the browsing / use unit 106 (S103). Then, the DRM processing unit 107 determines whether or not the use count of the coupon data A has exceeded the use limit (S104). For example, when the usage count reaches the total usage count, it can be determined that the usage limit has been exceeded. If it is determined that the usage limit has been exceeded, the DRM processing unit 107 moves the user data stored in the data storage unit 105 to the used folder (S105). Then, it is recorded in the data update history management unit 104 that the coupon data A has been used in the update history (S106).

  Thereafter, the data synchronization protocol processing unit 103 immediately performs synchronization processing (S107). The starting point may be that the synchronization process is started by the user operating the data synchronization UI unit 102 of the mobile device 100, or that the synchronization process by the data synchronization protocol processing unit 202 is started in the backup server 200. . At this time, information stored as update history information is transmitted to the backup server 200. For example, in S105 and S106, since the coupon data A is used and moved to the used folder, “coupon data A: DELETE” indicating that the coupon data A is deleted is transmitted to the backup server 200 (S107). .

  Then, in the mobile device 100, the update history information is cleared (S108). On the other hand, when the backup server 200 receives a notification to delete the coupon data A, the data synchronization protocol processing unit 202 deletes the coupon data stored in the data storage unit 203 (S202).

  Further, even when the coupon data A is used, if the usage limit is not exceeded (S104: NO), the DRM processing unit 107 adds one use count of the coupon data A stored in the data storage unit 105. And updated (S109). Then, in the data update history management unit 104, update history information is recorded as REPLACE as coupon data A, the number of uses thereof, and Sync information (S110).

  Thereafter, the data synchronization processing protocol processing unit 103 immediately performs synchronization processing (S111). As the timing of the synchronization processing, the synchronization processing is started by the user operating the data synchronization UI unit 102 of the mobile device 100, or the synchronization processing by the data synchronization protocol processing unit 202 is started in the backup server 200. May be the starting point. At this time, information stored as update history information is transmitted to the backup server 200. For example, in S110 and S111, since the coupon data A is used and the number of uses thereof is stored, the coupon data A indicating that the coupon data A, the number of uses, and the backup data are to be updated is displayed. Usable count): REPLACE "is transmitted to the backup server 200 (S111).

  Then, in the mobile device 100, the update history information is cleared by the data synchronization protocol processing unit 103 (S112). On the other hand, when the backup server 200 receives a notification indicating the number of uses of the coupon data A, the data synchronization protocol processing unit 202 updates the number of uses of the coupon data A stored in the data storage unit 203 (S203). .

  As described above, the coupon data A and the number of uses thereof can be transmitted from the mobile device 100 to the backup server 200, and the backup server 200 can store coupon data with a limited number of uses together with the number of uses. Coupon data with a limited number of times can be properly backed up without room for fraud.

  As a modification, when the process of S104 is NO, the process of S109 to S112 is executed without notifying the backup server 200 of the use state of the coupon data (the process of S111 is omitted). It is also possible. In this case, in S111, the synchronization processing is not started by reception of the data synchronization UI unit or the synchronization server trigger, and is omitted here.

  Moreover, when it is YES in S104, deletion of coupon data can be notified to the backup server 200 side by executing the processing of S105 to 108. As a result, the deletion process can be performed at the timing when coupon data exceeding the upper limit of the number of uses is present, and the traffic between the portable terminal 100 and the backup server 200 is reduced, thereby reducing traffic in the network. be able to. Note that in S107, as described above, the process of starting the synchronization process by receiving the data synchronization UI unit or the synchronization server trigger is omitted.

  In addition, every time the usage count is changed, the backup server 200 can be notified of the usage status (the usage count or the remaining available count). In this case, the browsing / use unit 106 needs to be configured to detect that coupon data is used and to instruct the data synchronization protocol processing unit 103 to perform usage state notification processing each time the coupon data is used. In this embodiment, notification is performed for each synchronization process, but fine management can be performed by performing notification processing at a fine timing such as notification every time a change is made. Also in this method, the mobile terminal 100 can notify the backup server 200 of deletion at the timing when coupon data whose number of uses has reached the upper limit exists.

  Next, a description will be given of a process for backing up coupon data having no use frequency limit and performing the synchronization process. FIG. 6 is a flowchart showing the operation of the backup system at that time.

  First, in the mobile device 100, coupon data E with no use frequency limit is acquired (S301). Thereafter, a synchronization process is performed (S302). By this synchronization processing, the coupon data E is stored in the data storage unit 203 of the backup server 200 (S401). Note that the synchronization process may be performed by a user operation of the data synchronization UI unit 102 or by a request from the backup server 200 as the timing of the synchronization process.

  Next, when the user operates the browsing / using unit 106, the coupon data E is deleted (S303). This is a process performed by the user when the user feels that the coupon data E is unnecessary, and is an arbitrary operation of the user. Then, a confirmation of deletion is displayed on the browsing / use unit 106 which is a coupon deletion UI (interface), and after confirmation by the user (S304), the data is stored in the data storage unit 105 by the browsing / use unit 106. The coupon data E is deleted (S305). After the deletion, the fact that the coupon data E is deleted is recorded in the data update history management unit 104 (S306).

  Thereafter, synchronization processing is performed by the data synchronization protocol processing unit 103 (S307). Note that the synchronization process may be performed by a user operation of the data synchronization UI unit 102 or by a request from the backup server 200 as the timing of the synchronization process. Since the coupon data E is deleted here, the data synchronization protocol processing unit 103 transmits “coupon data E: DELETE” indicating that to the backup server 200 from the mobile device 100 (S308). In the mobile device 100, the update history information in the data update history management unit 104 is cleared. On the other hand, when the backup server 200 receives a notification that the coupon data E is deleted, the coupon data E is received from the data storage unit 203. It is deleted (S402).

  Thereby, when user data is deleted, a deletion process will be performed and inconsistency of coupon data between the mobile device 100 and the backup server 200 can be prevented.

  Next, operational effects of the backup system including the mobile device 100 and the backup server 200 according to the present embodiment will be described.

  In the mobile device 100, the data storage unit 105 stores coupon data and usage status. Here, for example, coupon data is acquired by performing contact communication using the non-contact type IC card 18, and is stored together with its use state (whether it is at least used or may be used). Has been. As the initial state, the usage state is described as at least not being used, and the total number of available times may be described.

  The data update history management unit 104 uses the coupon data stored in the data storage unit 105 to communicate with an external terminal (a reader / writer for non-contact communication) installed in a store or the like. The usage status of the coupon data is recorded as used. Thereafter, the data synchronization protocol processing unit 103 notifies the backup server 200 of the recorded usage state. Thereby, the mismatch of the utilization state of coupon data between a backup server and a portable terminal can be prevented.

  In the present embodiment, the present invention is not limited to the non-contact type IC card 18, as long as it can perform near field communication such as infrared communication and Bluetooth and can be used without taking time and effort in the store. Good. In addition, the coupon data usage count and the total usage count are notified, but only the remaining usage count may be used, and information such as the usage count and the total usage count (including the remaining usage count) is also provided. Only when the coupon data is used up in the mobile device 100 without notification, it may be moved to the used folder and a notification of deletion may be transmitted to the backup server 200.

  Moreover, in the mobile device 100 of the present embodiment, for example, as soon as coupon data acquisition / update processing is performed at a predetermined timing with respect to the backup server 200 that stores coupon data, or user operation or In accordance with the request from the backup server 200, the data synchronization protocol processing unit 103 executes the synchronization processing of the coupon data and the usage state, and notifies the backup server 200 of the coupon data and the usage state in accordance with the synchronization processing. Therefore, it is possible to prevent inconsistency in the usage state of coupon data stored in the backup server 200 and the mobile device 100.

  Further, in the mobile device 100 of the present embodiment, the data synchronization protocol processing unit 103 notifies the usage status and the total usage count of the coupon data as the usage status, and the remaining usage count or the usage count and the total usage count. By notifying the number of times, the backup server 200 can grasp the remaining number of times coupon data can be used. Furthermore, since the detailed usage state such as the remaining number of usable times can be grasped in the backup server, unauthorized use by the user can be prevented.

  Further, in the mobile device 100 of the present embodiment, the data synchronization protocol processing unit 103 notifies the fact that the coupon data is deleted also in the backup server 200 by notifying that the coupon data is deleted as the usage state. be able to.

  Also, in the mobile device 100 of the present embodiment, when the coupon data is recorded as used in the data update history management unit 104, the data synchronization protocol processing unit 103 determines that the coupon data is used and uses it. The state is notified that the coupon data is to be deleted. As a result, even if no deletion operation is performed on the mobile device 100 side, if the coupon data is used up because there is no remaining usable number of coupon data, it is the same as the one without coupon data. The backup server 200 can appropriately reflect this. Therefore, inconsistency of coupon data between the mobile device 100 and the backup server 200 can be prevented.

  Moreover, in the backup server 200, the data storage unit 203 stores coupon data and backup data including the usage state. Then, when the data synchronization protocol processing unit 202 receives a notification of the coupon data usage state from the mobile device 100 via the data transmission / reception unit 201, the backup data stored in the data storage unit 203 is transferred to the usage state. In addition, the backup data can be rewritten. Thereby, also on the backup server 200 side, the usage state of the coupon data stored in the mobile device 100 can be grasped, and inconsistency in the usage state between the mobile device 100 and the backup server 200 is prevented. be able to.

  Further, in the backup server 200, when the data synchronization protocol processing unit 202 receives the fact that the coupon data is deleted from the mobile device 100 as the usage state, the coupon data stored in the data storage unit 203 is deleted. Inconsistency in the usage state between the mobile device 100 and the backup server 200 can be prevented.
