Description

The present invention relates to a client terminal end, and a program.

  In recent years, with the spread of the Internet, PCs (Personal Computers), mobile phones, and the like, there are many cases where personal information and the like are stored electronically, and information to be managed is enlarged.

  For example, various kinds of personal information such as a telephone directory, an address book, a schedule, a memo pad, and an e-mail are stored in a mobile phone. For this reason, when the mobile phone is lost, all of the personal information is lost.

  As a technique for solving this problem, a communication system is disclosed in which a mobile phone terminal and a charging device perform wireless communication using RFID (Radio Frequency IDentification), and personal information of the mobile phone terminal is backed up on the charging device. (See Patent Document 1).

  In addition, notebook PCs (notebook PCs) can be used in the same way as mobile phones, but in order to prevent the loss or leakage of information due to the loss of notebook PCs, various types of information can be registered in the server and the nearest network can be accessed. It is also used to access the server via

  Thus, when accessing a server from a notebook PC via a network, it is connected to a line or server used by a large number of users, so there is a risk of information leakage or tampering. Therefore, user authentication represented by a password is performed when connecting to the server.

[Transmission / reception data between server device and client portable terminal]
Next, data transmitted and received by short-range wireless communication between the server device 10 and the client portable terminal 20 will be described with reference to FIG.

  The client portable terminal 20 transmits a “request command” to the server device 10. Then, the server device 10 transmits “command response data” corresponding to the request command to the client portable terminal 20.

  There are four types of request commands: “LIST” command, “GET” command, “DEL” command, and “STORE” command.

  The “LIST” command includes a user identification code. The “LIST” command is a command for acquiring all registered data (registered data list) associated with the user identification code. When the server device 10 receives the “LIST” command from the client portable terminal 20, the server device 10 is associated with the user identification code included in the “LIST” command among the registration data registered in the registration data DB 142 of the server device 10 itself. The registered data and the number of registered data are transmitted as command response data to the client portable terminal 20.

  The “GET” command includes a user identification code and a data identification code. The “GET” command is a command for acquiring registration data associated with the user identification code and the data identification code. When the server device 10 receives the “GET” command from the client portable terminal 20, the user identification code and the data identification code included in the “GET” command among the registration data registered in the registration data DB 142 of the server device 10 itself. The registration data associated with is transmitted to the client portable terminal 20 as command response data.

  The “DEL” command includes a user identification code and a data identification code. The “DEL” command is a command for deleting registration data associated with the user identification code and the data identification code. When the server apparatus 10 receives the “DEL” command from the client portable terminal 20, the user identification code and the data identification code included in the “DEL” command among the registration data registered in the registration data DB 142 of the server apparatus 10 itself. Delete the registration data associated with. Then, when the deletion process is successful, the server device 10 transmits “OK” information to the client portable terminal 20 as command response data. If there is no registration data to be deleted or if the deletion process fails, the server device 10 transmits “NG” information to the client portable terminal 20 as command response data.

The “STORE” command is a command for registering new data or changing the contents of registered data (registered data). When the server device 10 receives the “STORE” command from the client portable terminal 20, the registration data associated with the user identification code and the data identification code (included in the registration data) included in the “STORE” command is stored in the local server. It is searched whether it is registered in the registration data DB 142 of the device 10. When there is corresponding registration data, the server device 10 overwrites the registration data included in the “STORE” command on the corresponding registration data. On the other hand, when there is no corresponding registration data, the server device 10 newly registers the registration data included in the “STORE” command in the server device 10 itself. When the server device 10 succeeds in overwriting or new registration, the server device 10 transmits “OK” information to the client portable terminal 20 as command response data. When overwriting or new registration fails, the server device 10 transmits “NG” information as command response data to the client portable terminal 20.

[Processes executed on the server]
Next, a specific operation of processing executed in the server device 10 will be described with reference to FIG. This process is performed in cooperation with the CPU 11 and the server program 141.

  As shown in FIG. 6, the CPU 11 of the server device 10 waits for reception of a request command from the client portable terminal 20 (step S1).

  When the user brings the client portable terminal 20 in the vicinity of the server device 10 and receives a request command from the client portable terminal 20 in the short-range wireless communication unit 13, the CPU 11 determines the type of the received request command. (Step S2).

  When the type of the request command is “LIST” command (step S2; LIST), the CPU 11 refers to the registered user management table T1, and “user” has the same user identification code as the user identification code included in the “LIST” command. Search for “definition”. The CPU 11 reads out the corresponding registered data management table T2 based on the “registered data management table storage destination” included in the searched “user definition”. The CPU 11 transmits the “number of registered data” of the read registration data management table T2 to the client portable terminal 20 via the short-range wireless communication unit 13 (step S3).

  Then, the CPU 11 refers to the read registration data management table T2, and reads out the corresponding registration data d1 based on the “registration data storage destination” included in each “registration data definition”. CPU11 transmits registration data d1 for the number of read registration data to client personal digital assistant 20 via near field communication part 13 (Step S4, Step S5; NO).

  When the CPU 11 transmits the registration data d1 for the number of registration data (step S5; YES), the CPU 11 again waits for reception of a request command from the client portable terminal 20 (step S1).

  Returning to step S2, if the type of the request command is “GET” command (step S2; GET), the CPU 11 refers to the registered user management table T1 and has the same user identification as the user identification code included in the “GET” command. Search for “user defined” with code. The CPU 11 reads out the corresponding registered data management table T2 based on the “registered data management table storage destination” included in the searched “user definition”. The CPU 11 refers to the read registered data management table T2 and searches for “registered data definition” having the same data identification code as the data identification code included in the “GET” command. The CPU 11 reads out the corresponding registration data d1 based on the “registration data storage destination” included in the searched “registration data definition”. The CPU 11 transmits the read registration data d1 to the client portable terminal 20 via the short-range wireless communication unit 13 (step S6). Then, the CPU 11 again waits for reception of a request command from the client portable terminal 20 (step S1).

  Returning to step S2, if the type of the request command is “DEL” command (step S2; DEL), the CPU 11 refers to the registered user management table T1 and has the same user identification as the user identification code included in the “DEL” command. Search for “user defined” with code. The CPU 11 reads out the corresponding registered data management table T2 based on the “registered data management table storage destination” included in the searched “user definition”. The CPU 11 refers to the read registered data management table T2 and searches for “registered data definition” having the same data identification code as the data identification code included in the “DEL” command (step S7).

  If there is a corresponding “registered data definition” as a result of the search (step S7; YES), the CPU 11 deletes the registered data d1 stored in the “registered data storage destination” included in the “registered data definition”. (Step S8). Specifically, the CPU 11 deletes the corresponding “registration data definition” from the read registration data management table T2. Then, the CPU 11 decreases the value of “number of registered data” in the read registered data management table T2 by one. Then, the CPU 11 transmits “OK” information to the client portable terminal 20 via the short-range wireless communication unit 13 (step S9). Then, the CPU 11 again waits for reception of a request command from the client portable terminal 20 (step S1).

  On the other hand, if there is no corresponding “registration data definition” as a result of the search (step S7; NO), the CPU 11 transmits “NG” information to the client portable terminal 20 via the short-range wireless communication unit 13 (step S7). S9). Then, the CPU 11 again waits for reception of a request command from the client portable terminal 20 (step S1).

  Returning to step S2, if the type of the request command is “STORE” command (step S2; STORE), the CPU 11 refers to the registered user management table T1 and “user” having the user identification code included in the “STORE” command. Search for “definition”. The CPU 11 reads out the corresponding registered data management table T2 based on the “registered data management table storage destination” included in the searched “user definition”. The CPU 11 refers to the read registration data management table T2 and searches for “registration data definition” having the same data identification code as the data identification code in the registration data included in the “STORE” command (step S10).

  As a result of the search, if there is a corresponding “registration data definition” (step S10; YES), the CPU 11 stores “registration data storage location” included in this “registration data definition” in the registration data d1. The registration data included in the “STORE” command is overwritten (step S11).

  On the other hand, if there is no corresponding “registration data definition” as a result of the search (step S 10; NO), the CPU 11 stores the registration data included in the “STORE” command in the auxiliary storage unit 14. Then, the CPU 11 generates a registered data definition in which the stored address of the stored auxiliary storage unit 14 is “registered data storage destination” and the data identification code of the registered data included in the “STORE” command is “data identification code”. And added to the registered data management table T2. That is, the CPU 11 newly registers registration data included in the “STORE” command (step S12). Then, the CPU 11 increments the value of “number of registered data” in the read registered data management table T2.

  When the processing of step S11 or step S12 is normally completed, the CPU 11 transmits “OK” information to the client portable terminal 20 via the short-range wireless communication unit 13 (step S13). On the other hand, when the process of step S11 or step S12 is not normally performed, the CPU 11 transmits “NG” information to the client portable terminal 20 via the short-range wireless communication unit 13 (step S13).

  Then, the CPU 11 again waits for reception of a request command from the client portable terminal 20 (step S1).

[Processes executed on client mobile devices]

  When the CPU 21 receives “NG” information as command response data from the server device 10 via the short-range wireless communication unit 26, the CPU 21 displays that fact on the display unit 24.

[Edit screen processing]
Next, a specific operation of the editing screen processing (step S111 in FIG. 7) will be described with reference to FIG.

  As shown in FIG. 8, when the new button b1 on the list screen 241 is pressed and the edit screen 242 is displayed (step S201; new), the CPU 21 issues a new data identification code, and the own client portable terminal Registration data including 20 user identification codes and the issued data identification code is generated (step S203).

  On the other hand, when any of the change buttons b4 on the list screen 241 is pressed and the edit screen 242 is displayed (step S201; change), the CPU 21 stores the user identification code of the own client mobile terminal 20 and the corresponding registration data. A GET command including the data identification code is generated and transmitted to the server device 10 via the short-range wireless communication unit 26. Then, the CPU 21 acquires (receives) registration data corresponding to the GET command from the server device 10 via the short-range wireless communication unit 26 (step S202).

  After the process of step S202 or step S203 is performed, the CPU 21 receives an operation signal from the operation unit 23 by a user operation on the editing screen 242. For example, the user performs a user operation for editing the registered actual data on the registered actual data editing area c3.

  When the registration button b6 on the editing screen 242 is pressed and an operation signal is input from the operation unit 23 (step S204; registration), the CPU 21 converts the registration actual data included in the generated or acquired registration data into the registration actual data. The character information displayed in the data editing area c3 is updated. Then, the CPU 21 generates a STORE command including the registration data and the user identification code of the own client portable terminal 20. The CPU 21 transmits this STORE command to the server device 10 via the short-range wireless communication unit 26, and registers the edited data in the server device 10 (step S205). Then, the CPU 21 returns to the process of step S201.

  When the reset button b7 on the editing screen 242 is pressed and an operation signal is input from the operation unit 23 (step S204; reset), the CPU 21 resets the character information being edited in the registered actual data editing area c3 ( Steps S201 to S204).

Communication is possible. The server device 10 stores the user identification code, the data identification code, and the registration data in association with each other in the registration data DB 142. The client portable terminal 20 generates a request command including the user identification code or including the user identification code and the data identification code, and transmits the request command to the server device 10. The server device 10 performs data processing related to the registration data in response to the request command based on the user identification code or the user identification code and the data identification code, and transmits command response data to the client portable terminal 20. The client portable terminal 20 displays command response data on the screen. Specifically, the client portable terminal 20 displays a registration data list, registration data, etc. according to the request command.

  That is, since only the server device 10 stores the registration data in the distributed data management system 100, even if the user loses the client portable terminal 20, the loss and leakage of personal information can be prevented.

  Further, since the registration data can be distributed and stored in the plurality of server apparatuses 10, the amount of information referred to by the user at a time using the client portable terminal 20 is reduced, and the information access speeds up. Therefore, a huge amount of information can be managed efficiently.

  In the distributed data management system 100, since short-range radio is used, it is impossible to intercept information from a distant place. Therefore, installing the distributed data management system 100 in the office eliminates the need for user authentication for accessing information such as passwords. Therefore, the troublesomeness of user authentication can be reduced, and further the cost of the system related to security can be suppressed.

  The description in the present embodiment is an example of the distributed data management system according to the present invention, and the present invention is not limited to this. The detailed configuration and detailed operation of the system and each device can be changed as appropriate.

  For example, the short-range wireless communication in the present embodiment employs the RFID standard, but is not limited to this.

  In this embodiment, an example in which a hard disk is used as a computer-readable medium storing a program is disclosed, but the present invention is not limited to this example. As other computer-readable media, a portable storage medium such as a CD-ROM, a non-volatile memory such as a flash memory, and the like can be applied. Also, a carrier wave can be applied as a medium for providing program data via a communication line.
