Description

The present invention relates to a data processing apparatus capable of limiting the display mode of display information, a program thereof , and a data processing system .

  Conventionally, portable electronic information display media have been gradually reduced in weight and have been called electronic paper devices. And when such an electronic paper apparatus becomes widespread, information leakage from the electronic paper apparatus becomes a problem.

  For example, even at present, paper materials are distributed at a meeting and collected at the end. When the material is distributed by the electronic paper device, it is necessary to delete the material distributed to the electronic paper device of the conference participant.

As a technique that can cope with such a situation, a system that deletes information on a distribution destination from a distributor after a predetermined time (see Patent Documents 1 and 2), a system that can instruct deletion of information on a distribution destination (see Patent Document 3), An apparatus for erasing information when a specific radio wave cannot be received (see Patent Document 4), and an apparatus for erasing information when a predetermined area is left (see Patent Documents 5 to 7) have been devised.
JP 2003-076354 A Japanese Patent No. 3865112 JP 2006-072878 A JP 2004-037829 A JP 2007-286602 A JP 2006-227517 A JP 2006-039833 A

  However, these conventional techniques have the following problems.

  In the case of Patent Documents 1 and 2, there is a problem that it is not possible to cope with time changes. For example, in an actual meeting, there are many schedule changes such as time extension and time reduction.

  Further, in the case of Patent Document 3, there is a problem of false erasure due to disguised specific radio waves and communication trouble. For example, a person who wants to retain information may prepare a device that transmits a specific radio wave.

  In addition, in the case of Patent Document 4, there is a problem that display control cannot be performed when wireless communication cannot be performed (such as when the other party disables communication). For example, a person who wants to retain information can retain the information by ignoring the intention of the information provider by an operation such as blocking radio waves or turning off the terminal.

  Further, Patent Documents 5 to 7 have a problem of being influenced by surrounding infrastructure conditions (limited to a place where GPS radio waves can be received or a place where area specifying information can be received). For example, in the case where it is desired to delete the distributed material after the meeting, it is considered that there are many cases where the participant invites an external guest, or the material distributor goes to the partner's office as a guest. In such a situation, it is difficult to use devices / systems that depend on the surrounding infrastructure.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a data processing apparatus capable of providing information that can satisfy a meeting or a meeting application in a business, and a program thereof.

The data processing terminal device TM1 and the data processing terminal device TM2 correspond to the electronic paper device described above, and have an encrypted wireless communication function and can perform encrypted communication with each other.

  The wireless communication between the data processing terminal device TM1 and the data processing terminal device TM2 is realized by, for example, a so-called wireless LAN communication function or a PAN communication function such as BlueTooth, and a suitable protocol of P2P (Peer To Peer) as a protocol. Is used.

  As for encrypted communication, for example, in the case of wireless LAN communication, an encrypted communication method (for example, WEP, WPA, WPA2, etc.) in accordance with the so-called Wi-Fi standard can be applied. By adding an encryption communication protocol such as SSL to the communication protocol stack, more strict secure communication can be realized.

  FIG. 2 shows an example of the configuration of the data processing terminal device TM (TM1, TM2).

  In the figure, a CPU (central processing unit) 1 controls the operation of the data processing terminal device TM, and a ROM (read only memory) 2 is a program executed by the CPU 1 at startup and necessary data. RAM (Random Access Memory) 3 is for configuring a work area of the CPU 21 and the like.

The exchange of data between these elements is mainly performed via the internal bus 12.

  FIG. 3A shows an example of a storage area of the nonvolatile storage device 4.

  The nonvolatile storage device 4 includes arbitrary information such as own terminal electronic signature information set in the own terminal, partner terminal electronic signature information for identifying a partner terminal designated as a communication partner, display information, and the like. Is composed of an information storage area for storing data, and a system area used by the operating system of the data processing terminal device TM.

  In the case of the communication system of FIG. 1, the data processing terminal device TM1 on the display information providing side is in a stage before information is exchanged with the data processing terminal device TM2 on the display information receiving side. Display information is stored in the information storage area. As the display information, for example, image data such as conference materials, application document data, or the like is used. For example, the display information can be stored by downloading the display information stored in the USB memory MM using the USB host unit 10.

  Further, the partner terminal electronic signature information is stored in the data processing terminal devices TM1 and TM2 prior to mutual communication. The counterpart terminal electronic signature information can be stored via the USB memory MM in the same manner as the display information storage described above. Alternatively, the operation unit 8 can be directly operated for input.

  Further, as shown in FIG. 5B, the data processing terminal device TM1 includes disclosure confirmation interval information (disclosure data 1) indicating a display information disclosure confirmation time interval, and display information disclosure permission period. The disclosure permission period information (disclosure data 2) is also stored. The disclosure data 1 and 2 can be input by operating the operation unit 8, for example. Alternatively, display data 1 and 2 can be included in the display information.

  FIG. 4 shows an example of a connection procedure at the start of communication performed between the data processing terminal device TM1 and the data processing terminal device TM2.

  First, a communication path for wireless communication is established between the data processing terminal device TM1 and the data processing terminal device TM2. For example, the data processing terminal device TM1 first makes a connection inquiry to any surrounding data processing terminal device in order to construct an encrypted communication path for the wireless LAN communication function.

  Here, since the data processing terminal device TM2 can respond to the encrypted communication of the wireless LAN communication function, the confirmation response in the wireless LAN communication function is transmitted to the data processing terminal device TM1, thereby the data An encrypted communication path (encrypted communication link) for the wireless LAN communication function is established between the processing terminal device TM1 and the data processing terminal device TM2.

  Next, by applying the P2P session establishment procedure, the data processing terminal device TM1 establishes a communication session with the data processing terminal device TM2, and thereafter, the data processing terminal device TM1 and the data processing terminal device TM2 Communicate with each other using the established P2P communication session.

  Then, if necessary, the electronic signature information is exchanged, the stored counterpart terminal digital signature information is referred to, and each counterpart terminal is authenticated, thereby enabling secure communication thereafter.

  Further, for example, XML or the like can be adopted as the data format of information that the data processing terminal device TM1 and the data processing terminal device TM2 communicate with each other.

  With the above configuration, first, the data processing terminal device TM1 executes processing as shown in FIG. 5 to display the display information, and displays the display information and the disclosed data 1 as the counterpart terminal. Send to TM2.

  First, after displaying the display information (process 101), the data processing terminal device TM1 transmits the display information and the disclosure data 1 (disclosure confirmation interval information) to the data processing terminal device TM2 (process 102).

  When the display information display is prepared between the data processing terminal device TM1 and the data processing terminal device TM2 in this way, thereafter, the data processing terminal devices TM1 and TM2 are respectively shown in FIGS. Such processing is executed to display the display information.

  First, when the data processing terminal device TM1 receives the disclosure permission request from the data processing terminal device TM2 (the result of the determination 201 is YES), the data processing terminal device TM1 checks whether or not the current time is within the period of the disclosure permission period (decision 202).

  If the current time is within the disclosure permission period and the result of determination 202 is YES, display permission OK is transmitted to the data processing terminal device TM2 (process 203). If the current time is not within the disclosure permission period and the result of determination 202 is NO, display permission NG is transmitted to the data processing terminal device TM2 (process 204).

  On the other hand, when the data processing terminal device TM2 receives the display information from the data processing terminal device TM1, the data processing terminal device TM2 stores the display information in the nonvolatile storage device 4 (processing 301). Next, a display permission request is transmitted to the data processing terminal device TM1 (processing 302), and it is checked whether or not a display permission OK is received from the data processing terminal device TM1 (decision 303).

  When the display permission OK is received from the data processing terminal device TM1 and the result of the determination 303 is YES, the display information stored in the nonvolatile storage device 4 is displayed on the display unit 7 (processing 304).

  On the other hand, when the display permission response (display permission OK or display permission NG) cannot be received from the data processing terminal device TM1 and the result of determination 303 is NO, whether or not the transmission of the display permission request has been repeated a predetermined number of times. Check (determination 305). When the result of determination 305 is NO, it is checked whether display permission NG is received from the data processing terminal device TM1 (determination 306).

  If a display permission response cannot be received from the data processing terminal device TM1 and a time-out has occurred, and if the result of the determination 306 is NO, a display permission request is sent in step 302, and then the disclosure confirmation interval information is supported. The process waits until the elapsed time elapses (NO loop of determination 307), returns to process 302, and transmits a display permission request again.

  On the other hand, if the number of times that the display permission response has not been received in response to the transmission of the display permission request becomes a predetermined number and the result of determination 305 is YES, in this case, for example, the data processing terminal device TM1 In this case, the wireless communication with the data processing terminal device TM1 becomes impossible, or the power of the data processing terminal device TM1 is turned off. The display is erased and the display information stored in the nonvolatile storage device 4 is erased (process 308).

  When the display permission NG is received from the data processing terminal device TM1 and the result of the determination 306 is NO, the process proceeds to processing 308, and the display on the display unit 7 is erased and the non-volatile storage device 4 Delete display information saved in.

  Thus, after the display information and the display confirmation interval information are transmitted from the data processing terminal device TM1 to the data processing terminal device TM2, the data processing terminal device TM1 responds to the display confirmation request from the data processing terminal device TM2. Only when the display confirmation permission OK is returned, the data processing terminal device TM2 starts displaying the received display information.

  In this way, when display of display information is started, the data processing terminal device TM2 executes processing as shown in FIG. 8 to perform display information display continuation processing. In this case, the data processing terminal device TM1 executes the processing shown in FIG.

  That is, first, a display permission request is transmitted to the data processing terminal device TM1 (processing 401), and it is checked whether or not a display permission OK is received from the data processing terminal device TM1 (decision 402).

  When the display confirmation permission OK is received from the data processing terminal device TM1 and the result of determination 402 is YES, the display information stored in the nonvolatile storage device 4 is stored until the time corresponding to the disclosure confirmation interval information elapses. It is displayed on the display unit 7 (NO loop of processing 403 and determination 404). When the time corresponding to the disclosure confirmation interval information elapses and the result of determination 404 is YES, the process returns to process 401 and the display permission request is transmitted again.

  On the other hand, if the display permission response cannot be received from the data processing terminal device TM1 and the result of determination 402 is NO, it is checked whether or not the transmission of the display permission request has been repeated a predetermined number of times (determination 405). When the result is NO, it is checked whether display permission NG is received from the data processing terminal device TM1 (decision 406).

  If the display permission response cannot be received from the data processing terminal device TM1 and a timeout has occurred, and if the result of the determination 406 is NO, the display permission request is transmitted in the process 401, and then the disclosure confirmation interval information is supported. The display information stored in the nonvolatile storage device 4 is displayed on the display unit 7 until the elapsed time elapses (NO loop of processing 407 and determination 408). When the time corresponding to the disclosure confirmation interval information elapses and the result of determination 407 is YES, the process returns to process 401 and the display permission request is transmitted again.

  On the other hand, when the number of times that the display permission response has not been received in response to the transmission of the display permission request becomes a predetermined number, and the result of the determination 405 is YES, in this case, for example, the data processing terminal device TM1 In this case, the wireless communication with the data processing terminal device TM1 becomes impossible, or the power of the data processing terminal device TM1 is turned off. The display is erased and the display information stored in the nonvolatile memory device 4 is erased (process 409).

  When the display permission NG is received from the data processing terminal device TM1 and the result of the determination 406 is NO, the process proceeds to processing 409, the display on the display unit 7 is erased, and the non-volatile storage device 4 Delete display information saved in.

  In this way, in the present embodiment, display of display information on the data processing terminal device TM2 is permitted only during a disclosure permission period set in advance. It can be set appropriately.

  Further, after the preset disclosure permission period has elapsed, the data processing terminal device TM1 returns a display permission NG to the data processing terminal device TM2, and the display of display information in the data processing terminal device TM2 ends. At the same time, since the display information is erased from the nonvolatile storage device 4 in the data processing terminal device TM2, it is possible to prevent the user of the data processing terminal device TM2 from taking the display information carelessly.

  In addition, when the number of times that the data processing terminal device TM2 cannot receive the display permission response to the display permission request reaches a predetermined number, the data processing terminal device TM2 erases the display of the display information and also stores the nonvolatile information at that time. Since the display information is erased from the device 4, it is possible to prevent the user of the data processing terminal device TM2 from taking the display information carelessly.

  FIG. 9 shows another example of processing of the data processing terminal device TM1. In this case, the data processing terminal device TM2 performs the processing of the display information by executing the processing of FIGS.

  First, when the data processing terminal device TM1 receives a disclosure permission request from the data processing terminal device TM2 (the result of the determination 501 is YES), the data processing terminal device TM1 checks whether or not display information is displayed on the display unit 7 of the own terminal (determination 502). ).

  When the display information is displayed on the display unit 7 of the terminal itself, and the result of determination 502 is YES, display permission OK is transmitted to the data processing terminal device TM2 (process 503). Further, if the display information is not displayed on the display unit 7 of the terminal itself, and the result of determination 502 is NO, display permission NG is transmitted to the data processing terminal device TM2 (process 504).

  Therefore, in this case, the display information is displayed on the data processing terminal device TM2 only during the period in which the display information is displayed on the data processing terminal device TM1. When the display of the display information is finished in the data processing terminal device TM1, the display of the display information in the data processing terminal device TM2 is finished, and the display information is erased from the nonvolatile storage device 4 in the data processing terminal device TM2. Therefore, it is possible to prevent the user of the data processing terminal device TM2 from taking out display information carelessly.

  By the way, in the embodiment described above, when the display information is erased by the data processing terminal device TM2, all contents are erased. For example, mask information for setting the display information to be excluded from the erasure target is defined. The information element masked with the mask information may not be erased.

  By defining the mask information in this way, for example, it is possible to leave a display history (such as a title) on the data processing terminal TM2 side, which is convenient when it is desired to manage the usage history.

  In the above-described embodiment, the case where the present invention is applied to a communication system constructed with one terminal for providing display information and one terminal for receiving display information has been described. The present invention can be similarly applied to a communication system constructed by setting a plurality.

  In the above-described embodiments, electronic signature information is used as information to be referred to when performing mutual authentication between terminals. However, other appropriate identification information (for example, serial information) may be applied. it can.
