When the reading side terminal device 2 is configured by the computer 900, the input unit 230 realizes its function by the input device 906, and the output unit 240 realizes the function by the output device 905.

Further, as described above, the processing of each component of the reading-side terminal device 2 may be executed by a plurality of hardware such as client terminal devices.

FIG. 5 is a flowchart showing an example of user data storage request processing of the reading-side terminal device 2 in the first embodiment. The process of this flowchart is started when the reading side terminal device 2 is activated, for example.

First, the input unit 230 receives an archive request for user data (step S11). The input unit 230 receives an input of an archive request specifying the user data stored in the user data storage unit 201. The specified user data can be executed using an application of the reading-side terminal device 2.

Next, the user data acquisition unit 214 acquires the user data specified in the archive request from the user data storage unit 201 (step S12).

Next, the user environment information acquisition unit 212 acquires user environment information that is information related to the application and OS that the reading-side terminal device 2 has, and stores it in the user environment information storage unit 203 (step S13). The user environment information acquisition unit 212 identifies an application that executes the user data acquired in step S12, and stores the name and version in the application information storage unit 2031. In addition, the user environment information acquisition unit 212 identifies an OS that operates the application, and stores the OS in the OS information storage unit 2035.

Next, the reproducibility verification information generation unit 211 generates reproducibility verification information (step S14). The reproducibility verification information generation unit 211 refers to the extension related information storage unit 2034 using the extension of the specified user data, and specifies a reproducibility verification method associated with the extension. The reproducibility verification information generation unit 211 generates reproducibility verification information by the specified verification method and stores it in the reproducibility verification information storage unit 202.

For example, when the extension-related information includes a limitation on the range of reproducibility verification information generated for user data, the reproducibility verification information generation unit 211 specifies a range specified by the extension of the specified user data. Generate reproducibility verification information. For example, when the extension-related information includes information indicating that two pages from the beginning of the generated information are the reproducibility verification information, the reproducibility verification information generation unit 211 performs the reproducibility verification according to the range. Generate information.

If reproducibility verification information cannot be generated by the specified reproducibility verification method, for example, data obtained by outputting user data in a format compliant with an international standard such as a PDF file may be used as reproducibility verification information.

Next, the communication unit 220 transmits the user data acquired in step S12, the user environment information acquired in step S13, and the reproducibility verification information generated in step S14 to the saved data management apparatus 1 (step S15). . Then, the control part 210 complete | finishes the process of this flowchart.

The stored data management apparatus 1 receives the received user data, user environment information, and reproducibility verification information, respectively, as a user data storage unit 101, a user environment information storage unit 103, and a reproducibility verification information storage unit 102. And remember. Further, the verification result 104 a is generated by associating the received information, and stored in the verification result storage unit 104. After the completion of this process, the user data may be deleted from the storage unit 200 of the reading side terminal device 2.

First, the reproducibility verification unit 114 monitors the update of the user environment (step S21).

Next, the reproducibility verification unit 114 determines whether or not the user environment has been updated (step S22). When receiving a notification indicating that the environment information has been changed from the user environment monitoring unit 213 of the reading-side terminal device 2, the reproducibility verification unit 114 determines that the user environment has been updated. The update of the user environment includes, for example, an OS version upgrade and an application version upgrade. When the reproducibility verification unit 114 does not determine that the user environment has been updated (“NO” in step S22), the reproducibility verification unit 114 repeats the process of step S21 and continues to monitor the update of the user environment.

When the reproducibility verification unit 114 determines that the user environment has been updated ("YES" in step S22), the user environment information reception unit 112 acquires user environment information (step S23). The user environment information receiving unit 112 requests the reading side terminal device 2 for environment information. Upon receiving the request, the user environment information acquisition unit 212 of the reading side terminal device 2 acquires the environment information and transmits it to the stored data management device 1.

The user environment information receiving unit 112 stores the received environment information in the user environment information storage unit 103. Note that the user environment information receiving unit 112 compares the stored environment information with the environment information having the closest update date and time, and specifies the part where the environment information is updated (for example, the version of a specific application).

Next, the reproducibility verification unit 114 specifies user data for generating reproducibility verification information (step S24). The reproducibility verification unit 114 identifies any user data stored in the user data storage unit 101, for example.

It should be noted that the reproducibility verification unit 114 specifies user data executed by the update part specified in step S23 by referring to the extension related information storage unit 1034, and specifies one of the user data. Good. For example, when a specific application is updated, the reproducibility verification unit 114 may specify user data executed by the updated application as a verification target. In addition, the reproducibility verification unit 114 may specify one of user data generated in a predetermined period corresponding to a generation period of user data stored in the extension related information storage unit 1034. .

Next, the reproducibility verification unit 114 acquires the execution result of the user data (step S25). The reproducibility verification unit 114 outputs an execution request indicating the user data specified in step S24 to the reading-side terminal device 2. The control unit 210 of the reading-side terminal device 2 executes user data under the updated processing environment. When the specified user data is not stored in the reading side terminal device 2, the user data acquisition unit 214 requests the saved data management device 1 for user data, thereby acquiring user data. Thereafter, the control unit 210 transmits an execution result indicating whether or not the execution was possible to the saved data management apparatus 1.

The control unit 210 of the reading-side terminal device 2 determines that execution is impossible when information indicating a predetermined error is output when user data is executed. Alternatively, the control unit 210 determines that the execution is impossible when there is access to an application for executing the user data more than once in a predetermined period. When the reproducibility verification unit 114 acquires an execution result that specifies that the reproducibility is impossible, the reproducibility verification unit 114 determines that there is no reproducibility in a reproducibility verification process described later.

Further, the reproducibility verification unit 114 may determine whether or not the stored data management device 1 can execute user data under the same processing environment as that of the updated reading-side terminal device 2. In the stored data management device 1, when user data can be executed in the same environment as the updated reading-side terminal device 2, the reproducibility verification unit 114 uses the application of the stored data management device 1 to store user data. Execute and get the execution result. In this case, the reproducibility verification unit 114 does not output an execution request to the reading side terminal device 2.

Next, the reproducibility verification information acquisition unit 113 acquires reproducibility verification information in the updated environment (step S26). The reproducibility verification information acquisition unit 113 transmits a reproducibility verification information generation request specifying the user data to the reading-side terminal device 2. The reproducibility verification information generation unit 211 of the reading-side terminal device 2 generates reproducibility verification information under the updated processing environment and transmits it to the stored data management device 1. Note that the reproducibility verification information acquisition unit 113 determines whether or not the reproducibility verification information can be generated under the same processing environment as that of the updated reading-side terminal device 2. The reproducibility verification information generated in the device 1 may be acquired.

Note that the reproducibility verification information acquisition unit 113 refers to the extension related information storage unit 1034 for the user data specified in step S24, and specifies the verification method associated with the extension of the user data. For example, when the information indicating the generation range of the reproducibility verification information is associated with the extension of the user data, the reproducibility verification information acquisition unit 113 displays the reproducibility verification information generated in the range corresponding to the generation range. get.

Also, for example, when a script or tool for checking the operation of a special function included in an application that executes user data is associated with the extension of user data in the extension related information storage unit 1034, the reproducibility verification information acquisition unit 113 Acquires the check result as reproducibility verification information.

For example, when the user data is data generated using a spreadsheet application and the extension-related information storage unit 1034 is associated with information indicating that the macro program needs to be checked, the reproducibility verification information The acquisition unit 113 requests the reading side terminal device 2 to check the macro program. The reproducibility verification information generation unit 211 of the reading-side terminal device 2 transmits information indicating the execution result of the macro program to the stored data management device 1 as reproducibility verification information.

In addition, when the user data can include a link such as a URL, information indicating that the link needs to be checked can be associated with the extension related information storage unit 1034. In this case, the reproducibility verification information acquisition unit 113 searches the character string indicating the URL or the tag information to check the presence / absence of the link and the link check when there is a link. To request. The reproducibility verification information generation unit 211 of the reading-side terminal device 2 verifies reproducibility by accessing the link destination of user data. The reproducibility verification information generation unit 211 transmits information indicating the access result to the link destination to the stored data management apparatus 1 as reproducibility verification information.

Next, the reproducibility verification unit 114 verifies reproducibility (step S27). The reproducibility verification unit 114 refers to the verification result 104a using the user data specified in step S24, relates to the user data 104b, and reproducibility verification information 104g related to the verification result 104i indicating that the user data 104b can be reproduced. Is identified.

Note that whether or not the data can be reproduced can be determined by referring to the reference value of the extension related information storage unit 1034 related to the user data 104b. Further, when there are a plurality of reproducibility verification information 104g related to the verification result 104i indicating reproducibility, for example, the reproducibility verification information 104g with the oldest verification date 104h is identified among the reproducibility verification information 104g. To do. Note that the reproducibility verification information 104g with the latest verification date 104h may be specified.

The reproducibility verification unit 114 calculates the similarity between the specified reproducibility verification information and the reproducibility verification information acquired in step S26. The similarity is calculated by using a known method, for example, dividing the reproducibility verification information into meshes, extracting feature amounts for each mesh, or performing comparison at a binary level.

Next, the reproducibility verification unit 114 determines whether or not reproduction is possible (step S28). The reproducibility verification unit 114 determines that reproduction is not possible when an execution result indicating that execution is impossible is obtained in step S25. When the reproducibility verification unit 114 acquires an execution result indicating that execution is possible, the reproducibility verification unit 114 compares the reproducibility verification information to determine the presence or absence of reproducibility. The verification result registration reference unit 115 associates the user data used for verification of reproducibility, the environment information, the reproducibility verification information acquired in step S26, the verification date and the similarity, and generates a verification result 104a. And stored in the verification result storage unit 104.

Specifically, the reproducibility verification unit 114 specifies a reference value for the specified user data by referring to the extension related information storage unit 1034, and the similarity calculated in step S27 is greater than or equal to the reference value. Then, it is determined that the reproduction is possible. When the reproducibility verification unit 114 determines that reproduction is possible (in the case of “YES” in step S28), the control unit 110 advances the processing to step S30.

When the reproducibility verification unit 114 determines that the reproduction is impossible (in the case of “NO” in step S28), the verification result notification unit 116 notifies the reproducibility reduction (step S29). The verification result notifying unit 116 transmits a notification specifying the user data that has been verified for reproducibility to the reading-side terminal device 2. Note that the notification may specify information indicating the updated portion specified from the environment information acquired in step S23.

Further, the verification result notifying unit 116 uses environment information (application name 104c, application version 104d, OS name 104e, OS version 104f) associated with the reproducibility verification information 104g used for reproducibility verification in step S27. The reproducibility result information indicating that reproducibility was possible may be specified and transmitted to the reading-side terminal device 2. Thereby, the user who browsed the notification displayed on the reading-side terminal device 2 can recognize a processing environment in which user data that cannot be reproduced due to the update can be reproduced.

Further, the verification result notifying unit 116 refers to the verification result 104a using the updated environment information of the reading-side terminal device 2 acquired in step S23, and specifies the data format of the user data 104b related to the environment information. A notification suggesting a change to the data format may be performed. This makes it possible to recognize a data format that can be reproduced in the updated processing environment.

Next, the reproducibility verification unit 114 determines whether there is other target user data (step S30). As described above, the extension related information storage unit 1034 stores limiting conditions for user data to be verified for reproducibility. For example, when the reproducibility verification unit 114 refers to a limiting condition for verifying all user data stored in the user data storage unit 101, the reproducibility verification unit 114 is stored in the user data storage unit 101. The processing from step S24 to step S30 is repeated with all user data as verification targets.

Further, when the limiting condition for verifying all user data executed by the update part is stored, the update part specified in step S23, for example, identification information indicating a specific application version is specified. When the reproducibility of user data is reduced by updating the processing environment, the reproducibility of other user data executed in the updated processing environment may be reduced. Therefore, the reproducibility verification unit 114 repeats the processing from step S24 to step S30 until the verification is completed for the user data that is executed by the specified update portion and the reproducibility is not verified.

If the generation period of user data is stored as a limiting condition, the processing from step S24 to step S30 is repeated for the user data generated during the generation period.

Further, when the number of user data to be verified according to the update frequency of the environment information is stored as the limiting condition, the reproducibility verification unit 114 selects the environment information corresponding to the update portion in the user environment information acquired in step S23. And the update frequency of the environmental information is specified. The reproducibility verification unit 114 specifies the update frequency of the specified environment information and the number of user data files associated in the storage unit 100, and repeats the processing from step S24 to step S30 until the number of user data is reached. By setting a large number of user data to be verified for applications with a high update frequency, frequently updated applications can be verified more focused.

Further, when it is determined in step S28 that reproduction is impossible and notification is given to the reading-side terminal device 2 in step S29, user data having the same data format as the user data that cannot be reproduced is set as a verification target. Limit conditions can be set. In that case, the reproducibility verification unit 114 repeats the processing from step S24 to step S30 for other user data having the same data format as the user data determined to be impossible to reproduce.

Further, a limitation condition may be stored in which the user data once specified as the verification target and the environment information related to the verification result 104a are specified, and other user data associated with the specified environment information is not extracted. In that case, the reproducibility verification unit 114 repeats the processing from step S24 to step S30 for user data associated with environment information not common to the specified environment information.

When the reproducibility verification unit 114 determines that there is no other target user data (in the case of “NO” in step S30), the reproducibility verification unit 114 ends the processing of this flowchart.

According to the present embodiment, when the processing environment of the reading-side terminal device 2 is changed, it is possible to efficiently determine whether or not user data can be reproduced. Further, since the verification method and the verification target limiting conditions are determined according to the processing environment, reproducibility verification suitable for the changed processing environment can be performed.

In addition, since the reading-side terminal device 2 receives a notification when reproduction is impossible, it is possible to take appropriate measures for reproducing user data. For example, user data can be reproduced by taking measures such as returning the processing environment of the terminal device 2 on the reading side to the state before the update, coexisting the environment before and after the update, or virtually saving the environment before the update. It is possible to prevent it from becoming impossible.

In the user data storage request process of the reading side terminal device 2 shown in FIG. 5, when an archive request is accepted (step S11), the reproducibility verification information generation unit 211 generates reproducibility verification information (step S14). The reproducibility verification information thus stored is stored in the saved data management apparatus 1. However, the reproducibility verification information generation timing is not limited to this timing.

For example, the user environment monitoring unit 213 of the reading side terminal device 2 may detect the input of the update request of the reading side terminal device 2 and generate reproducibility verification information before the processing environment is updated. Thereafter, when the processing environment of the reading-side terminal device 2 is updated, the reproducibility verification process shown in FIG. 6 is executed. Thereby, since reproducibility verification information is not generated for user data generated by an application that is not scheduled to be updated, the storage capacity of the saved data management apparatus 1 can be reduced.

Note that the reproducibility verification information may be generated based on the input of the reproducibility verification information generation instruction from the user before the archive request (step S11) shown in FIG. According to this, since the user can check the information used for verification of reproducibility before transmitting it to the stored data management apparatus 1, it is possible to perform reproducibility verification with higher accuracy.

As described above, the present embodiment has been described using the example in which the reading-side terminal device 2 functions as a data center in the terminal solution. However, even if the stored data management system has a plurality of reading-side terminal devices 2 and each of the reading-side terminal devices 2 functions as a client terminal device operated by a user and has a different processing environment. Good.

In this case, the saved data management device 1 stores environment information in the user environment information storage unit 103 for each reading-side terminal device 2. When one reading-side terminal device 2 is updated, user data generated by another reading-side terminal device 2 having a different processing environment can be set as a verification target, so that user data to be verified is generated. The treated environment is varied. Therefore, even when a determination result indicating that there is no reproducibility is obtained, a reproducibility success record in a different processing environment can be notified as reproducibility result information, and an option can be given to the user.

As a result, the reading-side terminal device 3 is connected to the reading-side terminal device 2 described above. Similar functions can be realized.

The virtual environment information acquisition unit 312 acquires the virtual environment information stored in the virtual environment information storage unit 301 and transmits the virtual environment information to the saved data management apparatus 1 via the communication unit 320.

FIG. 9 is a flowchart illustrating an example of a user data storage request process according to the second embodiment. The processing performed from step S31 to step S35 is the same as the processing performed from step S11 to step S15 in the above-described embodiment. In addition,
The processing performed in steps S11 to S15 is executed by each processing unit of the reading side terminal device 2 as a virtual environment constructed on the reading side terminal device 3 by the virtual environment reproduction unit 311 reproducing the virtual environment. The For example, in step S <b> 32, the user environment information acquisition unit 212 of the reading terminal device 2 operating on the reading terminal device 3 acquires the user environment information of the reading terminal device 2. The acquired user environment information is transmitted to the saved data management apparatus 1 by the communication unit 220 in step S35.

Next, the virtual environment information acquisition unit 312 acquires virtual environment information, which is virtual environment execution information formed in the reading-side terminal device 3, from the virtual environment information storage unit 301, and transmits the virtual environment information to the stored data management device 1 ( Step S36). The virtual environment information receiving unit 117 of the saved data management apparatus 1 stores the received virtual environment information in the virtual environment information storage unit 105. Thereafter, the stored data management device 1 and the reading-side terminal device 3 end the processing of this flowchart.

FIG. 10 is a flowchart illustrating an example of a reproducibility verification process of the stored data management apparatus 1 according to the second embodiment. The process of this flowchart is started at the timing when both the stored data management device 1 and the reading-side terminal device 3 are activated, for example.

First, the reproducibility verification unit 114 monitors the update of the user environment (step S41).

It is determined that the user environment has been updated. The processing performed from step S41 to step S42 is the same as the processing performed from step S21 to step S22 shown in FIG.

Next, the virtual environment reproduction unit 118 of the stored data management device 1 constructs a virtual environment (step S43). Specifically, when an update of the virtual environment of the reading side terminal device 3 is detected, the virtual environment information receiving unit 117 requests the virtual environment information from the reading side terminal device 3. In response to the request, the virtual environment information acquisition unit 312 of the reading side terminal device 3 specifies the virtual environment information stored in the virtual environment information storage unit 301 and transmits the virtual environment information to the stored data management device 1. The virtual environment information receiving unit 117 of the saved data management apparatus 1 stores the received virtual environment information in the virtual environment information storage unit 105. The virtual environment reproduction unit 118 constructs an updated virtual environment using the virtual environment information. In other words, the virtual environment reproduction unit 118 reproduces the virtual environment formed in the reading side terminal device 3.

Thereafter, the processing performed from step S44 to step S51 is the same as the processing performed from step S23 to step S30 shown in FIG.

The reproducibility verification information acquisition unit 113 stores the generated reproducibility verification information in the reproducibility verification information storage unit 102. Thereafter, in step S48, the reproducibility verification unit 114 compares the reproducibility verification information generated in step S35 shown in FIG. 9 with the reproducibility verification information generated in step S47 of FIG. Verify reproducibility.

In step S50, the verification result notifying unit 116 notifies the reproducibility deterioration, but the notification may include reproducibility result information indicating that the reproducibility is possible. This is the same as the embodiment. In this case, the reproducibility result information includes user environment information of the reading-side terminal device 2 as a virtual environment determined to have reproducibility.

In the present embodiment, the reproducibility of the storage data stored in the storage data management device 1 is verified by the storage data management device 1 playing back the virtual environment constructed on the reading-side terminal device 3. The configuration example of the virtual environment is not limited to this embodiment.
