  After the uploader logs in, in response to the instruction to upload the file stored in the storage unit 13 by operating the operation unit 12 on the file management screen displayed on the display unit 11 of the information processing apparatus 10. Then, the data sharing system 1 starts the file upload process shown in FIG.

  7 and 8 are flowcharts showing the file upload process.

  In the file upload process, in the information processing apparatus 10, the control unit 15 first reads a file to be uploaded from the storage unit 13 and transmits (uploads) the data from the communication unit 14 to the data storage server 20 via the network 50 (FIG. 7 step S1).

  In the data storage server 20, the control unit 23 receives a file transmitted from the information processing apparatus 10 via the network 50 (step S2), and stores it in the main folder 220 of the uploader (step S3).

  Subsequently, in the information processing apparatus 10, the control unit 15 determines whether or not file sharing is instructed by the app owner (step S4). If it is determined that file sharing is not instructed (step S4; No), the process waits in a loop until instructed.

  If it is determined that file sharing has been instructed (step S4; Yes), it is determined whether or not the file disclosure setting has been changed to "password setting" by the uploader and a viewing password has been set (step S4). S5).

  When it is determined that the file disclosure setting has not been changed to “password setting” by the uploader (step S5; No), only the sharing of the file uploaded in step S1 is transmitted from the communication unit 14 via the network 50. The storage server 20 is instructed (step S6).

  On the other hand, if it is determined that the file disclosure setting has been changed to “password setting” by the uploader (step S5; Yes), the uploader instructs to share the uploaded file in step S1, and The set browsing password is transmitted from the communication unit 14 to the data storage server 20 via the network 50 (step S7).

  In the data sharing server 20, the control unit 23 determines whether or not a browsing password has been received from the information processing apparatus 10 in response to an instruction to share a file from the information processing apparatus 10 via the network 50. (Step S8).

  If it is determined in step S8 that the browsing password has been received (step S8; Yes), the file saved in the main folder 220 in step S3 is moved to the shared folder (with password) 222 (step S9) and received. The browsing password thus stored is stored in association with the storage unit 22 in the URL of the shared folder (with password) 222 (step S10). Further, the control unit 23 generates print data of the shared card 30 including the logo-added two-dimensional code 31 indicating the URL of the shared folder (with password) 222 and the browsing password set in the file (step S11). .

  On the other hand, if it is determined in step S8 that the browsing password has not been received (step S8; No), the file saved in the main folder 220 in step S3 is moved to the shared folder (no password) 221. (Step S12 in FIG. 8). Further, the control unit 23 generates print data of the shared card 30 including the logo-added two-dimensional code 31 indicating the URL of the shared folder (no password) 221 (step S13).

  Then, the control unit 23 transmits the print data of the shared card 30 generated in step S11 or S13 from the communication unit 21 to the information processing apparatus 10 via the network 50 (step S14).

  In the information processing apparatus 10, the control unit 15 receives the print data of the shared card 30 transmitted from the data storage server 20 via the network 50 at the communication unit 14 (step S 15), and the print data received at the printing unit 16. Based on the above, the paper medium shared card 30 is printed and output (step S16).

  The shared card 30 printed in this way is distributed from the app owner to the user of the mobile communication terminal 40. Thereafter, in response to the user operating the operation unit 43 of the mobile communication terminal 40 to instruct the reading of the two-dimensional code 31 with the logo printed on the shared card 30, the control unit 45 In 41, the URL indicated by the logo-added two-dimensional code 31 is read and displayed on the display unit. In response to the user operating the operation unit 43 and instructing access to the URL displayed on the display unit 42, the data sharing system 1 starts the file browsing process shown in FIG.

  FIG. 9 is a flowchart illustrating an example of the file disclosure setting process.

  In the file disclosure setting process shown in FIG. 9, in the information processing apparatus 10, the control unit 15 first determines whether or not the file disclosure setting has been changed to “automatically delete after opening” by the uploader ( Step S41). When it is determined by the uploader that the file disclosure setting has been changed to “automatically delete after opening” (step S41; Yes), the file is saved in the shared folder (no password) 221 or the shared folder (with password) 222 The data storage server 20 is instructed from the communication unit 14 via the network 50 to erase the file that has been opened (step S42).

  In the data storage server 20, in response to an instruction to delete the file after browsing from the information processing apparatus 10 via the network 50, for example, a post-browsing deletion flag provided in the storage unit 22 is set. The on state is set (step S43).

  On the other hand, if it is determined by the uploader that the file disclosure setting has not been changed to “automatically delete after opening” (step S41; No), the file disclosure setting is “restricted to the number of publication days”. It is determined whether or not the number of days of publication has been set by changing to "Apply" (step S44).

  If it is determined by the uploader that the file disclosure setting has been changed to “limit the number of publication days” and the number of publication days has been set (step S44; Yes), the shared folder (no password) 221 or the shared folder (password) Yes) The number of days of publication of the file stored in 222 is notified from the communication unit 14 to the data storage server 20 via the network 50 (step S45).

  In the data storage server 20, the control unit 23 responds to the reception of the file release days from the information processing apparatus 10 via the network 50 by the communication unit 21, for example, in a release day timer provided in the storage unit 22. The communication unit 21 sets a timer initial value corresponding to the number of days of file disclosure (step S46).

  10 and 11 are flowcharts showing an example of the file browsing process.

  In the file browsing process, in the mobile communication terminal 40, the control unit 45 first accesses the URL displayed on the display unit 42 and stores it in the shared folder (with password) 222 and the shared folder (without password) 221. The file storage server 20 is instructed from the communication unit 44 via the network 50 to browse the file that has been read (step S21 in FIG. 10).

  In the data storage server 20, in response to an instruction to browse a file from the mobile communication terminal 40 via the network 50, the control unit 23 receives the URL accessed from the mobile communication terminal 40 as a shared folder ( By determining whether the URL is the URL of 221 without password or the URL of shared folder (with password) 222, the file instructed to browse is shared folder (with password) 222 and shared folder (without password) 221. It is discriminated which one is stored (step S22).

  When it is determined that the file instructed to browse from the mobile communication terminal 40 is stored in the shared folder (no password) 221 (step S22; No), the control unit 23 uses the shared folder ( Browsing of the file stored in the password 221 is permitted (step S23).

  On the other hand, when it is determined that the file instructed to browse from the mobile communication terminal 40 is stored in the shared folder (with password) 222 (step S22; Yes), the control unit 23 determines a predetermined browsing password. The display of the input screen is instructed from the communication unit 21 to the mobile communication terminal 40 via the network 50 (step S24).

  In the mobile communication terminal 40, the control unit 45 displays the browsing password input screen on the display unit 42 in response to an instruction to display the browsing password input screen from the data storage server 20 via the network 50 ( Step S25).

  Subsequently, the control unit 45 determines whether or not a browsing password is input by the user (step S26). When it is determined that the browsing password has not been input (step S26; No), the process waits in a loop until it is input.

  If the browsing password is input (step S26; Yes), the input browsing password is transmitted from the communication unit 44 to the data storage server 20 via the network 50 (step S27).

  In the data storage server 20, the control unit 23 receives the browsing password transmitted from the mobile communication terminal 40 via the network 50 at the communication unit 21 (step S 28), and the received browsing password is stored in the storage unit 22. It is determined whether or not it matches the browsing password stored in association with the shared folder (having a password) 222 (step S29).

  If it is determined that the browsing passwords do not match (step S29; No), the browsing of the file is not permitted, and the fact is notified from the communication unit 21 to the mobile communication terminal 40 via the network 50 (step S29). S30).

  On the other hand, if it is determined that the browsing passwords match (step S29; Yes), browsing of the file stored in the shared folder (with password) 222 by the mobile communication terminal 40 is permitted ( Step S31).

  After executing the processing of step S23 or S30, the control unit 23 determines whether or not the post-viewing deletion flag provided in the storage unit 22 is on (step S32 in FIG. 11). If it is determined that the post-browsing deletion flag is on (step S32; Yes), it is determined whether or not the file has been browsed (step S33), and until the user finishes browsing the file (step S33; No) Loop and wait.

  If it is determined in step S33 that the user has finished browsing the file (step S33; Yes), the browsed file is moved from the shared folder (with password) 222 or the shared folder (without password) 221 to the main folder 220. Then, browsing is restricted (step S34). Moreover, the control part 23 clears the deletion flag after browsing provided in the memory | storage part 22, and makes it an OFF state (step S35).

  FIG. 12 is a flowchart illustrating an example of a file disclosure management process.

  In the file disclosure management process shown in FIG. 12, in the data storage server 20, the control unit 23 first determines whether or not the disclosure date / time timer has expired (step S51), and if it has not expired (step S51). No), loop and wait. If it is determined that the disclosure date / time timer has expired (step S51; Yes), the file is moved from the shared folder (with password) 222 or the shared folder (without password) 221 to the main folder 220 to restrict browsing. (Step S52).

  As described above, according to the data sharing system 1 according to the present embodiment, the information processing apparatus 10 uploads a file to the data storage server 20, and the data storage server 20 When sharing is instructed, the file is saved in the shared folder (no password) 221. Further, when the uploader changes the file disclosure setting to “password setting” on the file management screen and sets the browsing password, the file stored in the shared folder (no password) 221 is saved in the shared folder (with password) 222. Move to.

  Subsequently, when the browsing password is not set, print data of the shared card 30 including the logo-added two-dimensional code 31 indicating the URL of the shared folder (no password) 221 is generated. On the other hand, when the browsing password is set, printing of the shared card 30 including the two-dimensional code 31 with a logo indicating the URL of the shared folder (with password) 222 and the browsing password set in the file. Generate data.

  Then, the data storage server 20 transmits the print data of the shared card 30 to the information processing apparatus 10 via the network 50, thereby generating information on the generation of the shared card 30 on which the logo-added two-dimensional code 31 and the browsing password are printed. Instructs the processing apparatus 10.

  On the other hand, the information processing apparatus 10 receives the print data of the shared card 30 transmitted from the data storage server 20 via the network 50, and generates the shared card 30 on which the logo-added two-dimensional code 31 and the browsing password are printed. .

  Then, the data storage server 20 responds to the fact that the mobile communication terminal 40 has accessed the URL of the shared folder (no password) 221 read from the logo-added two-dimensional code 31 printed on the shared card 30. (No password) Permits browsing of files stored in 221.

  In response to this, the data storage server 20 responds to the fact that the mobile communication terminal 40 has accessed the URL of the shared folder (with password) 222 read from the logo-added two-dimensional code 31 printed on the shared card 30. Then, the mobile communication terminal 40 is instructed to input the browsing password, and it is determined whether or not the browsing password input in response thereto matches the browsing password set in the file. When the browsing password determination unit determines that the browsing password matches, the data storage server 20 permits browsing of the file stored in the shared folder (with password) 222.

  As a result, the file uploader generates the shared card 30 on which the logo-added two-dimensional code 31 indicating the URL of the folder in which the file is stored is printed and distributes the shared card 30 to the user. A URL stored in the printed logo-added two-dimensional code 31 can be accessed to browse a file stored in the folder. Then, after browsing, the paper-based shared card 30 is discarded by discarding it. In this way, it can be discarded after each use without being used many times like a USB memory, etc., thus preventing file leakage as much as possible and enabling safe data sharing It can be. Further, since the shared card 30 is a paper medium, it can be made cheaper than a USB memory and can be disposed of as burnable waste.

  In addition, it is possible to further enhance the safety of data sharing by setting a browsing password for a file or restricting browsing of a file after browsing the file or after the publication date and time.
