A file provision method comprising: a file transmission step in which, if the file provision device successfully authenticates according to the authentication step, the file provision device transmits the data file generated by the file generation device to the requesting terminal.
7. In a file provision system including a file generation device and a file provision device that provides data files generated by the file generation device, A signature information generation step that generates signature information, provided that the requesting terminal requesting the data file is connected to the same network as the file generation device, A program that causes the computer of the file generation device to execute an authentication information transmission step, which transmits the authentication information generated in the authentication information generation step to the requesting terminal and the file provisioning device.

Description

This invention relates to a file provisioning system, a file provisioning method, and a program. For example, Patent Document 1 discloses an image processing system in which scanned data is stored in the storage 104 of a digital multifunction printer 103, a scan data processing module 502 transmits scan information about the digital multifunction printer 103 that performed the scan and the user who performed the scan to a management server 101, and a scan information management module 522 stores and manages the transmitted scan information. This allows the user to identify the storage location of their scan data from the management server 101 via a scan data acquisition module 541 from a client terminal 102, based on the scan information. The system then acquires the scan data from the multifunction printer 103 that performed the scan. Furthermore, Patent Document 2 discloses an image input device control device that controls a control unit and an image input device associated with the control unit via a network, characterized by comprising: authentication information acquisition means for acquiring authentication information; image data storage means for storing image data; storage area generation means for generating a storage area within the image data storage means in which access rights corresponding to the authentication information acquired by the authentication information acquisition means are set; and image acquisition means for acquiring the image data from the image input device and storing it in the storage area generated by the storage area generation means. Furthermore, Patent Document 3 discloses a communication system in which the scanner 10 receives both account information AC1 for logging into the intermediary server 50 and account information AC2 for logging into the storage server 100 from the mobile terminal 150 using a single NFC communication. The scanner 10 logs into the intermediary server 50 using account information AC1, and when it receives a scan instruction from the intermediary server 50, it transmits the scan data to the intermediary server 50. The scanner 10 then transmits account information AC2 to the intermediary server 50, with account information AC1 and AC2 associated. The intermediary server 50 then logs into the storage server 100 using account information AC2 and transmits the scan data to the storage server 100. Furthermore, Patent Document 4 discloses an image reading device comprising: a scan cloud ticket receiving unit that receives a scan cloud ticket, which is a data file storing the contents of a job for storing scan data generated by an image reading device on a cloud server using login information to a cloud server; a startup operation input unit that inputs a startup operation to start a job in response to the reception of the scan cloud ticket; a scan data generation unit that performs image reading and generates scan data in response to the startup operation input; a login processing unit that obtains login information from the scan cloud ticket and logs in to the cloud server using the obtained login information; and an upload processing unit that uploads scan data from the image reading device to the cloud server.
