As shown in FIG. 1, the image data providing system includes a server system 1 that transmits image data to the portable terminal 4 and a printed material production apparatus 2 that photographs a user to produce a printed material 3.

  The server system 1 includes a web server 1B and a database server 1C.

  The printed material production apparatus 2 is a box-type photography apparatus that shoots a user to generate a user image, and combines the user image and a template image to generate a composite image. In addition, the print production apparatus 2 generates a URL of a web page and a pass code for the user to later download the composite image data. Furthermore, the printed matter production apparatus 2 codes the generated URL to create a two-dimensional code.

  As shown in FIG. 2, the printed material production apparatus 2 prints the composite image 31, the two-dimensional code 32, the pass code 33, and the URL 34 on the photographic paper to produce the printed material 3.

  The printed matter production apparatus 2 encrypts the image data and pass code of the composite image 31 and transmits them together with the URL information to the web server 1B. The print production apparatus 2 shares a common key (secret key) with the web server 1B, and encrypts image data and a passcode using this common key. HTTPS (Hypertext Transfer Protocol Secure) is used as a communication protocol between the web server 1B and the printed material production apparatus 2. That is, HTTP communication is performed over a secure connection provided by the SSL / TLS protocol.

  When the web server 1B receives the encrypted passcode from the print production device 2, it decrypts it using the common key. The web server 1B stores the encrypted image data, the decrypted passcode, and the URL information in the database server 1C. The database server 1C associates and saves URL information, a pass code, and image data. In the database server 1C, the image data is stored in an encrypted state.

  The user has a portable terminal 4 such as a smartphone or a tablet device, and a program for reading a two-dimensional code (two-dimensional code reading application) is stored in the portable terminal 4. When the portable terminal 4 executes this program, the camera function of the portable terminal 4 is activated to read the two-dimensional code. When the user captures the two-dimensional code 32 on the printed matter 3 with the camera of the portable terminal 4, the portable terminal 4 reads the two-dimensional code 32 to acquire the URL, and accesses the web server 1B. HTTPS is used as a communication protocol between the web server 1B and the portable terminal 4.

  When accessed from the mobile terminal 4, the authentication processing unit 13 requests input of a passcode. When receiving the passcode transmitted from the mobile terminal 4, the authentication processing unit 13 refers to the passcode held by the database server 1C and performs user authentication processing. When the passcode corresponding to the URL when the mobile terminal 4 has accessed and the passcode transmitted from the mobile terminal 4 match, the authentication processing unit 13 authenticates that the user is an authorized user.

  The data transmission processing unit 14 acquires encrypted image data corresponding to the URL when the mobile terminal 4 has accessed from the database server 1C. The data transmission processing unit 14 decrypts the encrypted image data by using a common key shared with the print production apparatus 2 and transmits the image data to the portable terminal 4.
