To simply order printing while protecting privacy.

The image of each frame of a photographic film 48 is read by the image pickup part 51 of a film scanner 11. This read image of each frame is displayed in a list on a color monitor 12. This image displayed in a list is observed to specify a printing object frame. A print size and the number of prints with respect to the printing object frame is inputted by a keyboard 60 and a mouse 61. A ciphering processing part 39 ciphers image data by using ciphering key data. This ciphered image data are transferred to a print finishing dealer 13 with print ordering data. The dealer 13 composes image data by using ciphering key data to obtain original image data. Printing is executed based on print ordering data by using this image data. This print is sent to a user. As ciphered key data is magnetically recorded in the transparent magnetic recording layer of the film 48 and transferred to an opposite side, the secrecy of a ciphering key is kept.
