IMAGE PROTECTION SYSTEM, IMAGING DEVICE, AND REPRODUCTION DEVICE

PROBLEM TO BE SOLVED: To provide a system capable of setting use restriction with respect to a subject image related to a work and setting no use restriction with respect to a normal subject image.SOLUTION: Imaging control means 30 of an imaging device 3 checks a mode that has been set by using mode setting means 34 when a subject image is stored in a secure memory card 2. The imaging control means 30 gives an instruction to write a subject image encrypted by using an encryption section 210 of a secure chip 21 to the secure memory card 2 in the case of a work mode, and gives an instruction to write a subject image without performing encryption to the secure memory card 2 in the case of a normal mode. When the mode of an image file 220 to be reproduced is a work mode, reproduction control means 40 of a reproduction device 4 performs personal authentication by using a personal authentication section 212 of the secure chip 21. Then, when personal authentication is successfully performed, the reproduction control means 40 gives an instruction to read a subject image decrypted by using a decryption section 211 of the secure chip 21 to the secure memory card 2.
