摘要 |
PROBLEM TO BE SOLVED: To prevent contents of an image file (with verification data) from revising in compliance with an instruction from a control apparatus. SOLUTION: Imaging apparatuses 10A, 10B determine whether or not verification data (MAC or digital signature) are attached to an image file. When the image file is attached with the verification data, the imaging apparatuses do not revise contents of the image file even when the imaging apparatuses receive an instruction from a computer 30.
