1. An image processing method of processing a digital data as an object, which can exist temporarily or continuously in a falsification-vulnerable environment, so as to enable proof of authenticity thereof, the image processing method comprising:

  • a first extraction step of extracting from an unprocessed digital image, at least a part of the unprocessed digital image as processing object information;

    a first operation step of subjecting the processing object information to a first morphology operation using a predetermined first structuring element, to obtain first morphology image information;

    a first generation step of generating a processed digital image containing the first morphology image information; and

    a second operation step of subjecting difference information between the processing object information and the first morphology image information to a second morphology operation using a second structuring element different from the first structuring element, to obtain first morphology difference information,wherein the first generation step performs a logical subtraction operation between the first morphology image information and the first morphology difference information to generate the processed digital image.
