Abstract
An image verification apparatus includes a verification unit and a control unit. The verification unit verifies, using verification data included in an image file, whether a digital image included in the image file has been altered. The control unit (a) controls the image verification apparatus to display additional information of the digital image on a display unit, if the verification unit verifies that the digital image has not been altered, and (b) controls the image verification apparatus not to display the additional information except a thumbnail image of the digital image on the display unit and to display both the thumbnail image of the digital image and information indicating that the digital image has been altered on the display unit, if the verification unit verifies that the digital image has been altered. The additional information includes the thumbnail image of the digital image.
