Abstract
A method is provided for determining whether a test object is an authentic object having an authentication image applied to an authentication image area thereof. The method comprises positioning and orienting a portable image acquisition device for selectively viewing and capturing a magnified image of a target surface area of the test object. The target surface area corresponds to the authentication image area of an authentic object. The method further comprises capturing a magnified digital image of the target surface area using the image capture acquisition device. The captured digital image is then processed to obtain a processed digital image and an authentication result is determined based on whether the processed digital image meets predetermined authentication criteria.
