Abstract

A method and system for authenticating an item by using a security marking. (12) The security marking (12) is provided on the item with an OVD ink capable of absorbing light in a visible wavelength range to appear visibly black and producing a red fluorescent emission under ultraviolet excitation. Under visible light illumination and ultraviolet excitation, a visible image (24) and a fluorescent image (22) are obtained from the security marking using image scanners (80). The images are compared to find a substantial match with each other. The security marking can be a postage indicium (12), a barcode (38), a symbol, a message or an image.
