Abstract (en)

[origin: WO2009158324A1] An image acquisition device is provided for use in determining whether a test object is an authentic object having an authentication image applied to an authentication image area thereof. The authentication image includes indicia formed based on authentication parameters. The image acquisition device comprises an image capture arrangement configured for capturing a digital image of a target area of a test object. The image acquisition device further comprises a data processor having an image processing portion configured for receiving and processing the digital image to produce a processing result. The processing result may be established at least in part using one or more of the authentication parameters.
