Abstract
Appartus and methods of verifying objects utilize detectable characteristics of a plurality of spaced apart, magnetizable magnetic security regions affixed to the object. Magnetic characteristics for each magnetic region are detected from two different orientations. A verification apparatus senses the magnetic characteristics from two different orientations and compares it to a prestored representative profile previously created. Correspondence between the prestored profile and the currently read characteristics indicates an authentic object. Other objects can be rejected.
