Object verification system and method
TLDR
In this article, the magnetic properties of a randomly varying and detectable magnetic region are used for verifying an object's authenticity by saturating the magnetizable magnetic regions of the object with water.Abstract:
Apparatus and methods of verifying objects utilize an inherent randomly varying and detectable characteristics of a plurality of spaced apart, magnetizable magnetic regions affixed to the object. Detectability of the randomly varying magnetic characteristics can be enhanced by saturating the magnetic regions. A verification apparatus senses the randomly varying magnetic characteristics 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.read more
