More Information
Summary:Unique Physical Unclonable (PUF) function objects may be created by molding or extruding specialized particles creating a measurable physical characteristic over a surface. The magnetized particles form a unique measurable magnetic "fingerprint" based on the random size, position, polar rotation, magnetization level, particle density, etc., of the particles. PUF objects may also vary in other physical characteristics by having a mixture of magnetic, conductive (magnetic or nonmagnetic), optically reflective or shaped, varied densities or mechanical properties resulting in random reflection, diffusion, or absorption of acoustical energy particles in a matrix or binder. The present invention envisions sensing any of the characteristics.
