Abstract: System for determining authenticity of an object in which a light-source directs collimated or telecentric light toward an authentication-region on the object, which impinges on the authentication-region at a predetermined angle relative to the normal of a plane defined by the object, a portion of the light is reflected from the authentication-region and another portion of the light is scattered from the authentication-region, an imager, focused on the authentication-region, acquires a focused-image of the scattered-light, the image includes image-features related to surface-features-scattering-phenomena of the authentication region, the processor determines correspondence between part of the acquired image and a corresponding part of a stored-image corresponding to the authentication-region, the processor identifies the object as authentic when the acquired-image corresponds to the stored image, the processor identifies the object as non-authentic when the acquired-image does not corresponds the stored-image.
