Abstract:
1. A method for verifying the authenticity of a component, the method comprising: embedding an identification tag below a surface of the component, the identification tag having a selected geometric shape and composed of a polymer type material that returns an increased amount of backscattered radiation in comparison to the component; illuminating the component using low energy soft X-rays to penetrate only to a certain penetration depth of the component by a low energy X-ray source, said identification tag being within said certain penetration depth, and said certain penetration depth being above internal structures in said component that are sensitive to X-ray energy; receiving returned backscattered radiation of said low energy soft X-rays from said identification tag and from said component by one or more detectors; detecting a presence of said identification tag from an increased amount of said returned backscattered radiation from said identification tag in comparison to backscattered radiation from said component by said one or more detectors; and authenticating the component based on said detected presence of said identification tag.
