Abstract
Provided is an anti-counterfeit marking technique for verifying authenticity of objects using x-ray fluorescence (XRF) analysis.
Claims16
A method for marking and authenticating a metallic object, the method comprising
- applying a marking composition on at least a surface region of the metallic object, in an amount or in a pattern indicating authenticity,
- said marking composition comprising at least one XRF-sensitive marker in an amount between 0.1 and 10,000 ppm, at least one surface binding material, and at least one etchant;
- and
- irradiating said object with x-ray or gamma-ray radiation to detect an x-ray response signal and
- processing the detected x-ray response signal to obtain an enhanced response signal,
- wherein the enhanced response signal identifies at least one marker signal associated with the at least one XRF-sensitive marker, and at least one of (i) auxiliary signal associated with the at least binding material and (ii) a signal indicative of at least one of the metals present in the metallic object, to thereby determine object authenticity.
