Abstract
The application concerns a method of authenticating an object, the object comprising an identification substance including at least one amorphous phase, at least one crystalline phase and at least one complex metallic phase. The method includes the steps of: subjecting the identification substance of a candidate object to XRD analysis to determine an XRD signature thereof; comparing the XRD signature of the candidate object to a reference XRD signature, and concluding to the authenticity of the object when its XRD signature substantially matches the reference XRD signature.
Claims22
A method of authenticating an object, the object comprising an identification substance including at least one amorphous phase, at least one crystalline phase and at least one complex metallic phase, said method comprising:
- subjecting the identification substance of a candidate object to X-Ray diffraction, XRD, analysis to determine an XRD signature thereof;
- comparing the XRD signature of the candidate object to a reference XRD signature, and concluding to the authenticity of the object when its XRD signature substantially matches the reference XRD signature.
A method of authenticating an object, said method comprising the steps of:
- a) manufacturing an identification substance including at least one amorphous phase, at least one crystalline phase and at least one complex metallic phase;
- b) subjecting an amount of said identification substance to X-Ray diffraction, XRD, analysis to determine an XRD signature thereof and storing the latter as reference XRD signature;
- c) associating an amount of said identification substance to an object;
- d) subjecting a candidate identification substance associated with an object to be identified to XRD analysis to determine an XRD signature of said identification substance;
- e) comparing said XRD signature of said candidate identification substance to said reference XRD signature, and concluding to the authenticity of said object to be identified when its XRD signature substantially matches said reference XRD signature.
An authentication method comprising analysing an X-Ray diffraction signature of an identification substance, wherein said identification substance comprises at least one amorphous phase, at least one crystalline phase and at least one complex metallic phase.
