Tagging and authentication of articles

A system for uniquely tagging and verifying authenticity of an article comprising:

• an object having a surface;
• a computer system adapted to:
• receive a three-dimensional predetermined image,
• create a holographic interference pattern created according to the three-dimensional predetermined image and at least one physical property of the surface of the object, wherein the holographic interference pattern is applied to the object,
• receive a three-dimensional resulting image that is projected on a planar surface in response to the holographic interference pattern being illuminated;
• and,
• create validation information according to a comparison of the three-dimensional predetermined image and the three-dimensional resulting image.

A system for uniquely tagging and verifying authenticity of an article comprising:

• an object having a holographic interference pattern and identifier disposed on a substrate affixed to a surface of the object;
• a three-dimensional predetermined image;
• and,
• a computerized system adapted to create the holographic interference pattern according to the three-dimensional predetermined image and a curvature, illuminate the holographic interference pattern with a coherent light source, produce a three-dimensional resulting image according to an illumination of the holographic interference pattern and create validation information according to a comparison of the three-dimensional predetermined image and the three-dimensional resulting image.
