## Abstract

Systems and methods subjecting a computer graphics object to a pseudo-random transformation to produce a surface-texture snapshot used to verify the authenticity of a host object. An example method includes generating a hash of a private manufacturer identifier, a product identifier, and a chain of ownership identifier and generating a three-dimensional surface using a first portion of the hash. The method also includes generating a texture pattern using a second portion of the hash and generating a surface-texture snapshot by mapping the texture pattern onto the three-dimensional surface. The surface-texture snapshot may be provided for imprinting on the host object. In some implementations, the surface-texture snapshot may be used as a first check in an authentication procedure.
