In a general aspect, orientation information is used to generate a unique code. In some aspects, orientation information is extracted from an object. The object includes multiple elements, and the orientation information indicates the relative spatial orientations of the respective elements. The orientation information can be extracted, for instance, by a scanner system that detects the elements. A unique code is generated for the object based on the orientation information. In some examples, the elements are diamond particles that each have one or more color centers, and the orientation information is extracted by detecting the color centers.

Generating a unique code from orientation information

In a general aspect, unique unclonable physical identifiers are applied and used. A method of applying the unique marker can include receiving an object having a surface feature and forming a unique marker on the surface feature of the object. The unique marker includes a distribution of elements and conforms with a morphology of the surface feature. The method further includes extracting orientation information from the unique marker. The orientation information can indicate relative spatial orientations of the respective elements. The method additionally includes generating a unique code for the object based on the orientation information. The surface feature can be facets, surface patterns, textures, or other indentations of the object. The surface feature can include a region of the object that is susceptible to tampering.
