Abstract
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.
Claims22
1-129. (canceled)
An authentication marker, comprising:
- a suspension medium;
- and
- elements suspended in the suspension medium, wherein the elements define a distribution of element properties that is detectable by a scanner system and forms a unique identifier of the authentication marker, and the elements comprise:
- a first subset of elements;
- and
- a second subset of elements that is distinguishable, by the scanner system, from the first subset of elements.
A method, comprising:
- receiving an authentication marker comprising elements in a suspension medium;
- and
- by operation of a scanner system:
- identifying a first subset of the elements,
- identifying a second subset of the elements, wherein the first and second subsets of the elements are distinguishable by the scanner system, and
- determining a unique identifier of the authentication marker based on at least one of the first and second subsets of the elements.
