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.
Claims21
A method for generating a unique code for an object, the method comprising:
- receiving an object comprising elements, wherein the elements are flakes or foils, and each element has an external structure that defines an orientation of the element;
- extracting orientation information from the object, the orientation information indicating relative spatial orientations of the respective elements with respect to one another, the orientation information being extracted by a scanner system detecting the elements;
- and
- generating a unique code for the object based on the orientation information.
A scanner system comprising:
- a sample region configured to receive an object comprising elements, wherein the elements are flakes or foils, and each element has an external structure that defines an orientation of the element;
- a probe configured to extract orientation information from the object by detecting the elements, the orientation information indicating relative spatial orientations of the respective elements with respect to one another;
- and
- a processor configured to generate a unique code for the object based on the orientation information.
A method for generating a unique code for an object, the method comprising:
- obtaining orientation information extracted from an object, the orientation information indicating relative spatial orientations of respective elements of the object with respect to one another, wherein the elements are flakes or foils, and each element has an external structure that defines an orientation of the element;
- and
- by operation of one or more processors, generating a unique code for the object from the orientation information.
