Abstract
The disclosure features dendritic tags, and methods and systems for fabricating and using such tags. The methods can include obtaining at least one image of a dendritic tag attached to an article, analyzing the at least one image to identify a set of features associated with the dendritic tag, and comparing the set of features to stored information to identify the article.
Claims20
A method, comprising:
- obtaining at least one image of a dendritic tag attached to an article, wherein the dendritic tag comprises a dendritic structure comprising a plurality of members extending away from a common point of the dendritic structure to form a stochastically branched arrangement of the members;
- analyzing the at least one image to identify a set of features associated with the dendritic tag;
- and
- comparing the set of features to stored information to identify the article.

A system, comprising:
- an illumination source configured to direct incident light to a dendritic structure in a tag attached to an article or to a container comprising the article, wherein the dendritic structure comprises a plurality of members extending away from a common point of the dendritic structure to form a stochastically branched arrangement of the members;
- a detector configured to obtain an image by measuring incident light reflected from the dendritic structure;
- and
- at least one electronic processor configured to:
- analyze the image to identify a set of features associated with the dendritic structure, wherein the set of features comprises an origin of the dendritic structure, branch points of the dendritic structure, and termination points of branches of the dendritic structure;
- and
- compare the set of features to reference information for a plurality of dendritic structures to determine information about the article.
