Here's some work I did a couple years ago using some of these principles to fight counterfeit medicines: https://www.nature.com/articles/s41598-022-11234-4 A side note: I think there's an unmet need for algorithms that can convert photos of these random patterns into text (or something similar) that can be stored in a database and searched quickly for matching patterns. I've tried image similarity algorithms like the ones used by e.g. Google Reverse Image Search, but they seem poorly suited for this task. I ended up writing my own crude algorithm in the paper above that converts a pattern into a set of strings, and it works OK, but surely there are better ways to do this.
