This guy's lab does some really cool stuff using really basic ideas: - https://groverlab.org/research/2022-05-06-candycodes.html - https://groverlab.org/research/2026-03-19-disintegration-fin... (edit: Formatting)

This was a fun experiment but dang the formatting of this post was so hard to read.

It's baffling that the counterfeiters don't use the exact same design for the box. At least using the same text. Almost seems harder to make text thats sort of close but not just a straight copy.

This was not quite the way I expected to use AI

Replacement laptop batteries and power adapters have a huge problem with counterfeiting as well. In most cases it's a lot easier to spot because e.g. they rearrange the logos. Even if these techniques did not produce false positives on genuine products, I suspect that they would not scale well. If counterfeiters realized they were losing a lot of sales through AI detection, they will just use AI to catch the errors themselves.

This is genius - I’ve had good look using AI to identify fakes (or just reproductions) in other areas. It’s surprisingly good, and works fast enough to be usable in a fast paced live auction environment.

The candycodes mentioned at the end of the article are absolutely brilliant as well. These products have extremely intimate relations with bodies and protecting that chain can avoid a lot of harm.

> In conclusion, I’m pretty negative about AI in general, but this experience made me cautiously optimistic about the role the technology could play in protecting consumers from counterfeit products. Whaaaattt? How could the author go through such detail and discover that Gemini completely failed in the assigned task (calling all the products fakes when some were and some weren't means that it provided zero correct assistance in this discrimination task) and then conclude "AI could play a helpful role"??? Does the author also conclude that stopped clocks could play a helpful role telling time because the are correct twice a day? Apparently AI isn't the only thing that hallucinates.

Thanks, this is how we should use AI, not creating useless slop in a hope to get karma and stars.

Last week, my wife who grew up in a hilltribe away from the modern world was using Gemini for this exactly. She found out that some face cream she bought was fake. I've been working with AI for the last 8 years. I didn't want to pollute her mind with AI and tech because I love the way she walks around thinking about fruit and trees and nature but she learned how to use AI by herself. She uses it for learning how to do things in "the city" like booking airplanes and hotels and asks Gemini questions all the time.

Counterfeit makers are also going to start using AI to find problems and improve their offering.
