Is anyone working on use of PUFs and blockchain to verify the origin of physical objects? Specifically use of craquelure or optical PUFs. Thank you.

I heard of someone… somewhere who was using a splatter of UV in, that can only be seen by a certain lenses of some sort to create a unique pattern.
the only problem is if that ink is permanent or could fade away and or change the pattern.
It definitely something that many people are NOT considering.
