When I read the title, I honestly thought this was about some kind of algorithm I wasn't aware of (cf. red-black trees).

I suppose zebras are basically walking barcodes :)

Not entirely the same thing, but I feel like a link to the legendary Banana Sticker Museum is in order here: http://bananen-aufkleber-museum.de/

You’d be better off never looking at the Holotypic Occlupanid Research Group website.

What about their privacy though?

It is a joke, but it makes you think why we think animal privacy is not a real thing whereas if you’d do this with people you’d have a whole lot of criticism. Very rightly so I might add.

Every bovine in the EU is subject to tracking as an anti-disease measure: https://en.wikipedia.org/wiki/British_Cattle_Movement_Servic... et al.

They use traditional ear tags, but you can also get RFID ear tags, and I once met someone who was working on iris recognition for cows.

Our human race is generallyso cruel to animals when farming them that animal privacy is too small a problem to care about.

Now if privacy would be location of animals given to hunters, that I would see as a big problem.
