- Dma54rhs 4y agoYou can just share a document with small differences to suspected moles. You don't jsv to even change the text, typo or comma here and there sufficient. Football (soccer) coaches have used the tactic to identify who from their own team leaks stuff to the press etc, it's s very old tactic.
- munificent 4y agoThe technique is called a "canary trap" or "barium meal test": https://en.wikipedia.org/wiki/Canary_trap https://en.wikipedia.org/wiki/Canary_trap No idea if anyone offers it as a service. It's unlikely because the primary consumer of the service would be someone trying to prevent documents from leaking, so trusting them to the service is itself a major point of failure.
- xeromal 4y agoI don't know any services, but I do remember years ago that someone was stealing Google's map data so they left a mistake in their map and sued the thieving company with proof in their mistake being in the thief's mapping system. It might not have been Google, but hopefully someone can chime in and remind me. lol
- jdougan 4y agoAs I understand it, that is a traditional thing for map publishers to do.
