Yes, this is not statistically well thought out. See Death Note: L, Anonymity & Eluding Entropy (yes it's about a cartoon, but read it for the math). https://gwern.net/death-note-anonymity Also see the 2020 census statistical calculations and the tradeoffs they made. There's "not that many" (compared to the number of ChaCha20 keys, for example) humans in the world, it does not take that many fractional-bit information leaks to get a good read on a person. |
