I've not been following this proposal closely I did find https://github.com/WICG/floc https://github.com/WICG/floc >Tracking people via their cohort >A cohort could be used as a user identifier. It may not have enough bits of information to individually identify someone, but in combination with other information (such as an IP address), it might. Whose purpose is: >A FLoC cohort is a short name that is shared by a large number (thousands) of people, derived by the browser from its user’s browsing history. I wonder if it's possible to define a large enough number X that people are OK with the idea. (Cookies are effectively "1" and nothing is "3,010,000,000" ie on the internet) Could the cohort minimum size be configurable? Given the IP address can be known today: what's the existing accidental "FLoC proxy" or "How unique are you online?" Or "online finger print" (something I'd not thought of before: my timezone can significantly narrow down who I am) You can try using yourself on: https://amiunique.org/fp https://amiunique.org/fp
