Summary
Google's FLoC (federated learning of cohorts) is a proposed alternative to cookie-based user tracking in Chrome that assigns users to interest groups based on their browsing history. The system makes user fingerprinting (identifying individuals by combining their FLoC ID with their IP address) easier and more accurate, potentially compromising privacy even though FLoC IDs are recalculated regularly and Google has disabled it in the European Union due to privacy concerns.
