A privacy-focused technology introduced by Google as part of its efforts to replace third-party cookies in web browsers. It aims to provide advertisers with a way to deliver targeted ads while preserving user privacy. FLoC groups users into cohorts based on their browsing habits and interests. Instead of tracking individual users, FLoC assigns users to these anonymous cohorts. Advertisers can then target their ads at these cohorts rather than specific individuals, which is intended to be more privacy-friendly.
How FLoC Works
FLoC works within the web browser itself. The browser generates the cohorts locally without sharing individual user data with websites or advertisers. This approach is seen as a response to growing concerns about online privacy and the tracking of users' online activities.
Privacy Implications
- Anonymous cohorts: FLoC assigns users to anonymous cohorts based on browsing habits and interests, rather than tracking individual users.
- Local processing: The browser generates the cohorts locally, ensuring that individual user data is not shared with websites or advertisers.
Alternatives and Context
