'''FLoC''' (short Federated Learning of Cohorts) is a targeted advertising technology developed by [[Google]], for the Chromium browser. It is designed to allow website to perform targeted advertising for anyone who visits their site, but without specifically identifying the individual visitor. When Google released this, they marketed it as a more "privacy-focused" method of targeted advertising, as opposed to using third party trackers.<ref>https://blog.google/products/ads-commerce/2021-01-privacy-sandbox/</ref>

While FLoC is being marketed as a more privacy-focused advertising system (compared to unhindered third party tracking of Chrome users who make not effort to protect their privacy), it has been met with a great deal of opposition. There are a number of main concerns in regard to this new system.
#FLoC runs in the user's browser, doing the hard work of analytics on the user's device, and then broadcasting the results. Not only are the visitor's interests being captured and distributed, but it is being done by the user's own browser, without the user's explicit consent.
#This user data is freely available to every website the browser visits, whether directly (browsing to that site), or indirectly (iframed content, 3rd party scripts, CNAME trackers, etc.)
#Fingerprinting data points
#is 1k really enough?
#3rd party trackers will still track
