FLoC (Federated Learning of Cohorts) is a new advertising mechanism created by Google to continue targeted advertising while avoiding the use of third-party cookies due to new data protection regulations in the European Union. FLoC classifies users into groups of thousands and does targeted ads based on the interests of each group, so Google claims it does not violate personal privacy.

However, in reality, it has been criticized by many people, including the Electronic Frontier Foundation, for being able to identify individuals from different types of information.

The Electronic Frontier Foundation points out that the “FLoC” Google plans to introduce is GIGAZINE’s worst
