According to a report from The Wall Street Journal, the Federal Trade Commission (FTC) and Google are close to reaching a deal that would force Google to pay a $22.5 million fine for allegedly tracking user behaviors in iOS’ Safari browser. The fine would be the largest in history that the FTC has ever put upon a company in the United States.

The fine is expected to be the largest penalty ever levied on a single company by the U.S. Federal Trade Commission. It offers the latest sign of the FTC’s stepped-up approach to policing online privacy violations, coming just six months after The Wall Street Journal reported on Google’s practices.

Google was accused of placing specific cookies onto users’ devices, which would allow the Internet giant to then track the behavior of the user. The company claimed that the software being placed on certain websites was actually a mistake, and was done merely to use the Google “+1” button on domains other than Google.com.
