(YAHOO NEWS) -- The post office’s law enforcement arm has faced intense congressional scrutiny in recent weeks over its Internet Covert Operations Program (iCOP), which tracks social media posts of Americans and shares that information with other law enforcement agencies. Yet the program is much broader in scope than previously known and includes analysts who assume fake identities online, use sophisticated intelligence tools and employ facial recognition software, according to interviews and documents reviewed by Yahoo News.
Among the tools used by the analysts is Clearview AI, a facial recognition software that scrapes images off public websites, a practice that has raised the ire of privacy advocates. The U.S. Postal Inspection Service uses Clearview’s facial recognition database of over 3 billion images from arrest photos collected from across social media “to help identify unknown targets in an investigation or locate additional social media accounts for known individuals,” according to materials reviewed by Yahoo News.
