Facebook has unveiled a comprehensive series of privacy enhancements designed to extend protections required by Europe’s GDPR to all of the social media company’s users around the world. The updates, which include major changes to the company’s terms and data policies, fulfill promises CEO Mark Zuckerberg made to House and Senate members in Washington D.C., Facebook officials said. The congressional grilling followed disclosures that Facebook had allowed political data firm Cambridge Analytica to gain unauthorized access to user data.
