Facebook’s India policy head Ankhi Das and its managing director for India Ajit Mohan on Friday appeared before a Parliament panel on the issue of data security. The Facebook India representatives were asked some tough and searching questions by the members of the panel, sources said. Sources say Ankhi Das, Facebook’s policy head, was questioned on data protection. Facebook was told that it cannot use the personal data of citizens for “inferential” purposes in advertising or business or elections. MPs across parties reportedly asked specific questions on what percentage of Facebook’s revenue is spent on safeguards for data protection. The joint parliamentary committee has called Facebook, Twitter and Amazon to discuss data protection and privacy as it looks into the Personal Data Protection Bill, 2019 following concerns raised by opposition parties.
