A German data watchdog has been investigating OpenAI CEO Sam Altman's Worldcoin project since late last year due to concerns over its large-scale processing of sensitive biometric data, the regulator's president told Reuters. The Bavarian State Office for Data Protection Supervision started investigating Worldcoin in November 2022 because of concerns that the project seeks to process "sensitive data at a very large scale" using new technology, Michael Will, the state regulator's president, told Reuters in emailed comments on Friday. Will said the Bavarian state regulator is the lead authority investigating Worldcoin under the European Union's data protection rules because Tools For Humanity, the company behind Worldcoin, has a German subsidiary there.
