Spain's AEPD data protection agency has temporarily suspended the activities of Worldcoin, a cryptocurrency project by Sam Altman that uses biometric data collection, specifically eye scans, to verify users' identities. The suspension, lasting three months, is part of a broader investigation into the project's compliance with data protection laws. Worldcoin has been given a 72-hour deadline to halt data collection and processing and to ensure that previously collected data is not used. The company has announced its intention to file a legal challenge against Spain's temporary ban.
