World ID is a global digital identity system that is designed to prove that an individual is a real, unique human online.
Developed by Tools for Humanity and forming part of the World blockchain-based identity and financial platform, World ID draws on iris biometrics and other data collected primarily using a chrome orb (aka "The Orb") to create a unique, anonymous identifier.
This unique identifier is linked to an individual's World ID, which can be used online to verify that they are a real person while keeping their personal identity private and enabling them to conduct transactions.
Iris recognition
Iris recognition is an automated method of biometric identification that uses mathematical pattern-recognition techniques on video images of one or both of the irises of an individual's eyes, whose complex patterns are unique, stable, and can be seen from some distance.

World is seen to suffer from several important transparency and accountability limitations:
Limited access to protocol infrastructure, restricting access to independent verification and auditing of the system's operations.
Data usage, retention and deletion policies, including how collected biometric data will be used, stored, and potentially shared.
Governance structure. While the WLD token is intended for potential use in protocol governance, the exact mechanisms and decision-making processes are not fully defined, raising questions about who ultimately controls the project's direction and policies.
Legal and regulatory opacity. Worldcoin has faced regulatory challenges in multiple countries, but has been criticised for it lack of transparency about its plans to address these regulatory concerns and comply with diverse data protection laws.
World ID's governance, field-testing and other activities have prompted concerns about user privacy, security and safety. It has also been accused of misleading and opaque marketing communication, unclear age restrictions, and other issues.
World has been the subject of regulatory investigations, bans and market withdrawals in multiple countries.
