Quotes that support claims

The PBH launch comes several months after World unveiled the Secure Multi-Party Computation (SMPC), a cryptographic breakthrough enabled the perfect secrecy of personal information and the deletion of old iris codes. The SMPC ensures that all information used to verify a person’s World ID is not only encrypted but also split into multiple secret fragments distributed to trusted parties, making it impossible to link anonymized data back to an individual.
