Worldcoin Foundation has introduced a new system using Secure Multi-Party Computation (SMPC) for biometric template protection, developed with cryptography engineers from TACEO.
The advancement has allowed the foundation to securely delete the previous iris code system. The move is part of the foundation’s effort to be more transparent after multiple countries raised concerns over its data collection practices.
Data collection revamp
The new approach, now available open source on GitHub, encrypts iris codes into multiple secret shares distributed among different parties. These parties collaborate to compute results over the encrypted data without accessing the actual secrets, ensuring a high level of privacy for verifying the uniqueness of biometric templates.
Worldcoin Foundation said:
“By migrating to SMPC, we’ve achieved a significant enhancement in privacy protection for our users. After securely transferring all iris codes to the new system, we deleted the old data.”
