Worldcoin Foundation and the TACEO cryptographic engineering team have applied the latest advances in Secure Multi-Party Computation (SMPC) to improve privacy protection and uniqueness of iris codes. Here are the key points about this new system:
Secure Multi-Party Computer (SMPC)
- SMPC and Iris Code: SMPC allows the iris code to be separately encrypted into many different secret parts, each held by a different party. These parties can then calculate results on the encrypted information without having to reveal any confidential information.
- Privacy Protection: The SMPC system helps protect user privacy by ensuring that none of the participating parties can fully access the iris code.
Uniqueness Guaranteed
- Uniqueness Verification: With SMPC, Worldcoin can verify the uniqueness of biometric samples (iris code) without revealing the actual information. This helps prevent the creation of multiple fake identities or identity duplication.
- Delete Old System: After migrating iris codes to the new SMPC system, the previous uniqueness checking system will be securely deleted, ensuring that old data no longer exists and cannot be accessed. abused.
Benefits of the New System
1. Optimal Privacy: The SMPC system ensures that users' biometric data is maximally protected, reducing the risk of personal information leakage.
2. Trusted Verification: The new system allows the uniqueness of iris codes to be accurately and securely verified, helping to maintain the integrity of the identification system.
3. Safe Migration: Data conversion to the new SMPC system and deletion of the old system are done safely, minimizing security risks.
đ Conclusion
Worldcoin Foundation and TACEO are pioneering the application of SMPC advances in the field of biometrics, especially iris coding. The new system not only enhances privacy protection but also ensures the uniqueness of biometric templates, creating a secure and trustworthy identification platform. Migrating iris codes to the SMPC system and safely deleting the old system is a testament to their commitment to protecting user information and improving the reliability of biometric recognition services. .
