Worldcoin 基金會利用尖端 SMPC 協定升級生物辨識安全

世界幣基金會使用安全多方計算（SMPC）實施了一個新系統，該系統與 TACEO 一起開發，用於生物識別模板保護。這項進步允許安全刪除先前的虹膜代碼系統，從而增強用戶隱私。此舉符合基金會為解決監管機構對資料收集實務提出的擔憂所做的努力。

Worldcoin Foundation Implements Cutting-Edge Biometric Security Protocol

世界幣基金會實施尖端生物辨識安全協議

Introduction

介紹

The Worldcoin Foundation, committed to advancing digital identity verification and financial inclusion, has unveiled a groundbreaking biometric security system that significantly enhances user privacy. This innovative system, utilizing Secure Multi-Party Computation (SMPC), addresses concerns raised by data protection authorities and solidifies the foundation's commitment to ensuring user data security.

世界幣基金會致力於推動數位身分驗證和金融包容性，推出了突破性的生物辨識安全系統，可顯著增強用戶隱私。這個創新系統利用安全多方運算 (SMPC)，解決了資料保護機構提出的問題，並鞏固了基金會對確保用戶資料安全的承諾。

SMPC-Driven Iris Code Encryption

SMPC 驅動的虹膜代碼加密

The centerpiece of the new system is SMPC, a cryptographic technique that allows multiple parties to compute results over encrypted data without revealing the underlying secrets. Worldcoin Foundation has collaborated with cryptography engineers from TACEO to develop an SMPC-based protocol that securely encrypts iris codes into multiple secret shares, distributing them among different parties. These parties then collaborate to perform computations on the encrypted data, verifying the uniqueness of biometric templates without ever accessing the actual secrets, ensuring an unparalleled level of privacy protection.

新系統的核心是 SMPC，這是一種加密技術，允許多方透過加密資料計算結果，而不會洩露底層秘密。世界幣基金會與 TACEO 的密碼學工程師合作開發了一種基於 SMPC 的協議，該協議可以將虹膜代碼安全地加密為多個秘密共享，並將其分發給不同的各方。然後，這些各方協作對加密資料進行計算，驗證生物辨識模板的唯一性，而無需存取實際的秘密，從而確保無與倫比的隱私保護等級。

Proven Efficacy and Extensive Testing

經證實的功效和廣泛的測試

Prior to its implementation, the new SMPC system underwent extensive testing to ensure its reliability and robustness. The Worldcoin Foundation meticulously transferred all existing iris codes to the new system before securely deleting the old data, ensuring a seamless transition without compromising user privacy.

在實施之前，新的 SMPC 系統經過了廣泛的測試，以確保其可靠性和穩健性。世界幣基金會精心地將所有現有虹膜代碼轉移到新系統，然後安全刪除舊數據，確保無縫過渡而不損害用戶隱私。

The system's computational requirements are substantial, demanding 1152 cores, 3.6TB of memory, and 5 Gbps bandwidth across all participating parties. This resource-intensive architecture guarantees the integrity and security of the biometric data.

該系統的運算要求很高，需要 1152 個核心、3.6TB 記憶體以及所有參與者的 5 Gbps 頻寬。這種資源密集型架構保證了生物辨識資料的完整性和安全性。

Regulatory Compliance and Industry Collaboration

監理合規和產業合作

The development of the SMPC system stemmed from discussions with data protection authorities, including the Bavarian Data Protection Authority (BayLDA). Tools for Humanity and Worldcoin Foundation's EU establishment currently participate in the system, with plans to expand participation to additional third parties.

SMPC 系統的發展源自於與資料保護機構（包括巴伐利亞資料保護機構 (BayLDA)）的討論。 Tools for Humanity 和 Worldcoin 基金會的歐盟機構目前參與該系統，並計劃將參與範圍擴大到更多第三方。

This move demonstrates the foundation's commitment to addressing regulatory concerns and adhering to best practices in data privacy and security.

此舉顯示了基金會致力於解決監管問題並遵守資料隱私和安全的最佳實踐。

Enhanced Privacy Measures

加強隱私措施

The SMPC system is part of a broader initiative by the Worldcoin Foundation to enhance user privacy and data security. Other measures introduced in 2024 include:

SMPC 系統是世界幣基金會旨在增強用戶隱私和資料安全性的更廣泛舉措的一部分。 2024 年推出的其他措施包括：

• Personal custody for secure storage of personal information
• User ability to delete iris codes
• On-site age verification to prevent underage sign-ups

These enhancements underscore the foundation's unwavering commitment to user privacy and security.
