Worldcoin 基金会利用尖端 SMPC 协议升级生物识别安全

世界币基金会使用安全多方计算（SMPC）实施了一个新系统，该系统与 TACEO 一起开发，用于生物识别模板保护。这一进步允许安全删除以前的虹膜代码系统，从而增强用户隐私。此举符合基金会为解决监管机构对数据收集实践提出的担忧而做出的努力。

Worldcoin Foundation Implements Cutting-Edge Biometric Security Protocol

世界币基金会实施尖端生物识别安全协议

Introduction

介绍

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.

世界币基金会致力于推进数字身份验证和金融包容性，推出了突破性的生物识别安全系统，可显着增强用户隐私。这一创新系统利用安全多方计算 (SMPC)，解决了数据保护机构提出的问题，并巩固了基金会对确保用户数据安全的承诺。

SMPC-Driven Iris Code Encryption

SMPC 驱动的虹膜代码加密

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.

新系统的核心是 SMPC，这是一种加密技术，允许多方通过加密数据计算结果，而不会泄露底层秘密。世界币基金会与 TACEO 的密码学工程师合作开发了一种基于 SMPC 的协议，该协议可以将虹膜代码安全地加密为多个秘密共享，并将其分发给不同的各方。然后，这些各方协作对加密数据进行计算，验证生物识别模板的唯一性，而无需访问实际的秘密，从而确保无与伦比的隐私保护水平。

Proven Efficacy and Extensive Testing

经证实的功效和广泛的测试

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.

在实施之前，新的 SMPC 系统经过了广泛的测试，以确保其可靠性和稳健性。世界币基金会精心地将所有现有虹膜代码转移到新系统，然后安全删除旧数据，确保无缝过渡而不损害用户隐私。

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.

该系统的计算要求很高，需要 1152 个核心、3.6TB 内存以及所有参与方的 5 Gbps 带宽。这种资源密集型架构保证了生物识别数据的完整性和安全性。

Regulatory Compliance and Industry Collaboration

监管合规和行业合作

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 系统的开发源于与数据保护机构（包括巴伐利亚数据保护机构 (BayLDA)）的讨论。 Tools for Humanity 和 Worldcoin 基金会的欧盟机构目前参与该系统，并计划将参与范围扩大到更多第三方。

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

此举表明了基金会致力于解决监管问题并遵守数据隐私和安全方面的最佳实践。

Enhanced Privacy Measures
