Zero knowledge proofs reveal their utility for age verification and beyond: Aztec
The article from Biometric Update, dated May 29, 2025, discusses a research report by Aztec on the potential of zero-knowledge proofs (ZKPs) for privacy-preserving online age verification. The report argues that ZKPs offer a technological solution to age assurance without compromising personal data, contrasting with traditional methods that may infringe on civil liberties and data privacy. ZKPs enable robust identity verification while safeguarding personal information, making them preferable to biometrics-based tools that can sometimes misidentify users. The report highlights the flexibility of ZKPs for both online and offline applications, including gaming and voting, and notes their compliance with privacy regulations like the EU’s GDPR. Examples of services utilizing ZKPs include Anon Aadhaar and OpenPassport, which allow identity verification without revealing private data. The report concludes that adopting ZKPs is crucial for secure, private, and compliant digital interactions.
