About this paper
Wojciech Wodo, Maksymilian Gorski, Lucjan Hanzlik
Wodo, Gorski, and Hanzlik address the inadequacy of current web age verification methods for restricted content, which are often bypassed and lack privacy. They propose an anonymous age verification framework utilizing open standards like Privacy Pass and Apple Private Access Tokens, offering cryptographic guarantees for user privacy and unlinkability while enhancing security and usability without requiring specialized software.
Key insights
- The fundamental flaw in current age verification lies in accepting diverse methods with varying and often low levels of assurance, creating easily exploitable weak links.
- Leveraging established open cryptographic standards (e.g., Privacy Pass, blind signatures) allows for the construction of a robust, privacy-preserving age verification system without necessitating new, complex infrastructure.
- A diversified ecosystem of Attesters and Issuers (including qualified Trust Service Providers) can enhance scalability, resilience, and user trust, contrasting with over-reliance on a single, potentially distrusted governmental solution.
