Age assurance covers verification, estimation, and hybrid approaches, each with distinct privacy tradeoffs; cryptographic selective disclosure is the most promising privacy-preserving path.
Key Takeaways
Age verification, age estimation, and age assurance are distinct: conflating them leads to mismatched policy and technical choices.
78% of children aged 10-15 held social media accounts despite age limits, because self-reported birthdates are the dominant enforcement mechanism.
Platform-level ID upload, third-party proofing, digital identity wallets, and browser/device-layer checks are the four main architectural options, each with different privacy and interoperability costs.
Zero-knowledge proofs and selective disclosure via verifiable credentials or mobile driver’s licenses could confirm “Age >= 18” without exposing name, address, or ID number.
Centralized age-verification databases are honeypots; data minimization and attribute proofs over identity disclosure should be the default design principles.
