Global Age Verification Sparks Privacy and Security Risks
From the UK’s chaotic age-gate enforcement to US states’ new ID mandates and the EU’s digital ID trials, online age verification has become a privacy and security minefield. Third-party checks expose sensitive data to breaches, while digital IDs and zero-knowledge proofs promise safer alternatives. Policymakers must balance child safety with user privacy as global regulations evolve.
Rolling Out Age Verification: A Global Experiment
On July 25, the UK began enforcing age verification under its Online Safety Act, mandating that sites with “harmful” content confirm users are over 18. Early results have been chaotic, with some platforms withdrawing from the market and others facing user workarounds like VPNs and fake IDs.
Verification methods vary widely, typically asking for one of the following:
- Enter a payment card
- Upload a government-issued ID
- Take a selfie for biometric matching
- Allow platforms to estimate age using account data
Most services outsource these checks to third parties like Persona, k-ID, or AU10TIX, resulting in a patchwork of privacy policies and retention schedules. Without standardization, user data faces varied deletion guarantees and security protocols.
Last year, a researcher discovered that AU10TIX exposed driver’s license photos and personal data for months, highlighting how common breaches can endanger sensitive information collected for age verification.
Standardizing Digital IDs and Zero-Knowledge Proofs
To address fragmentation, the EU is piloting a centralized digital ID system. Users upload their passport or ID into a government-managed platform, which issues a “proof of age” token for sites to verify without retaining raw documents.
Zero-knowledge proofs (ZKP) promise further privacy by confirming age without revealing birthdates. Google Wallet’s open-source ZKP module is already influencing EU trials of this cryptographic approach.
Meanwhile, US states from Alabama to Texas have enacted age-gating laws for adult sites, and Australia is experimenting with search engine filters. Yet legal battles in several states show that broad social media or app store mandates remain stalled.
As governments push for child safety online, organizations must adopt solutions that balance compliance, privacy, and user trust. Preparing for diverse verification methods and emerging technologies will be critical in navigating this evolving landscape.
