Minimal data, maximum privacy. 

Single-attribute verification means confirming just one fact about a user—such as whether they’re over 18 or live in a certain country—without accessing or storing their full identity data. 

With itsme^® Qualify, this is done in a privacy-preserving way using advanced cryptography, so only the necessary facts are shared. This reduces data-handling obligations and supports the future of digital identity: proportional and private. 

Zero-Knowledge Proof (ZKP) is a cryptographic method that allows one party to prove something is true—like a user being over 18—without revealing the underlying personal data. 

itsme^® Qualify uses ZKP to enable single-attribute verification: confirming only the necessary fact while keeping all other identity details private. In other words, ZKP is the technology, and itsme^® Qualify is our solution that applies it in a secure, user-friendly way. 

By design, itsme^® Qualify follows GDPR principles of data minimisation and storage limitation. No eligibility results or personal data are stored after verification — removing retention risks and reducing compliance obligations.

The Digital Services Act introduced stricter obligations for online platforms, especially around the protection of minors and their exposure to harmful content. While use of itsme^® Qualify is not limited to social media or very large online platforms, its design could support companies to meet these requirements. By allowing a simple “yes/no” confirmation of attributes like “18+”, Qualify enables businesses to implement age assurance in a privacy-preserving and proportionate way.  

This approach is consistent with the DSA’s emphasis on user protection and safer digital environments. 

Not necessarily. It complements full KYC by applying only when proportional checks are appropriate, such as gating content or restricting access based on a threshold.

It complements it. Full KYC is necessary in certain contexts, but often excessive for simpler checks. itsme^® Qualification offers a proportional alternative: faster integration, reduced compliance scope, increased user trust, and often, cost-effectiveness.
