Opinion - How zero-knowledge tools can help us verify age and protect privacy online
The article explains how zero‑knowledge cryptographic tools let individuals prove a fact—like being over 18—without revealing underlying details such as date of birth or identity. A person can prove age without disclosing anything else. These tools are increasingly important in digital ID and privacy-preserving applications. Companies like Google, in partnership with European institutions such as Sparkasse, have open‑sourced zero‑knowledge libraries to make implementing privacy‑enhancing systems more accessible. The article argues that broader adoption of these tools could transform age verification, digital identity and online privacy practices.
