Data minimization techniques in credential design include issuing selective disclosures, where users share only necessary attributes (e.g., "over 18" instead of birthdate). Zero-knowledge proofs enable verification without revealing raw data. Credentials are structured as modular, context-specific claims (e.g., "licensed driver" vs. full driving record). Decentralized storage limits data retention, while expiration dates and revocation registries ensure obsolete credentials are purged, aligning with GDPR’s "privacy by design" principles.
