Identity Proof Minimization
Identity Proof Minimization is the principle of disclosing only the minimum proof or identity information needed for a service decision.
Definition
Identity Proof Minimization is the practice of giving a relying service only the proof strictly required for a business decision rather than full identity documents or excessive personal data. This supports privacy-preserving identity exchanges by reducing over-disclosure while still allowing the verifier to confirm what is necessary.
