PRIVACY-3. ATTRIBUTE MINIMIZATION

Entities requesting attributes MUST evaluate the need to collect specific attributes in a transaction, as opposed to claims regarding those attributes. Wherever feasible, entities MUST collect, generate, use, transmit, and store claims about USERS rather than attributes. Wherever feasible, attributes MUST be transmitted as claims, and transmitted credentials and identities MUST be bound to claims instead of actual attribute values.

SUPPLEMENTAL GUIDANCE

Where feasible, Identity Providers (and any other entities releasing attributes) should provide the opportunity for attributes to be released as claims as well as detailed attributes; see also PRIVACY-1 (DATA MINIMIZATION) on granularity of requests to support data minimization by requesters, generally.

Attribute providers may be required by their own business processes to collect and store, although not necessarily transmit, attributes in their attribute form, in which case significant alteration or filtering may be required when that data is re-used or transmitted to others.
