Control changed

Before · SP 800-63B

Biometric samples collected in the authentication process MAY be used locally within the authenticator or verifier performing the biometric comparison to update the templates for the purpose of compensating for changes in subscriber characteristics or — with explicit subscriber consent — other research purposes. The biometric samples and any other biometric data derived from them SHALL be erased immediately after any adaptation or research data has been derived. A limit on the allowable time for adaptation SHALL be established and enforced by the authenticator or the CSP.
