Require that consent or comparable legal basis be sought consistently for all collections of sensitive human subject data and metadata, including personal data, and that any use be in conformity with the consent granted, applicable privacy regulations, and ethical principles.
Where it is proposed that personal data be used in ways not initially foreseen in the consent granted and seeking consent for such new use is impractical, specific case-by-case arbitration implemented by ethics review boards or similar authorities may be appropriate.
Such case-by-case arbitration should also be accompanied by a review taking into account legal aspects of the planned change of purpose.
