Processing for archiving in the public interest, scientific or historical research or statistics must respect minimisation and use anonymisation or pseudonymisation whenever the purpose can be achieved that way; access, rectification, restriction and objection may be limited only as far as they would make the purpose impossible or seriously impair it; public-interest archives follow Decree-Law 16/93; consent for research may cover several areas or specific projects but must respect recognised scientific ethics; statistical data must be anonymised or pseudonymised so that re-identification is impossible once the operation ends.
