The European Union is to impose stricter rules on its own use of private citizens’ data for all future anti-terrorism measures. All future policy proposals must prove that the initiatives are necessary, proportionate and safeguard fundamental rights. Compliance with these rules will be subject to control by an independent authority at national or E.U. level. The new rules will also apply to the Schengen Information System (SIS) and SIS II, through which data are shared on persons moving within the “Schengen Area”, a group of countries which have agreed not to enforce identity checks.”]
