... EU citizens' data stored on US servers is not protected from access by a third party.
According to a report commissioned by the EU and carried out by the Centre for European Policy Studies, America's so-called Patriot Act gives US authorities the legal right to access foreign citizens' data stored within US borders.
Commenting on the report, European Parliament member Jan Philipp Albrecht insists that "this study is absolutely not about generating panic."
According to Mr Albrecht, most users don't even know where their data is stored.
"It's a simple fact that the US data protection law only applies to US citizens." "But there are special laws that target the surveillance of non-US citizens", he added.
"This happens when sensitive data from big companies, like Microsoft, Amazon, Twitter and Facebook, are made available to US authorities for investigations."
Thilo Weichert, data protection commissioner for the northern German state of Schleswig-Holstein is also concerned at the power wielded by the US over EU citizens' data.
Mr Weichert has been following the implications of this development closely for more than two years, while pushing Facebook to allow its users to remain anonymous.
"The long arm of US law stretches as far as Europe," he said.
