An anonymous reader writes "U.S. law enforcement and intelligence services can use the PATRIOT Act/FISA to 'obtain' EU-stored data for snooping, mining and analysis, despite strong EU data and privacy laws, according to a recent research paper. One of the paper's authors, Axel Arnbak, said, 'Most cloud providers, and certainly the market leaders, fall within the U.S. jurisdiction either because they are U.S. companies or conduct systematic business in the U.S. In particular, the Foreign Intelligence Surveillance Amendments (FISA) Act makes it easy for U.S. authorities to circumvent local government institutions and mandate direct and easy access to cloud data belonging to non-Americans living outside the U.S., with little or no transparency obligations for such practices -- not even the number of actual requests.' Arnback added, 'These laws, including the Patriot Act, apply as soon as a cloud service conducts systematic business in the United States. It's a widely held misconception that data actually has to be stored on servers physically located in the U.S.'"
