For nine years he was Chief Privacy Adviser for Microsoft Europe, and four years director of the think-tank the Foundation for Information Policy Research (www.fipr.org). He was an expert adviser to the UK Parliament on privacy and surveillance legislation, and co-organized six public conferences on encryption, data retention, and interception policy.

Mr. Bowden has written a report for the European Union, warning of the dangers of storing personal information on cloud services due to the possibility that US authorities could intercept all the information. He writes that the US Foreign Intelligence Surveillance Act Amendment Act (FISAAA) allows US authorities to access private cloud data.
