Highly sensitive information about the religious beliefs, political opinions and even the sex life of Britons travelling to the United States is to be made available to US authorities when the European Commission agrees to a new system of checking passengers. The EC is in the final stages of agreeing a new Passenger Name Record system with the US which will allow American officials to access detailed biographical information about passengers entering international airports. Civil liberty groups warn it will have serious consequences for European passengers. In a strongly worded document drawn up in response to the plan that will affect the 4 million-plus Britons who travel to the US every year, the EU parliament said it 'notes with concern that sensitive data (ie personal data revealing racial or ethnic origin, political opinions, religious or philosophical beliefs, trade union membership, and data concerning the health or sex life of individuals) will be made available to the DHS.' The US will be able to hold the records of European passengers for 15 years compared with the current three year limit. The EU parliament said it was concerned the data would lead to 'a significant risk of massive profiling and data mining, which is incompatible with basic European principles and is a practice still under discussion in the US congress.' Peter Hustinx, the European Data Protection Supervisor, has written to the EC expressing his 'grave concern' at the plan, which he describes as 'without legal precedent' and one that puts 'European data protection rights at risk'. Hustinx warns: 'Data on EU citizens will be readily accessible to a broad range of US agencies and there is no limitation to what US authorities are allowed to do with the data.'
