Report on the balance between security and privacy after 11 September 2001, commissioned by the European Parliament, the committee on Citizens' Freedoms and Rights, Justice and Home Affairs (LIBE). The study analyses the security and privacy implications of three emerging technologies: identity management (on-line services based on the identification of the user), location-based services (focusing on local positioning and tracking of the user) and virtual residence in an ambient intelligence environment (with smart and mobile electronic devices connected to our home, office, car etc.). According to the report, there is a need to restore the balance in favour of privacy as the use of these technologies for some governmental or commercial actions stretch the ability of current legislation to provide adequate personal data protection.
