In 1967, Justice John Marshall Harlan introduced the litmus test of ‘a reasonable expectation of privacy’ in his concurring opinion in the US Supreme Court case of Katz v. United States. Privacy, regulations to protect privacy, and data protection have been legal and social issues in many Western countries for a number of decades. However, recent measures to combat terrorism, to fight crime, and to increase security, together with the growing social acceptance of privacy-invasive technologies can be considered a serious threat to the fundamental right to privacy. What is the purport of ‘reasonable expectations of privacy’? 
Reasonable expectations of privacy and the reality of data protection is the title of a research project being carried out by TILT, the Tilburg Institute for Law, Technology, and Society at Tilburg University, The Netherlands. The project is aimed at developing an international research network of privacy experts (professionals, academics, policymakers) and to carry out research on the practice, meaning, and legal performance of privacy and data protection in an international perspective.
 
Part of the research project was to analyse the concept of privacy and the reality of data protection in case law, with video surveillance and workplace privacy as two focal points. The eleven country reports regarding case law on video surveillance and workplace privacy are the core of the present book. The conclusions drawn by the editors are intended to trigger and stimulate an international debate on the use and possible drawbacks of the ‘reasonable expectations of privacy’ concept.
