From smartphones to cloud computing, from big data to social media, the exploding use of information technology and its many applications will be a source of massive social and economic changes for years to come. Privacy is one of the areas widely believed to be affected by these changes. Developments such as digital surveillance, electronic profiling, social media, ‘do not track’, privacy-friendly business models, digital records, database interconnection, business intelligence and behavioral marketing have a profound effect on privacy in all its facets.
In the past, privacy has mostly been addressed from a single perspective, for example legal, philosophical, sociological, technical, medical or psychological. At present, however, it is acknowledged that privacy has many facets, and researchers and professionals worldwide are working together to address privacy from a truly interdisciplinary approach.
