"Profiling the European Citizen" is a specialized book that addresses the challenges of the information society. In an era where the amount of available information is growing exponentially, the ability to select and interpret relevant information is becoming increasingly important. This book examines the role of profiling technologies as a potential solution for structuring and organizing the flood of data. It provides a comprehensive analysis of what profiling is, where it is applied, and what impact it can have on democracy and the rule of law. The content is based on extensive research conducted within the FIDIS (Future of Identity in the Information Society) network and offers a multifaceted perspective on the topic. The editors, Mireille Hildebrandt and Serge Gutwirth, contribute their expertise to illuminate the complex relationships between identity, information, and society.
