Computerization has unexpectedly progressed beyond our imagination, from a tool of management and control into one of widespread communication and expression. This book revisits the major questions that have emerged with the progress of computerization over nearly half a century, by describing the context in which these issues were formulated.

By taking a social and digital approach, the author explores controversial issues surrounding the development of this "digital revolution", including freedom and privacy of the individual, social control, surveillance, public security and the economic exploitation of personal data. From students, teachers and researchers engaged in data analysis, to institutional decision-makers and actors in policy or business, all members of today's digital society will take from this book a better understanding of the essential issues of the current "digital revolution".
