Surveillance is everywhere today, generating data about our purchasing, political, and personal preferences. Surveillance: A Very Short Introduction (Oxford University Press, 2024) shows how surveillance makes people visible and affects their lives, considers the technologies involved and how it grew to its present size and prevalence, and explores the pressing ethical questions surrounding it.

David Lyon is former Director of the Surveillance Studies Centre and Professor Emeritus of Sociology and Law, Queen's University, Kingston, Ontario.
