Laurie Taylor talks to Becca Voelcker, Lecturer in the Art Department at Goldsmiths, University of London, about her research into the relationship between sight and power. Everyday life is full of moments where we are seen, often without our knowledge, even in the virtual world, where cookie trails and analytics make us visible to profit making companies. Going back in time, Jeremy Bentham's panopticon depended on seeing its occupants to control them. If we cannot control who sees us today are we also being controlled? How does that square with the many moments when being seen is also a means of social recognition?Also, David Lyon, Professor Emeritus of Sociology and Law at Queen's University, Kingston, Ontario explores the surveillance which permeates all aspects of our lives today. Every click on the keyboard, every contact with a doctor or the police, each time we walk under a video camera or pass through a security check we are identified, traced, and tracked. So how does surveillance make people visible, how did it grow to its present size and prevalence, and what are the social and personal costs?Producer: Jayne Egerton
