Written in blunt, jargon-free prose, On Privacy defines today's privacy landscape while also reminding readers of the joys of keeping things to ourselves: that privacy creates space for intimacy, is essential to mental health, and is a fundamental right in a free society. Explored among the book's twenty brief-but-powerful lessons are concepts like the Nothing-to-Hide Trap, how we become prisoners of our recorded past, and the ways that small data points about us can paint big, revealing pictures. On Privacy is small book with a big message about why privacy matters, who profits by invading it, and how best to defend yours in easy, everyday ways.   160 pages  hc
