The Surveillance State

Leading security and privacy researcher Bruce Schneier talks about about the golden age of surveillance and his new book, "Data and Goliath: The Hidden Battles to Collect Your Data and Control Your World." The book chronicles how governments and corporation have built an unprecedented surveillance state. While the leaks of Edward Snowden have shed light on the National Security Agency’s surveillance practices, less attention has been paid to other forms of everyday surveillance — license plate readers, facial recognition software, GPS tracking, cellphone metadata and data mining.
