As one of Canada's leading innovators and proliferate inventors (holder of 50 patents), Dr. Steve Mann is uniquely posed to survey and study the technologies that exploit anonymity. He is recognized for his pioneering research on wearable computing. He was the first to conceive of the idea, as well as to implement, a voice activated wearable multimedia computer more than 20 years ago. Dr. Mann's wearable computing has profound implications for personal privacy, since it allows the wearer to watch, record and perhaps broadcast his/her surroundings. He has coined the sociological construct known as 'sousveillance' to describe the effect a wearer of his device has on others.
