The accelerating demand for greater security drives much surveillance. This is obvious in, say, an airport, but it is also visible in policing and even in workplace monitoring. It is not clear, however, that such surveillance makes us safer.

It is more difficult to decide what information is private and what is not. Your name or social insurance number clearly identify you as an individual, but what about a group photo in which you appear that is later posted on Facebook or a picture taken by a traffic camera of your car licence plate number? Each can be used to identify or track you.

Surveillance practices and processes are becoming globalized. Canada is far from unique in experiencing rapid surveillance growth. In fact, much surveillance originates in broader international policy changes. Airlines, for example, operate with similar routines worldwide. How we deal with this depends on specifically Canadian traditions, laws, and cultures.

The human body is increasingly a source of surveillance. Fingerprinting, iris scanning, facial recognition, and DNA records are now commonly used to identify individuals. Our bodies become passwords, and delicate tracings of our body are sometimes seen as more reliable than our statements and stories.
