Sousveillance is a term first coined by wearable computing pioneer Steve Mann to describe inverse surveillance. THe term comes from the French "sous" (from below) and "viller" (to watch). To Watch from Below. Portable recording devices have given the general public the capability to perform sousveillant acts. To surveill as opposed to be surveilled. A citizen taking a mobile phone video in order to show evidence of a crime is an example of Sousveillance.
Mann calls the systems of Sousveillance and Surveillance self-balencing, pointing out that societies may employ Sousveillance "as a way to balance the increasing (and increasingly one-sided) surveillance."
