Origin: [F., fr. surveiller to watch over; sur over + veiller to watch, L. vigilare. See Sur-, and Vigil.]
Surveillance is the monitoring of the behavior, activities, or other changing information, usually of people for the purpose of influencing, managing, directing, or protecting. Surveillance can be the observation of individuals or groups by government organizations but can also relate to disease surveillance, which monitors the progress of a disease in a community while not directly observing individuals. The word surveillance is the French word for "watching over"; "sur" means "from above" and "veiller" means "to watch". The inverse of surveillance is sousveillance. The word surveillance may be applied to observation from a distance by means of electronic equipment, or interception of electronically transmitted information. It may also refer to simple, relatively no- or low-technology methods such as human intelligence agents and postal interception. Surveillance is very useful to governments and law enforcement to maintain social control, recognize and monitor threats, and prevent/investigate criminal activity. With the advent of programs such as the Total Information Awareness program and ADVISE, technologies such as high speed surveillance computers and biometrics software, and laws such as the Communications Assistance For Law Enforcement Act, governments now possess an unprecedented ability to monitor the activities of their subjects.
