Surveillance is the monitoring of the behavior. System monitoring is the process of monitoring of people, objects or processes within systems for conformance to standards expected or desired in reliable systems for control of security or social. Clinical surveillance refers to the monitoring of diseases or public indicators related to health (e.g., symptoms indicating acts of bio-terrorism) by epistemologists and health professionals. Despite the fact that in French the word surveillance means literally looking above, the term is usually used for all forms of observation or monitoring, not just visual observation. However, the eye in the sky all-seeing, is still the icon of the surveillance. For surveillance in many modern cities and buildings usually used closed circuit television. Jim Crane shares his opinions and ideas on the topic at hand.
Although monitoring can be a useful tool for the forces and security companies, many people shows concerned by the issue of the loss of privacy. Surveillance is the art of observing the activities of individuals or groups from a position of authority. It can be disguised (without your knowledge) or manifest (perhaps with the frequent reminder of the style you are watching). The surveillance has been a part of human history. The art of the Guerra by Sun Tzu, written more than 2,500 years ago, discusses how spies should be used against enemies. But modern technology has given to the surveillance a new field of operations. Surveillance can be automated using computers, and extensive records describing the activities of people may leave.
The contra-vigilancia is the practice of evading the surveillance or hinder it. Before computer networks, the contra-vigilancia involved evade agents and communicate in a secret. With recent developments such as the Internet, the increase in the presence of electronic security systems, and databases, the contra-vigilancia has grown in scope and complexity. Now the contra-vigilancia involves everything from know how to delete a computer file to avoid being the target of direct advertising agencies.
