Has the demand for and use of electronic surveillance increased? The rapid changes in telecommunications technology has been accompanied by a growth in the potential intrusiveness of electronic surveillance and a steady increase in government surveillance activity. Surveillance is the monitoring of behavior of people, objects or processes within systems for conformity to expected or desired norms. Although the word surveillance literally means "watching over" the term is often used for all forms of observation or monitoring, not just visual observation. Such as the art of watching over the activities of persons or groups from a position of higher authority. Surveillance may be covert (without a persons knowledge) or overt (perhaps with frequent reminders such as "we are watching over you"). Because they're continually making new discoveries to increase the effectiveness of biometrics, rfid chips, etc., the government may soon be tracking us all.
The next ten years will bring major advancements in the field of biometrics -- things like reading faces, fingerprints and irises to safeguard our own security and personal information.
