Surveillance is the act of watching someone. When people know that they are being watch they tend to alter their behavior. According to the lecture “We change our behavior based on who is watching us. For example if your parents or spouse are watching you, you behave differently than if your friends are watching.” Which makes surveillance a source of power. Since the person doing the surveillance obtains the sense of power over the person. According to the lecture “When we look, we are in charge. When we are looked at, we are not in charge.” Surveillance allows institutions and major companies to have social control over individuals. For example in the article “Foucault’s Panopticon” Foucault stated, ” That power should be visible and unverifiable. Visible: the inmate will constantly have before his eyes the tall outline of the central tower from which he is spied upon. Unverifiable: the inmate must never know whether he is being looked at any moment; but he must be sure that he may always be so.” So the subject should know they are being watch but not know when he’s being watch. Since the person doing the surveillance can lose his power if the individual becomes comfortable. While this ideas are brought up by Foucault their are other researchers who can agree with him. According to the article “Surveillance, Power, and Everyday Life” Lyon stated, “ICTs are utilized to increase the power, reach and capacity of surveillance systems. The specific kind of surveillance discussed here is perhaps the fastest growing and almost certainly the most controversial, namely the processing of personal data for the purposes of care or control, to influence or manage persons and populations.” Which shows how power is use on daily basis.
