This paper attempts to study "surveillance" in today's society. Contemporary surveillance is "Dataveillance (data + surveillance)" targeting personal data, not the body, and is practiced by computer programs and artificial intelligences. This fact means that today's surveillance is directed not to "current" but "past" and "future", and the observer is impersonal. Therefore, dataveillance can be expressed as "Eyeless surveillance ", because “gaze” of the dominators is disappeared. Furthermore, today's surveillance society can be defined as a society that we must control our behavior to prevent the risk of becoming a target for surveillance.
