Mass surveillance is the intricate surveillance of an entire or a substantial fraction of a population in order to monitor that group of citizens.[1] The surveillance is often carried out by local and federal governments or governmental organizations, but it may also be carried out by corporations (either on behalf of governments or at their own initiative). Depending on each nation's laws and judicial systems, the legality of and the permission required to engage in mass surveillance varies. It is the single most indicative distinguishing trait of totalitarian regimes. It is often distinguished from targeted surveillance.
Mass surveillance has often been cited[by whom?] as necessary to fight terrorism, prevent crime and social unrest, protect national security, and control the population. At the same time, mass surveillance has equally often been criticized for violating privacy rights, limiting civil and political rights and freedoms, and being illegal under some legal or constitutional systems.[2] Another criticism is that increasing mass surveillance could potentially lead to the development of a surveillance state, an electronic police state, or a totalitarian state wherein civil liberties are infringed or political dissent is undermined by COINTELPRO-like programs.[3]
In 2013, the practice of mass surveillance by world governments[4] was called into question after Edward Snowden's 2013 global surveillance disclosure on the practices by the National Security Agency (NSA) of the United States. Reporting based on documents Snowden leaked to various media outlets triggered a debate about civil liberties and the right to privacy in the Digital Age.[5] Mass surveillance is considered a global issue.[6][7][8][9] The Aerospace Corporation of the United States describes a near-future event, the GEOINT Singularity, in which everything on Earth will be monitored at all times, analyzed by artificial intelligence systems, and then redistributed and made available to the general public globally in real time.[10][11]
[...] a Beijing lawyer named Xie Yanyi filed a public information request with the police asking about China's own surveillance operations. [...] 'Most people were critical about the U.S. and supported Snowden.' [he said...] Then the discussion started shifting to take in China's own surveillance issues.
