Knowra Mass surveillance Mass surveillance Mass surveillance is the systematic monitoring of communications or activities across large populations, often using digital technologies and centralized data collection.
Metadata : Data describing other data, such as a message’s sender, recipient, time, or location. Communication metadata can reveal social networks and routines without recording message contents.
Panopticon : An institutional design in which a central observer can watch many people who cannot know when they are observed. Its asymmetry of visibility became a lasting model for thinking about surveillance.
Edward Snowden : A former U.S. intelligence contractor who disclosed classified surveillance documents in 2013. His disclosures exposed the scale and technical reach of U.S. and allied collection programs.
Targeted surveillance : Monitoring directed at specified individuals, accounts, devices, or locations. It narrows collection to identified targets instead of gathering information across a population.
Chilling effect : The deterrence of lawful expression or activity because people fear scrutiny or punishment. Awareness of monitoring can discourage speech, association, and searches for sensitive information.
Bulk data collection : The acquisition of large datasets without selecting each record through individualized suspicion. It captures information about many people at once rather than only named targets.
Census : A systematic count and description of a population, usually conducted by a government. Population-wide information gathering predates electronic surveillance and supplies states with administrative knowledge.
William Binney : A former National Security Agency technical director who became a critic of bulk surveillance. His account of NSA systems and data collection offered an insider’s perspective.
Wiretapping : The interception of telephone or other communications, typically through access to a transmission line or service. A wiretap is commonly tied to a specific line or target, unlike broad population collection.
Privacy law : The body of law governing the collection, use, storage, and disclosure of personal information. Legal protections determine what surveillance data may be collected and how it can be used.
