Mass surveillance refers to the extensive monitoring of individuals or groups, often conducted by governments or organizations. This practice typically involves the collection of data through various means, such as cameras, internet tracking, and phone tapping. The goal is to gather information for security, law enforcement, or social control purposes. The rise of technology has made mass surveillance more prevalent, with tools like facial recognition and big data analytics enabling the analysis of vast amounts of information. While proponents argue it enhances safety, critics raise concerns about privacy violations and the potential for abuse of power.
