Mass surveillance is the systematic monitoring, collection, and analysis of personal data by state and non-state entities.
The data generated by devices, applications, and platforms has given rise to new forms of mass surveillance, such as biometric surveillance, mobile network monitoring, advertising intelligence (ADINT), and automated pattern recognition systems.
New technologies, artificial intelligence, and commercial data brokers have transformed surveillance capabilities, enabling governments and corporations to capture, process, and analyze unprecedented volumes of personal information, often without an individual’s knowledge or consent. These mass surveillance opportunities pose serious threats to human rights and civil society.
We analyze both the technological infrastructure that makes mass surveillance possible and the evolving regulatory and legal frameworks that govern these practices.
