What is Surveillance?
The monitoring of behavior, activities, or information for the purpose of influence, management, or control. Surveillance can be government (law enforcement, intelligence), corporate (advertising, data brokers), or interpersonal (stalking, domestic abuse).
Also known as: Monitoring, Watching, Observation
Surveillance is observation with power. Someone watches, records, or analyzes—and that knowledge can be used to influence, control, or harm.
Types of Surveillance
Government Surveillance
- Law enforcement: Warrants, wiretaps, subpoenas
- Intelligence: Bulk collection, signals intelligence, metadata analysis
- Border and travel: Device searches, biometrics, watchlists

Corporate Surveillance

Surveillance and Power
- Asymmetric: Watchers have power over the watched
- Chilling effect: Knowledge of surveillance changes behavior
- Normalization: Constant surveillance makes it seem acceptable

Metadata Surveillance
You don't need to read the content. Metadata—who, when, where, how long—often reveals more than the message itself. Mass metadata collection is a form of surveillance that bypasses content encryption.
Related Terms
Mass Surveillance
The systematic monitoring of entire populations' communications, movements, and activities by governments, enabled by modern technology and justified as necessary for national security.
Metadata
Data about data. In the context of communications, metadata includes information like who you contacted, when, for how long, and from where—everything except the actual content of your message. Metadata can reveal intimate details about your life even when content is encrypted.
Privacy
The right to control access to your personal information and to be free from unwanted observation or surveillance. Privacy is not about having something to hide—it's about autonomy, dignity, and the ability to choose what you share and with whom.
