Biometric Surveillance

Privacy

Use of biometric identifiers at scale for identification, verification, or tracking across contexts.

Definition

Biometric surveillance deploys systems (cameras, sensors) to capture biometric signals and match them against databases or templates. Risks include false positives, chilling effects, and cross-context tracking.

In plain English Use of biometric identifiers at scale for identification, verification, or tracking across contexts.

Why this matters

Why it matters: Biometric identifiers are persistent; misuse or breaches can have long-term privacy consequences and can enable mass tracking without meaningful consent.

Example

Example: A city deploys facial recognition on CCTV; governance requires strict lawful basis, audits, transparency, and opt-out mechanisms where possible.
