Sensing and privacy
Privacy impact assessment
Évaluation des incidences sur la vie privée
Privacy impact assessment is a structured review of how a proposed data activity may affect people’s privacy and what measures can reduce those effects. Curb projects use such assessments to examine purposes, necessity, data flows, access, retention, and alternatives, with formal legal requirements depending on the jurisdiction and processing involved.
Understanding the term
Assessment should occur while design choices can still change. A review after procurement may find risks that are expensive to address because unnecessary collection is embedded in the architecture.
Validate the measurement against an independent reference under representative conditions. Record uncertainty, coverage, missing intervals, and the difference between a raw observation and an inferred activity. Technical outputs should be used only for purposes they can support reliably. Assign responsibility for calibration, corrections, access, and retention, and assess privacy across the complete data flow. An operational dashboard can conceal measurement errors if it displays precise values without their method or limitations.
