A public authority runs citywide ANPR that stores all vehicle movements indefinitely. What compliance theme is most important?
Select an answer to reveal the explanation.
Short Explanation
Tracking every car forever is a panopticon with license plates. Even public bodies need a clear legal basis, a real need, and retention limits. “Smart city” is not a blank cheque.
Full Explanation
Automatic number-plate recognition can constitute personal-data processing when plates link to identifiable individuals. Public-authority surveillance must be grounded in clear law, pursue legitimate aims, and respect necessity, proportionality, purpose limitation, and storage limitation. Indefinite retention of all movements citywide is difficult to reconcile with those constraints without tightly defined purposes and safeguards.
