Which of the following is the FIRST step to protect data subject privacy when planning the deployment of a public monitoring system?

Informing the public is an important step but occurs after the PIA has determined what data is collected, what risks exist, and how the public should be notified.

Drafting a breach response plan is a later risk management activity that depends on the risk findings from the PIA being completed first.

A PIA systematically identifies, evaluates, and addresses privacy risks introduced by a new system before it is built or deployed, ensuring privacy is embedded by design. For a public monitoring system, a PIA determines what data is collected, from whom, for what purpose, and what risks exist - informing all subsequent decisions. Completing the PIA first ensures that notifications to the public, authorities, and breach plans are grounded in an accurate understanding of the system's privacy implications.

Notifying data protection authorities may be required as a result of PIA findings but cannot be done accurately before the PIA establishes what the system does and what risks it poses.
