Who must be told, and when
Disclosure to an affected resident is due in the most expedient time possible but not later than forty-five days following discovery or notification of the breach in the security of the system.
Section 1349.19 as served contains no requirement to notify the Attorney General or any other regulator. The Attorney General appears instead as the enforcer, who may investigate and bring a civil action. That split is worth noticing: in Ohio, the state's role begins after an incident, not with a filing.
