If the investigation results in a determination that there has been a breach in the security system, the person shall notify the individuals affected. The notice shall be made in the most expedient manner possible and without unreasonable delay subject to the needs of law enforcement as provided in subsection C of this section and any measures necessary to determine the nature and scope of the breach, to identify the individuals affected or to restore the reasonable integrity of the data system.

Cooperation shall include sharing information relevant to the breach of the security of the system with the owner or licensee. The person that owns or licenses the computerized data shall provide notice to the individual pursuant to this section. The person that maintained the data under an agreement with the owner or licensee is not required to provide notice to the individual pursuant to this section unless the agreement stipulates otherwise.
C. The notification required by subsection A of this section may be delayed if a law enforcement agency advises the person that the notification will impede a criminal investigation. The person shall make the notification after the law enforcement agency determines that it will not compromise the investigation.

1. Written notice.
