Direct answer
What is New Hampshire's data breach notification law?
New Hampshire's breach notification law (N.H. Rev. Stat. sect. 359-C:19 et seq.) requires businesses to notify affected residents as quickly as possible after determining that notification is required after a breach of personal information. New Hampshire requires businesses to notify affected residents and the Attorney General of breaches of unencrypted personal information without unreasonable delay, once misuse becomes reasonably likely.
