A breach of a government database can expose data that is particularly difficult to remediate because official records are harder to dispute or correct than commercial accounts.
New Hampshire residents are protected by N.H. RSA § 359-C:20, which gives you the right to pursue legal remedies when a company fails to adequately protect your data.
