Data Breach Notice to Residents and State Authorities in Idaho

Short answer An Idaho business that owns or licenses covered computerized data must promptly investigate a breach and notify affected residents as soon as possible if misuse occurred or is reasonably likely. A nonowner holder must promptly tell and cooperate with the owner or licensee when that misuse condition is met. The general private-entity breach provisions do not require a separate Attorney General or consumer-reporting-agency filing.

Requirements one by one

Covered information and misuse investigation

Idaho Code § 28-51-104(2),(5) defines a breach as illegal acquisition of unencrypted computerized personal information that materially compromises its security, confidentiality, or integrity. Covered information is a resident's name with a Social Security number, driver's license or Idaho ID number, or financial-account access data. Lawfully public government or widely distributed media information is excluded. Good-faith employee acquisition for the holder is excluded if it is not used or further disclosed without authorization.

Section 28-51-105(1) requires a prompt, reasonable, good-faith investigation into likely misuse. Resident notice follows if misuse occurred or is reasonably likely.

Resident, owner, and authority notice

A covered owner or licensee must tell an affected Idaho resident as soon as possible, in the most expedient time possible and without unreasonable delay under § 28-51-105(1). The section gives no fixed outside day count. A nonowner maintainer must notify and cooperate with the owner or licensee immediately following discovery under § 28-51-105(2) if misuse occurred or is reasonably likely; cooperation includes sharing relevant breach information.

Sections 28-51-104 to 28-51-106 do not prescribe a separate private-entity Attorney General or nationwide consumer-reporting-agency breach filing. The 24-hour Attorney General command in § 28-51-105(1) expressly applies when an agency discovers a breach; § 28-51-104(6) defines a private holder's primary regulator for enforcement purposes.

Delivery and substitute notice

Section 28-51-104(4) allows written notice to the most recent recorded address, telephone notice, or qualifying electronic notice. Substitute notice is allowed if direct notice would cost over $25,000, more than 50,000 Idaho residents need notice, or contacts are insufficient. It requires email where addresses exist, conspicuous website posting if there is a site, and major statewide media. The cited notice provisions do not itemize resident-letter contents.

What trips people up

The 24-hour rule is a public-agency duty. Section 28-51-105(1) places that deadline on an agency becoming aware of a breach; the private-entity resident deadline remains the as-soon-as-possible standard.

Police delay needs advice from the agency. Section 28-51-105(3) permits delay when law enforcement advises that notice would impede a criminal investigation. Notice resumes as soon as possible without unreasonable delay after the agency advises that the impediment has ended.

Existing procedures have conditions. Under § 28-51-106, a timely own-policy route or qualifying primary-regulator procedures may satisfy the notice duty if the section's conditions are met.

Common questions

Does the investigation itself start a fixed 30-day clock?

No. Section 28-51-105(1) specifies a prompt investigation and notice as soon as possible without unreasonable delay, without a fixed outer day count.

Is access without acquisition enough for a breach under this definition?

Section 28-51-104(2) requires illegal acquisition of the covered computerized data and a material compromise.
