Personal Information Protection Act, data breach notification

cite 815 ILCS 530/1 et seq. (P.A. 94-36, eff. 2006-01-01) stage In effect since 2006-01-01 reviewed 2026-08-23

Requires a data collector, government agency or private entity, holding computerized personal information of Illinois residents to notify affected residents of a security breach in the most expedient time possible and without unreasonable delay.

Personal information expressly includes unique biometric data used to authenticate an individual, such as a fingerprint, retina or iris image, or other physical or digital biometric representation, alongside a name paired with a Social Security number, account number, or medical information.

A data collector must notify the Illinois Attorney General once a single breach affects more than 500 Illinois residents, and a State agency must do so above 250 residents; a violation is an unlawful practice under the Consumer Fraud and Deceptive Business Practices Act.
