Idaho HB 744 regulates the capture, storage, disclosure, and destruction of biometric identifiers (retina/iris scans, fingerprints, voiceprints, hand/face geometry) for commercial purposes. Before capturing a biometric identifier, a person must inform the individual and obtain consent; consent cannot be inferred from publicly available images unless the individual themselves made the data public. Possessors must protect biometric data with reasonable care, destroy it within one year of purpose expiration, provide a revocation mechanism, and may only disclose it under narrow exceptions. The law creates a broad AI training exemption: processing or storage of biometric identifiers for developing, training, or evaluating AI models or systems is exempt unless the system is used to uniquely identify a specific individual. Enforcement is exclusively through the Attorney General, with civil penalties up to $25,000 per violation.
