Brain-computer interfaces: neural data.

Senator Umberg's legislation addressing neural data privacy establishes new requirements for businesses operating brain-computer interfaces (BCIs) in California, adding specific protections for data collected directly from users' brains. The measure builds upon existing consumer privacy frameworks by creating targeted rules for this emerging technology.

The bill defines BCIs as systems enabling direct communication between a person's brain and external devices, while establishing two core obligations for companies providing these interfaces. First, neural data collected through BCIs must be used exclusively for its original intended purpose. Second, companies must delete this data once that purpose has been fulfilled. These requirements apply to any person or entity making BCIs available to California residents.

This measure operates within California's existing privacy protection system, complementing the California Consumer Privacy Act's provisions on sensitive personal information and the California Privacy Rights Act's enforcement structure through the state Privacy Protection Agency. The bill's authors note it aligns with and furthers the objectives of these foundational privacy laws while addressing the distinct challenges posed by direct brain-computer connections.
