Senate Bill 369 aims to enhance the protection of personally identifiable information (PII) in Wisconsin by prohibiting state agencies from sharing such data with the federal government unless it has been masked or anonymized. The bill defines "personally identifiable information" and "state agency," establishing clear guidelines for data sharing. It allows exceptions for state agencies, legislators, and courts to share unmasked data when necessary to comply with state or federal laws or to fulfill official duties.

Additionally, the bill introduces a civil cause of action for individuals who are harmed by negligent violations of this prohibition. Those found liable for such violations may be required to pay actual damages, exemplary damages up to $1,000, and cover reasonable attorney fees. This legislation seeks to safeguard citizens' privacy while still allowing for necessary governmental functions.
