An Act relative to the integrity of state data systems

This bill strengthens data privacy for Massachusetts state systems by clarifying which activities qualify as "criminal justice duties" and restricting data sharing. It prohibits state agencies from sharing motor vehicle records with federal agencies for civil immigration enforcement, except when a valid warrant is presented. The bill also blocks access to criminal offender records for non-criminal justice purposes, like civil enforcement, and requires federal agencies to certify their use of such data solely for criminal justice. These provisions directly affect state agencies managing data (like the motor vehicle registry) and federal entities seeking access to state databases.
