Amends TCA Title 2.

Tennessee HB0999 amends Title 2 of the Tennessee Code Annotated to require that all ballots cast in primary or general elections include a visible secure watermark as a security feature. This bill affects all voting methods, including voting machine ballots, paper ballots, and absentee ballots, and mandates that the coordinator of elections define the watermark's method, type, and placement. Key provisions include the requirement for digital images of scanned ballots to be maintained and posted for public review, and the establishment of auditing procedures for ballot images without reliance on machine coding.
