A permanent, centralized electronic database of voters, to be known as the central voter file, is established with the offices of the secretary of state and county auditors linked together by a centralized statewide system. The county auditor is chief custodian of the central voter file records in each county. The secretary of state shall maintain the central voter file and provide training and documentation that users who have been granted access to the system shall follow. The central voter file must be accessible by the secretary of state and all county auditors for purposes of preventing and determining voter fraud, making changes and updates, and generating information, including pollbooks, reports, inquiries, forms, and voter lists.
