From its website, https://ericstates.org/, the Electronic Registration Information Center, also known as ERIC, is a "non-profit organization with the sole mission of assisting states to improve the accuracy of America’s voter rolls and increase access to voter registration for all eligible citizens."
"The seven states that formed ERIC in 2012 included Colorado, Delaware, Maryland, Nevada, Utah, Virginia and Washington. Since that time, 31 states and the District of Columbia have signed on as members. The system is controlled by the states. Each state designates a representative to the ERIC Board of Directors.
Each member submits at a minimum its voter registration and motor vehicle licensee data to ERIC. The data includes names, addresses, date-of-birth, last four digits of the social security number. Each member state receives reports that show voters who have moved within their state, voters who have moved out of state, voters who have died, duplicate registrations in the same state, and individuals who are potentially eligible to vote but are not yet registered. States may request a report identifying voters who appear to have voted twice within the state in the prior federal election, voted in more than one state in the prior federal election, or who voted on behalf of a deceased voter in the prior federal election."
This collaborative system is a data-driven effort that prevents voter fraud and helps the various secretaries of state maintain accurate voter rolls. Other than the potential risk of data theft <Private data such as date of birth and the last four digits of the Social Security number are protected using a cryptographic one-way hash and then transmitted to ERIC> this nonpartisan effort is in the toolbox and seems to be working because there were only a few instances voting anomalies, despite a nationwide partisan effort to prove otherwise.
