What we do

VoteShield helps election officials in the United States keep voter data safe from interference, errors, and misinterpretation.

How we do it

Every state makes voter data publicly available. These voter files contain non-sensitive information on all registered voters in a particular state, and are commonly used by political parties and campaigns to facilitate voter outreach. VoteShield uses the data from these public files to track changes to voter records across the country.

How election professionals at the county and state level are using VoteShield.

‘‘VoteShield is an important component to help us ensure the integrity of Iowa’s voter data and elections. The system is available for all 99 county auditors to use. Auditors know their counties best, so if an anomaly is detected, they are able to investigate it themselves.’’

‘‘VoteShield offers an unparalleled external analysis of changes to voter rolls, which ensures that large scale voter registration irregularities are not occurring, and if they were, that we would detect them.’’
