Open Voter ID is like OpenID, to allow third-party websites to confirm registered voters' city of residence. This system uses scrambled government voter registration data to check a user's voter registration name and address. The only data revealed to the application website, is the user's city, and an app-specific user-ID.
Third-party websites can build services that are specific to the citizens of a city, without requesting nor storing sensitive information about each voter.
Voters can use multiple third-party websites that provide city-specific services, without revealing private information like home address.
