Crosscheck is an interstate data-sharing program between 28 states. Participating states send their entire voter file to a server in Arkansas. Kansas then downloads all of this data, runs a rudimentary name matching algorithm, and then uploads the results back to Arkansas. We have the passwords to every step in this process.
We’ve posted documents obtained by Indivisible Chicago as a result of FOIA requests to Florida and Illinois. The “yellow paper” redactions are our redactions of usernames and passwords carelessly sent via email. We have redacted instead of posting publicly, as we take the sensitivity of this data more seriously than the Illinois, Arkansas, and Kansas election authorities.
