Introduction

Learn the basics of the Scantegrity voting system; what it is and how it works.

This presentation gives an overview of the latest Scantegrity system. You may also be interested in the Wikipedia article for a quicker introduction. If you want more technical detail, we suggest starting with our IEEE paper which introduces the system, and then reading about the latest innovations in our most recent EVT paper.
