Verifiable Classroom Voting

端對端可驗證的電子投票應用程序

With this verifiable classroom voting app, users have the ability to easily access, participate in and view the results of existing elections via an Android device.

For each election, users have the ability to answer a variety of questions. This app supports four types of questions: 1) single-choice selection; 2) multiple-choice selection; 3) free numeric input, and 4) free text input. For the first two types, users can verify the integrity of the tally without compromising privacy. This is based on the implementation of a Direct Recording Electronic with Integrity (DRE-i) cryptographic protocol. For every vote cast, a receipt is returned which can then be checked against the eVoting Bulletin Board at https://easyevoting.com/classroombulletinboard.php

The results to a finished election can then be viewed as bar charts or text depending on the format of each question.

The app works on any Android mobile device, both smartphones and tablets.

The app was initially written by Carlton Shepherd, and later maintained and improved by Dylan Clarke and Horia Druliac, as part of an ERC-funded project on “self-enforcing e-voting” (PI: Prof Feng Hao).
