Abstract
The existing voting systems have been studied, with a special focus on E2E verifiable voting systems, which are considered as the newest class of voting systems. The Bingo Voting system was selected being one of the end-to-end cryptography verifiable voting systems that can be adapted to suit the users in developing societies; this system provides verifiable correctness based on a trusted random number generator. This thesis presents some of proposed modifications to the Bingo Voting system. We representation the vote by short number and image linked it instead of a long number in the original Bingo system to simplify the use of the system. The modified proposed system is called Picture-Bingo Voting system. A comparative security and performance evaluation between Picture-Bingo Voting and Bingo Voting has been conducted. Security of Picture-Bingo was improved at the cost of an increase in storage requirements
