Design of the Electronic Voting System with Repetitious Voting Restricted by Face Recognition Technology

Face recognition technology is applied in the electronic voting system to restrict repetitious voting operations. The structure of the electronic voting system is firstly analyzed and then the application scenario of face recognition technology in restricting repetitious voting is introduced. For the electronic voting system's requirements on face recognition algorithm and the characteristics that the background of the voters' images is simple and the illumination condition varies little, this paper analyzes face detection method based on AdaBoost and face recognition method based on Eigenface respectively, both of which meet the requirements of this system, presents the design flow of the identity recognition sub-system based on face recognition with OpenCV, and describes functions of each model of the basic voting sub-system briefly. Finally, performance analysis of the identify recognition sub-system is shown in this paper.
