Secure Online Voting System Using Biometric and Blockchain

Abstract

Elections play an important role is democracy. If the election process is not transparent, secure and tamper proof then the reliability and authenticity of whole process is at stake. In this paper, we have discussed online voting system which fulfills all the above system requirements. We have addressed the issue of user authentication through iris recognition. We have used One Time Password (OTP) to have additional security check. We have also taken care that one valid user should not cast multiple votes. Use of Blockchain is the another security measure implemented in order to provide decentralized, tamper proof storage of data related to users biometric, personal details and votes casted by them. Thus we are not only focusing on user authenticity but also data security is also taken into consideration. The performance of the system has been tested for users from different age group and different background and its inference is presented.
