Decentralized Trust: Visual Cryptography for Transparent E-Voting Solutions
M Asmitha, C. R. Kavitha · 2024
E-voting system is a digital mechanism that enables people to vote electronically, ensuring confidentiality, security, and transparency. Visual cryptography (VC) is a cryptographic technique where a secret image is divided into two or more shares, and only by superimposing these shares can the secret be revealed. When combined, visual cryptography offers a unique and secure way to enhance e-voting systems, providing features such as transparency, privacy, and tamper-proof mechanisms. It has an exceptional way of splitting a secret image into n pieces such that each piece reveals no information about the whole. Whenever these shares are stacked or overlaid, the original image is recreated again. This means that every share taken alone does not provide any clues to what is in the hidden content, and so it is a very good option for safeguarding shared information. In terms of electronic voting systems, visual cryptography can be used as a possible solution to addressing issues such as vote tampering, coercion and confidentiality of voters. This paper aims to enhance the security and confidentiality of electronic voting systems through the implementation of visual cryptography. A high level of security and verifiability can be realized with e-voting system through visual cryptography.
