Digital Ballots and Democracy | Prof. Subodh V. Sharma | TEDxIITDelhi

Elections are the backbone of any functioning democracy, but for electoral systems to earn public trust, they must be transparent, secure, and understandable — not just to experts, but to every voter.

This talk explores how technology is offering solutions to conduct elections, from electronic voting machines and cryptographic audits to privacy-preserving voter rolls. Drawing on examples from around the world, the speaker highlights the core democratic principles that make a voting system trustworthy: verifiability, privacy, integrity, and auditability. The talk presents a vision for evolving election technologies in ways that improve transparency and verifiability, without overwhelming users or compromising existing infrastructure and robustness that large democracies demand. It concludes with practical, research-backed solutions that blend cryptography, usability, and public accountability. Dr. Subodh Sharma is an Assoc.
