CastVote

CastVote is a term used for electronic voting software and services that enable voters to cast ballots in elections. It can refer to generic voting concepts as well as specific products developed by different vendors. In typical deployments, CastVote systems provide an interface for selecting options, submitting ballots securely, and reporting tallies to election authorities.

Features commonly associated with CastVote include verified voter authentication, integrity-protected ballots, cryptographic verification options, and comprehensive audit logs. Many implementations support end-to-end verifiability, optional voter receipts, and accessibility features for users with disabilities. Deployments may be web-based, use ballot-marking devices, or operate as offline casting tools with later upload to a central system.

Security and privacy considerations emphasize encryption, tamper-evident logs, role-based access controls, supply-chain risk management, and conduct of risk-limiting audits. Compliance with local election laws and standards—such as national or provincial guidelines—often shapes system design and testing, including independent security testing.

History and governance: The approach emerged with the adoption of electronic voting in the late 20th century and has evolved to emphasize verifiability and transparency. Many jurisdictions require independent testing, documented methodologies, and public threat modeling to maintain trust.

Challenges and criticism: Critics note potential vulnerabilities, reliance on vendor integrity, and the need for rigorous, verifiable audits. Proponents argue that well-designed CastVote systems can improve accessibility and efficiency when combined with transparent governance.
