Voting Receipt Verification for Electronic Ballot Accuracy

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The integrity of electronic voting systems is compromised due to the lack of a mechanism for voters to verify that their choices are accurately recorded, leading to voter confidence issues.

Innovation Solution

A device that generates a voting receipt, separate from the electronic voting machine, which allows voters to confirm their selections and provides an independent record of their votes, including a control unit, printing unit, and input device for acceptance or rejection of the recorded choices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If electronic voting machines are used to record voting choices, then voting efficiency and modernization are improved, but voter confidence and verification capability deteriorate because voters cannot review their recorded choices

Engineering Contradiction:

Improvevoting efficiencyVSAvoidvoter confidence

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system divides the voting verification function into a separate independent device from the electronic voting machine. The verification device receives voting data through a local area network connection and generates receipts independently, allowing voters to verify their choices without compromising the integrity of the original voting machine system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

An intermediary verification device is introduced between the electronic voting machine and the voter. This device receives voting choice data from the voting machine via network communication and presents it to the voter on a receipt, enabling verification without requiring the voter to directly interact with or review the electronic voting machine interface.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If voters are provided with a mechanism to verify their voting choices, then voter confidence is improved, but device complexity increases due to additional control units, printing units, and input devices

Engineering Contradiction:

Improvevoter confidenceVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The verification device integrates multiple functions into a single unit: it communicates with the electronic voting machine via network, processes voting data, generates printed receipts, and provides input mechanisms for voter verification. This multi-functional design reduces overall system complexity compared to having separate dedicated components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A device for generating a voting receipt is provided for use in a voting system. The voting system also includes an electronic voting machine configured to record the voting choices of a voter. The device communicates with the electronic voting machine via a local area network only, and receives from the electronic voting machine data indicating the voting choices of the voter. The device prints a voting receipt that indicates the voting choices of the voter. The voting receipt is a permanent record by which the voter can verify that their votes have been accurately recorded by the electronic voting machine. The device also includes an input device communicatively coupled to the control unit and permitting the voter to accept or reject the voting choices of the voter as indicated on the voting receipt.
