Verifiability notion in e-Voting based on modified ThreeBallot system

The need to manage the voting process more efficiently, more flexible access, and faster results setting make e-voting systems a promising alternative. ThreeBallot was proposed to overcome the contradiction among some e-voting requirements, i.e. anonymity, privacy, and verifiability. Verifiability is an electronic voting system should provide a method to verify that the system works as expected. The verification of the original ThreeBallot method we call partial verification, because the voter only has a 1/3 belief that his voice exists and does not change. By making some modifications and additions to the ThreeBallot system, a system which allows for full verification is made (it is assured that three parts of the ballot do exist and remain unchanged). Unfortunately, by using original ThreeBallot, voter has only partial confidence in verifying his/her vote. We propose a modified ThreeBallot-based e-voting system to provide full verification without sacrificing either anonymity or privacy for verifiability notion.
