A Privacy Enhanced Election Scheme with Spare Votes for Simplifying Possible Re-Voting Process

Abstract

In many daily election activities, it is quite often that we have to perform a re-voting process shortly after the previous one to make a decision on an additional subject, such as to resolve ties or to vote on a subject further than the previous one. With a typical election scheme, we usually have to repeat the entire election process again to finish the re-voting activity. This paper presents a new anonymous election scheme to simplify the possible re-voting process such that every voter can participate in the re-voting activity without a redundant re-registration action and the unlinkability between the two voting activities is preserved.
