Audit mechanism for detecting voting manipulation in electronic voting systems

Electronic voting systems are prone to faults, errors and intentional attacks. One risk is the addition of fake votes (stuffing) that can be carried out by an external or internal entity. There are several audit mechanisms intended to prevent, detect and / or mitigate any threats that could undermine the election results. This paper presents a review and evaluation of the different mechanisms used to conduct an election audit for electronic voting systems. Also, an audit mechanism to detect ballot stuffing or any other manipulation on votes is presented.
