信息技术的进步简化了我们生活中的许多过程。然而，在许多情况下，当新技术被引入时，信任问题就会出现，投票就是一个突出的例子。为了增加选民的信任度，目前的电子投票系统提供纸质审计跟踪（PAT），其使得能够对选举结果进行自动计票和/或手动审计。PAT可以仅包含人类可读和/或机器可读格式的加密投票或明文投票。以前的研究报告选民的隐私问题与PAT包含额外的信息（如QR码）以外的人类可读的明文投票。然而，省略这样的PAT负面地影响安全性和/或效率。因此，为了解决这些问题，我们在沟通过程中应用了保护动机理论的应对和威胁评估原则。我们在针对EasyVote系统的单独调查中对它们进行了评估[15]。结果表明，应对评估比威胁评估更有前途。虽然我们的研究结果提供了新的方向，解决隐私问题的电子投票的背景下，相应的限制需要考虑未来的用户研究。
Advances in information technology have simplified many processes in our lives. However, in many cases trust issues arise when new technology is introduced, and voting is one prominent example. To increase voters’ trust, current e-voting systems provide paper audit trails (PATs) which enable automatic tally and/or manual audit of the election result. PATs may contain only the encrypted vote or the plaintext vote in human-readable and/or machine-readable format. Previous studies report voter privacy concerns with PATs containing additional information (e.g. QR-Codes) other than the human-readable plaintext vote. However, omitting such PATs negatively influences security and/or efficiency. Hence, to address these concerns we applied the coping and threat appraisal principles of the protection motivation theory in the communication process. We evaluated them in separate surveys focused on the EasyVote system [15]. Results show that the coping appraisal is more promising than the threat appraisal approach. While our findings provide novel directions on addressing privacy concerns in the e-voting context, corresponding limitations need to be considered for future user studies.
