As Internet voting can take place regardless of a voter's location, the participation rate of the voters would be increased and economic costs will be reduced. But the drawback of it is that all participants have to trust the election management server. If the server colludes with the specific candidate, the other candidates cannot prove rigged election. In addition, majority of researches on Internet voting are mainly focused on the voting restricted by the region and the country. Thus, it's not appropriate for the election in Internet community such as YouTube channels. As the Internet community is composed of members from all around the world, the new type of voting model is needed. In this study, we propose the smart contract based Internet voting model applicable on the blockchain network. The proposed smart contract model consists of candidate registration, voter registration, voting and counting stages. In the proposed model, anonymity of the voter is assured in the voter registration and voting stages, and all candidates can confirm the fairness of the election in the counting stage.

Electronic voting has been followed by a lot of research as it provides convenience to voters and increases participation rates. Nevertheless, electronic voting has not been widespread yet. The existing electronic voting system does not guarantee credibility, and there arises a question on the security that the voting could be forged or altered by the attack to the central server. In this paper, we proposed blockchain based systems to solve the problems in electronic voting. Although the blockchain may guarantee the security of transaction data, there have been only a few electronic voting systems implemented using the blockchain. We developed blockchain enabled voting and brought out some of its related legal, technical and operational challenges to enforce more security in voting. Unlike centralized voting, the systems could enforce security and solve the problems such as forgery or alteration of transaction data caused by hacking or any attempts to gain control of the central server system.

Fast diffusion of personal computer and network, and developed security technology are augmenting specific gravity of convenient and safe electronic voting system supplementing much problems of existent off-line vote form. But in spite of enlargement of these weight, much limitations are extravagant. Specially, problem that secure voter\`s anonymousness and accuracy of poll can be important urea that judge if electronic voting system can be applied actually. Also, problems such as buying and selling of vote remain to subject that must solve yet. In this paper, we introduce items that is considered to design the safe electronic voting system, and present limitation of electronic polling system announced in [1]. And we propose improvement way. Improved protocol keeping advantages that is presented in [1], designed to keep away voter\`s anonymousness defamation by conspiracy of Election Administration Committee and Totaling Committee, and block unlawful election intervention as original.

최근 전자투표 시스템에 대한 투표자의 신뢰성을 높이기 위해 영수증을 발급하는 기술에 대한 연구가 활발히 진행되고 있다. 전자투표 영수증은 투표자가 자신이 투표한 결과가 최종집계에 올바르게 반영되었음을 확인할 수 있어야 하며, 매표 방지 기능도 함께 가지고 있어야 한다. 본 논문에서는 기존의 연구되었던 기술 중에서 일반 용지 및 프린터를 이용하여 검증 가능한 영수증을 발급하는 전자투표 시스템을 구현하고자 한다.

네트워크의 발전과 관련해 많은 응용 분야들이 연구되고 있는데, 그 중에서도 암호학을 이용한 전자 투표의 비중이 증대되고 있다. 이러한 측면에서 살펴볼 때 선거관리위원회(선관위)는 전자 투표를 총괄하며, 동시에 투표 결과를 집계해서 공표하는 기능까지 가지고 있는 중요한 기관이다. 그러나 이러한 위치의 선관위가 부정을 저지를 경우 투표에 있어 치명적인 악영향을 미칠 것을 두 말할 나위도 없다. 따라서 본고에서는 선관위가 저지를 수 있는 부정의 요소를 파악하고, 기존의 방식을 고찰하여 보다 더 안전하고 효율적인 선관위의 부정 방지 방식을 제안한다.

Current electronic voting systems are not sufficient to satisfy trustworthy elections as they do not provide any proof or confirming evidence of their honesty. This lack of trustworthiness is the main reason why e-voting is not widespread even though e-voting is expected to be more efficient than the current plain paper voting. Many experts believe that the only way to assure voters that their intended votes are casted is to use paper receipts. In this paper, we propose an efficient scheme for issuing receipts to voters in an e-voting environment using the well-known cut-and-choose method. Our scheme does not require any special printers or scanners, nor frequent observations of voting machines. In addition, our scheme is more secure than the previous schemes.

This study attempts to analyze gender gaps in voter turnout for three different types of elections held since 2017 at the aggregate level using the Central Election Management Commission's turnout data, paying attention to the importance of women's voting. The findings are as follows. First, modern gender gaps in voter turnout at the aggregate level are confirmed in most regions regardless of election types. Second, the gender gap in turnout varies with age. The gender difference is verified in the "widowhood effect," where turnout decreases in the oldest-old. In the new voter group, modern gender gaps appear in most regions. The reversed gender difference in turnout in the late 20s, which reflects the Korean society's characteristics, is confirmed in all elections. Third, it is unclear whether the reverse gender gap in turnout becomes more pronounced in urbanized districts. As urbanization progressed, modern gender differences in voter turnout across age groups are observed at the population-based size level. Paradoxically, the modern gender gap tends to be weak and turns into the traditional gender gap in younger age groups (in the late thirties) in Gangnam-gu and Seocho-gu, the most modernized districts in Seoul. These results show that the modern gender gap in turnout is now a common phenomenon and continues to be strengthened by newly recruited voters in Korea. Thus we should pay more attention to female voters' political behavior and a new approach beyond the developmental theory to understand the causal mechanism to generate the modern gender gap in voter turnout.

블록체인 기술은 4차 산업혁명 시대를 이끌어 나갈 핵심기술로 거론되고 있으며 높은 보안성을 장점으로 가상화폐, 사물인터넷, 등 다양한 분야에서 활용되고 있다. 본 연구는 캠퍼스 내에서 진행되는 투표를 위한 전자투표시스템을 제작하고, 보안성을 강화하기 위해 블록체인기술을 활용하였다. 기존의 분산원장네트워크를 활용하는 방식과 달리, 소규모 투표에 적합하도록 개인 간의 가상화폐 거래과정을 활용한 투표시스템을 구축하였다. 이를 통해 기존의 블록체인기술기반 전자투표시스템의 단점인 초기 서버구축비용의 소요를 줄일 수 있을 것으로 기대한다.

블록체인은 분산 원장 기술 중 하나로 여러 개의 노드들이 참여하며, 이 노드들 간의 합의 알고리즘을 통하여 데이터의 위 변조를 막고, 이미 기록된 데이터를 바꿀 수 없는 구조를 장점으로 가진다. 이러한 특성 때문에 블록체인은 신뢰성이 중요시되는 플랫폼에 많이 적용이 되며 많은 플랫폼 중 전자투표의 중요한 기술로서 인식되고 있다. 전자투표는 선거의 모든 과정을 전자화 하여 선거를 관리하는 사람이나 투표자 모두에게 편리함을 제공하는 시스템으로 기술적인 보안성이나 시스템의 안정성이 완벽하게 보장되지 않아 유권자들에게 신뢰를 주지 못해 현실에서 쉽게 적용하지 못하고 있다. 이러한 문제를 해결하기 위해 본 논문에서는 블록체인을 적용하여 투표의 변조를 막고 유권자들의 신뢰와 시스템의 안정성을 제공하는 전자투표 시스템을 제안한다.

웹의 점진적 발전에 맞춰 웹 프로그래밍 언어도 계속적으로 발전해 나아가고 있으며, 기존 HTML에서 더욱 진화된 HTML5는 다양한 멀티미디어 기능과 그래픽 효과를 표현할 수 있다. 최근 각 분야에서 인터넷 활용이 점점 증가하고 있는데, 투표방식에서도 전통적인 방식에서 인터넷을 활용한 인터넷 투표 방식을 도입하려는 사례가 늘어가고 있다. 인터넷 투표는 부정투표와 같은 보안적 문제점이 있는데, 본 논문에서는 HTML5를 기반으로 JSP를 이용하여 인터넷 투표의 보안성을 강화하고 HTML5에 기반 한 기술을 활용하여 시스템을 구축하였다.
