Mixed-Member Proportional Representation System
South Korea employs a Mixed-Member Proportional Representation (MMP) system, blending the qualities of majoritarian and proportional representation mechanisms. The system involves a two-segment approach to electing members to the National Assembly, combining the First-Past-The-Post (FPTP) and Proportional Representation (PR) formulas.
The larger share, 253 of the 300 seats, falls under the FPTP segment. Candidates vie for a simple plurality of votes in single-member constituencies. The candidate who receives the most votes in a district secures the seat.
In contrast, 47 seats are allocated through the PR segment. Parties submit closed party lists, and seats are filled based on the proportion of votes each party receives nationally, given they meet the threshold of either 3 percent of total valid votes or secure five or more seats in FPTP contests.
This dual approach enhances parliamentary representation. The FPTP segment fosters direct accountability and constituency service, allowing voters to choose specific individuals to represent their districts. The PR component ensures broader political perspectives are included, addressing the need for diversity in the legislative process.
However, the MMP system in South Korea leans towards the majoritarian aspect, with only 15.67 percent of seats allocated via PR. This nuance means that while smaller parties have a chance to gain representation, the system still predominantly benefits the major parties. This balance underscores the strategic creation of "satellite" parties, a maneuver by major parties to capitalize on the PR segment's rules, boosting their representation.
Gender representation is another aspect influenced by the MMP system. The 2024 elections witnessed a record 36 women elected, reflecting the evolving dynamics of South Korean politics. This increase from prior elections indicates a positive trend in gender inclusivity.
Election day involves a highly organized process, with polling stations set from 6 a.m. to 6 p.m. Voters identify themselves through fingerprint scans or ID cards, receiving two color-coded ballots—one for FPTP, another for PR. Security and transparency are paramount: ballot boxes are sealed and transported under police escort for counting.
The counting process combines technology and human oversight. Optical scanners sort ballots, which are then manually verified before being tallied by counting machines. This hybrid approach ensures accuracy and mitigates errors or fraud.
Various voting channels beyond the standard election day procedure highlight South Korea's commitment to inclusivity. Overseas voting, shipboard voting, early voting, and postal voting offer flexibility, accommodating voters' diverse needs.
Despite technical sophistication, challenges persist. Incidents like hidden spy cameras and AI-generated deepfakes remind us that maintaining election integrity is an ongoing battle. These issues underscore the need for vigilant election management.
Technological Integration in Voting Processes
In South Korea's voting landscape, technological integration plays a pivotal role in ensuring the processes are transparent, accurate, and secure. This integration begins at the very moment a voter steps into a polling station.
Fingerprint scanners and National ID card readers serve as the primary methods for voter identification. These technologies ensure that only eligible voters enter the system, minimizing the risk of identity fraud. By cross-referencing fingerprints with government databases in real-time, any discrepancies or attempts at impersonation can be quickly identified and addressed.
Once voter eligibility is confirmed, technology continues to streamline and enhance the voting process. Each voter receives two ballots—one for the FPTP segment and another for the PR segment of the MMP system. These ballots are then marked using an official red-ink rubber stamp, a system that prevents tampering compared to traditional pen or pencil markings.
Upon casting their votes, the operation at the counting centers is carefully organized, leveraging a combination of high-tech and human oversight to maintain the integrity of the process. When the polls close, sealed ballot boxes are securely transported to these centers under police escort, ensuring their safety from tampering or loss.
At these counting centers, optical ballot sorters take over the initial stages of ballot sorting. These machines rapidly sort ballots according to the markings, significantly speeding up a process that could be laborious if done manually. However, recognizing that machines are not infallible, human election officials conduct a manual verification of the sorted ballots. This dual approach ensures any errors by machines are caught and corrected, reaffirming the accuracy of the final count.
Next, the verified ballots are fed into counting machines that tally the votes. The use of such technology reduces human error, expedites the counting process, and provides an added layer of transparency, as machine-generated counts can be audited and verified against manual checks.
Technological integration is also apparent in the various alternative voting methods provided to ensure participation is as inclusive as possible. Early voting options include high-security setups where ballots for PR segments can be printed on-site, verified, and stored securely until counting. The use of satellite communication systems aboard ships and the adaptation of postal voting for those unable to visit polling stations highlight the flexibility and inclusivity of South Korea's election management system.
Despite these advancements, recent elections have demonstrated that technology alone cannot guarantee electoral integrity. The discovery of hidden spy cameras aimed at recording voting activities and the emergence of AI-generated deepfakes underscore the necessity for continuous advancements and vigilance in election security measures. These incidents, while isolated, pose significant threats to voter confidence and the overall integrity of the electoral process.
South Korea's technological integration in voting processes reflects a concerted effort to blend innovation with rigorous security measures, emphasizing the balance between modern convenience and traditional oversight. This sophisticated electoral framework not only improves efficiency and accuracy but also serves as a strong safeguard against potential errors and fraud, reassuring voters of the transparency and integrity of their democratic processes.
Inclusive Voting Channels
South Korea's election infrastructure also includes diverse voting channels to improve inclusivity and convenience for the electorate. This multifaceted approach ensures that various voter demographics—from those residing overseas to individuals with physical mobility constraints—can participate in the democratic process.
Overseas voting is a cornerstone of this inclusive strategy. Voters residing outside South Korea are afforded the opportunity to cast their ballots across a designated five-day period prior to election day. For the 2024 National Assembly elections, 220 polling stations were established worldwide, dispersed across 178 diplomatic missions in 115 countries. This initiative saw an impressive 92,923 overseas voters out of 147,989 registered, marking a turnout of 62.8 percent—the highest recorded for overseas voting in South Korea.
Shipboard voting exemplifies the country's commitment to inclusivity, catering specifically to maritime workers, such as those on deep-sea fishing vessels and passenger ships. Using satellite communication technology termed 'Shield Fax', these voters cast their ballots remotely from 2 to 5 April. This arrangement ensures that maritime workers, who are often geographically isolated, remain enfranchised and able to participate in national elections.
Early voting is another innovation that significantly improves accessibility and convenience. South Korea allows its citizens to cast their votes early during a two-day period typically five days before the main election day. This option is particularly beneficial for voters who might be away from their designated polling districts on election day. In the 2024 elections, nearly 14 million out of over 44 million eligible voters—amounting to a turnout of 31.28 percent—opted for early voting, reflecting a steadily increasing trend in its utilization1. The process involves a high level of organization and security; PR ballot papers for those voting outside their registration district are printed on-site and securely stored until counted, under continuous CCTV surveillance.
Postal voting extends the democratic reach to those unable to visit polling stations—such as the elderly, persons with disabilities, and hospitalized individuals. These voters can cast their ballots safely from their residences or healthcare facilities through the postal system, ensuring that physical limitations do not disenfranchise them.
The integrity of these voting channels, although generally strong, faced certain challenges in the 2024 elections. Instances of AI-generated deepfakes and the discovery of spy cameras in polling stations underline the need for ongoing vigilance and adaptive security measures. These incidents highlight the continual necessity for the election commission to address emerging threats in a rapidly evolving technological landscape.
South Korea's inclusive voting channels represent a concerted effort to make the electoral process accessible to a diverse population. By accommodating various voter needs—from overseas citizens to those with limited mobility—the nation underlines its commitment to comprehensive and participatory democracy. While these channels improve the inclusivity and convenience of voting, they also demand adaptive strategies to safeguard against potential security threats, ensuring that technology serves to strengthen, rather than compromise, electoral integrity.
AI and Deepfake Challenges
A significant challenge in South Korea's electoral landscape is the threat posed by AI and deepfake technology. These advancements, while offering numerous benefits, can also be exploited to undermine the integrity of elections. Instances of AI-generated deepfakes have become increasingly prevalent, necessitating strong legislative and technological responses.
One high-profile incident occurred during the 2024 elections, where 129 cases of AI-generated content related to election candidates were identified2. These deepfakes manipulated videos and speeches, distorting messages to mislead voters and exacerbate political division. An example featured a deepfake of Han Dong-hoon, the interim leader of the People Power Party (PPP), falsely comparing opponents to gangsters. Such incidents highlight the ease with which malicious actors can use AI to fabricate content that appears highly convincing.
The legislative response to these challenges has been swift and stringent. South Korea amended the Public Official Election Act, effective January 2024, to specifically ban the use of AI-generated deepfakes in political campaigns during the critical 90-day pre-election period3. Violators of this law face severe penalties, including up to seven years in prison or fines amounting to US$38,000 (50 million won). This legal framework aims to deter the creation and dissemination of misleading AI-generated content, thereby protecting the integrity of the electoral process.
To further bolster these efforts, the National Assembly and election monitors have introduced guidelines that mandate transparency in the use of AI for political communication. Any AI-assisted content must be clearly disclosed, ensuring voters are aware of the origins of the information they consume. This measure seeks to prevent the deception of the electorate by undisclosed AI-generated materials.
On the technological front, South Korean companies have developed solutions to detect and mitigate the risks associated with deepfake content. DeepBrain AI, the firm responsible for the Yoon avatar, has created software capable of identifying deepfake content. Additionally, Naver, the leading search engine in South Korea, has intensified its monitoring efforts to identify and counteract AI-generated comments and deepfakes. The platform has also implemented features allowing users to report election misinformation. These reports are managed through a dedicated center in coordination with the National Election Commission (NEC), ensuring a streamlined approach to addressing digital falsehoods.
Despite these proactive measures, challenges remain. Critics argue that bans on specific technologies like deepfakes may not fully encompass the broader issues related to AI in elections. They suggest that regulations should focus on the veracity and ethical use of content rather than the tools themselves. This perspective emphasizes the need for a comprehensive approach that includes ethical considerations in the development and deployment of AI.
Moreover, the enforcement of these regulations presents difficulties, especially when content is produced and disseminated from outside national borders. The use of virtual private networks (VPNs) by domestic internet users further complicates the tracking and removal of misleading content, potentially elongating investigations until after the election concludes.
While AI and deepfake technologies pose significant challenges to electoral integrity in South Korea, concerted legislative, technological, and procedural measures are being implemented to mitigate these risks. By focusing on transparency, stringent penalties, and strong detection mechanisms, South Korea strives to safeguard its electoral processes against the manipulative potential of AI-generated content. This balanced approach between leveraging technological advancements and maintaining democratic fairness sets a precedent for electoral integrity in the digital age.
Election Integrity and Security Measures
The integrity and security of South Korea's elections are paramount, given the fast-paced adoption of new technologies and emerging threats. Multiple layers of measures have been established to ensure that the electoral process remains strong, transparent, and trustworthy.
One significant security measure during recent elections was the detection and swift removal of spy cameras within polling stations. In the lead-up to the 2024 National Assembly elections, concealed cameras were discovered in approximately 40 polling and vote counting centers across major cities, including Seoul and Busan. These devices, cleverly disguised as communications equipment, were set up to capture voting activities covertly. The National Election Commission (NEC) acted promptly, collaborating with law enforcement to identify and eliminate these threats before they could impact voter privacy and election integrity.1
The involvement of election monitors plays a critical role in maintaining the security and fairness of elections. Monitors are tasked with observing various stages of the election process, from voter identification and ballot casting to counting and result transmission. They ensure that all procedures are conducted according to established guidelines, and any discrepancies are promptly addressed. During the 2024 elections, these monitors were particularly vigilant, ensuring that no irregularities went unnoticed, thereby bolstering public confidence in the electoral process.
The issuance of voluntary Election Integrity Guidelines for Technology Companies by the International Foundation for Electoral Systems (IFES) further strengthens the framework for secure elections. These guidelines, crafted in consultation with technology companies and election authorities worldwide, were designed to foster collaboration and communication between stakeholders. They provide a standardized set of practices aimed at enhancing election integrity and trust across the information ecosystem.
Guidelines emphasize the importance of information sharing, strong policies, and the establishment of clear processes for technology companies to follow during elections. For example, companies are encouraged to develop rapid response mechanisms for addressing disinformation and cyber threats. These practices protect the integrity of the electoral process and enhance the reliability of information accessed by voters.
Technology companies like Google, Meta, Microsoft, Snap Inc., and TikTok have committed to supporting these guidelines. They have pledged to:
- Prevent the spread of harmful content
- Ensure transparency in political advertising
- Maintain high-quality information dissemination
These measures are particularly crucial as they help mitigate the risks associated with disinformation campaigns and cyberattacks that could potentially disrupt or undermine elections.
The guidelines promote the development of strong partnerships between election authorities and the technology sector. By improving communication channels, these guidelines help overcome barriers presented by varied disinformation environments and diverse legal frameworks across different countries. This collaborative approach fortifies democratic institutions, particularly in newer or vulnerable democracies, ensuring that the integrity of elections is upheld globally.
Despite the proactive measures and advanced technologies in place, challenges persist, particularly with the enforcement of regulations against foreign-produced content. Domestic users' use of virtual private networks (VPNs) complicates the identification and removal of misleading information, highlighting the necessity for continued vigilance and adaptive strategies in the face of evolving threats.

Impact of Voting Technology on Election Outcomes
The integration of advanced voting technology in South Korea has significantly influenced the outcomes of elections, profoundly shaping voter turnout, representation, and the overall electoral process. Technological advancements offer greater convenience and inclusivity and fundamentally shift the dynamics of electoral engagement and outcomes.
The impact on voter turnout has been notable. The 2024 National Assembly election, with a record-high turnout of 67 percent, underscores the influence of technological conveniences like early voting, overseas voting, and electronic verification methods.2 By offering diverse, accessible voting options—such as early and postal voting or shipboard facilities using satellite communications—the system can accommodate a broader spectrum of voters, from overseas residents to those with limited mobility. This inclusivity reduces barriers, encouraging higher participation across varied demographics, which directly correlates with increased voter engagement and turnout.
Technological integration enhances the accuracy and transparency of the electoral process. With systems like optical ballot sorters and counting machines, South Korea ensures that the counting process is both swift and precise. This accelerates the declaration of results and mitigates human error, fostering trust in the electoral system. The transparent and secure transportation of ballots, along with continuous surveillance and manual verifications, reinforces the integrity of the vote count, ensuring that the final results reflect the true will of the electorate.
Technology has significantly impacted representation within the National Assembly. The Mixed-Member Proportional (MMP) system, augmented by advanced voting and counting technologies, facilitates a more accurate representation of the electorate's preferences. By combining majoritarian and proportional elements, the system allows for a more balanced composition of the parliament. While the First-Past-The-Post (FPTP) segment ensures direct constituency representation, the proportional representation (PR) segment enables smaller parties to gain a foothold, providing a platform for diverse political voices.
The increased use of early voting and other alternative voting methods has contributed to changes in electoral outcomes. These methods tend to favor candidates and parties that are well-organized and capable of mobilizing their voter base early. Consequently, political strategies have evolved, with campaigns now placing significant emphasis on securing early votes, often customizing their messages and outreach efforts to the demographics that are more likely to utilize these options. This shift has potentially altered traditional voting patterns, making election results more reflective of a broader temporal snapshot of voter preferences.
Representation in terms of gender has also seen progress, partly due to the facilitated participation enabled by technological advancements. The 2024 elections saw a record 36 women elected to the National Assembly, indicating a positive trend in gender inclusivity.3 The efficient and secure voting process, which simplifies participation, likely plays a role in encouraging more women to run for office and vote, gradually shifting the gender dynamics within the political landscape.
However, while technology enhances inclusivity and accuracy, it also presents challenges. The incidents of deepfake content underline the risks of misinformation in the digital age. Despite stringent regulations and sophisticated detection technologies, the manipulation of digital content remains a formidable challenge. Politically motivated misinformation can skew public perception and influence electoral outcomes in subtle but significant ways, emphasizing the need for ongoing and adaptive security measures.
The transparency and efficiency brought about by technology have instilled greater confidence in the electoral system among voters. This trust is crucial in ensuring voter participation and acceptance of election results, even in tightly contested races. The methodological rigor and transparency afforded by technological integration mean that the electorate can have greater faith that the outcomes are legitimate and reflect their collective decision.
