Vice Premier Cheng Wen-tsan (鄭文燦) was accused of having an “illicit affair” a few months ago, after a video showing a man, who resembled Cheng, entering a hotel room with a woman was circulated online. In response, Cheng has said multiple times that the man in the video was not him, and he has asked his lawyer to file a defamation lawsuit to prove his innocence.
The Criminal Investigation Bureau, which was supposed to determine whether the video was generated by artificial intelligence (AI), said that the result was “inconclusive.”
The assessment was conducted using US and Netherlands-developed tools like Deepware and Sensity, with the former spotting no signs of deepfakes due to the video’s poor resolution, while the latter assigned it a 65 percent possibility of being a “deepfake” video. As the two programs did not show consistent results, the bureau could only declare the case “inconclusive.”
It has been reported that the two programs with equipment are priced at NT$20 million (US$637,471), and that it only takes half an hour to get results, which should mark it as the latest technology in the field of deepfakes. What is surprising is that even with the state-of-the-art technology, the police still have no way of obtaining conclusive results. This is remarkable, because not only did the investigation fail to prove Cheng’s innocence, it also assessed the video as having a 60 percent possibility of having been made with deepfake technology. What is even more perturbing is that if the video was faked, this case shows that the police do not have the technology to accurately detect deepfake content. This could be worrying if the technology falls into the wrong hands.
With the presidential election on Jan. 13 entering its final stages, the three presidential tickets are in a tight race, polls show.
If before the election someone spreads content that could damage the presidential candidates’ images and influence voters’ decisions, that could easily become a turning point.
Similar tricks have been tried in elections before. Two decades ago, someone leaked a fake audio tape to accuse then-Kaohsiung mayor Wu Den-yih (吳敦義) of having an affair during the Kaohsiung mayoral election, resulting in Wu losing to now Representative to Japan Frank Hsieh (謝長廷).
Compared with fake audio, deepfake videos bring a larger and more visual impact. Considering that we are in the digital age where videos could go viral in an instant, there could be no guarantee that such a trick would not take place the day before the election.
The Central Election Commission, the Ministry of Digital Affairs, the National Communications Commission, the National Police Agency and other agencies, as well as the government and opposition parties and campaign teams, should collaborate to take precautions by formulating crisis management and response strategies so that the public does not panic and campaigns do not fall into disarray if such a thing happens. Such an event would not only put Taiwan’s democracy to shame, it would also sow the seeds of even greater discord.

In the US’ National Security Strategy (NSS) report released last month, US President Donald Trump offered his interpretation of the Monroe Doctrine. The “Trump Corollary,” presented on page 15, is a distinctly aggressive rebranding of the more than 200-year-old foreign policy position. Beyond reasserting the sovereignty of the western hemisphere against foreign intervention, the document centers on energy and strategic assets, and attempts to redraw the map of the geopolitical landscape more broadly. It is clear that Trump no longer sees the western hemisphere as a peaceful backyard, but rather as the frontier of a new Cold War. In particular,
When it became clear that the world was entering a new era with a radical change in the US’ global stance in US President Donald Trump’s second term, many in Taiwan were concerned about what this meant for the nation’s defense against China. Instability and disruption are dangerous. Chaos introduces unknowns. There was a sense that the Chinese Nationalist Party (KMT) might have a point with its tendency not to trust the US. The world order is certainly changing, but concerns about the implications for Taiwan of this disruption left many blind to how the same forces might also weaken
As the Chinese People’s Liberation Army (PLA) races toward its 2027 modernization goals, most analysts fixate on ship counts, missile ranges and artificial intelligence. Those metrics matter — but they obscure a deeper vulnerability. The true future of the PLA, and by extension Taiwan’s security, might hinge less on hardware than on whether the Chinese Communist Party (CCP) can preserve ideological loyalty inside its own armed forces. Iran’s 1979 revolution demonstrated how even a technologically advanced military can collapse when the social environment surrounding it shifts. That lesson has renewed relevance as fresh unrest shakes Iran today — and it should
As the new year dawns, Taiwan faces a range of external uncertainties that could impact the safety and prosperity of its people and reverberate in its politics. Here are a few key questions that could spill over into Taiwan in the year ahead. WILL THE AI BUBBLE POP? The global AI boom supported Taiwan’s significant economic expansion in 2025. Taiwan’s economy grew over 7 percent and set records for exports, imports, and trade surplus. There is a brewing debate among investors about whether the AI boom will carry forward into 2026. Skeptics warn that AI-led global equity markets are overvalued and overleveraged
