To control the COVID-19 pandemic during the New Year holiday, the Ministry of Health and Welfare launched Skynet — a smartphone-based GPS tracking system to enforce quarantine or health management restrictions — and used it to catch people who breached the guidelines by going to a year-end concert by rock band Mayday.
As the system shares its name with China’s massive surveillance network, people are worried whether it monitors everyone in Taiwan. In reaction, the ministry immediately changed the name to Electronic Fence 2.0 and insisted that its implementation is legally sound.
However, the question is if the ministry’s authorization based on the Communicable Disease Control Act (傳染病防治法) is clear enough. According to Article 44, the ministry may order mandatory treatment, isolation or other necessary means to curb the spread of an infectious disease.
The Central Epidemic Command Center (CECC) implemented five measures based on the article: health surveying, tracking, self-management and self-observation, as well as home isolation.
However, as the number of people under restrictions increases, the conventional ways of monitoring — visiting people at home or calling them by telephone — have become inadequate to meet the needs of the developing situation and must be assisted by technology.
According to the law, those who are subject to electronic surveillance can be divided into two categories. The first category is regulated in the Sexual Assault Crime Prevention Act (性侵害犯罪防治法), which allows monitoring of an offender on parole or probation in the implementation of their sentence after obtaining permission by a prosecutor. The second category is regulated in the Code of Criminal Procedure (刑事訴訟法), which allows monitoring to prevent a defendant from fleeing after being granted suspension of detention, and requires permission by a court.
These types of monitoring are based on nonstop GPS tracking.
However, the intensive monitoring applied in criminal law cannot be used for the prevention and control of a pandemic, as people under quarantine are neither defendants nor prisoners. Therefore, only base stations operated by Taiwan’s telecoms can be used to track smartphone signals to monitor if a person contravenes the guidelines.
This kind of tracking provides only information about whether the monitored person is moving about without permission, but it does not allow for an immediate, accurate localization of the phone’s owner.
The new system marks a change from passive to active monitoring, as it obtains data from base stations around the nation and monitors whether a person under quarantine or self-health management enters a specific area, for example where Mayday holds a concert.
Although it does not provide continuous monitoring, it allows for accurate tracking similar to a GPS-based system, raising doubts as to whether it contravenes the principle of proportionality.
Even though the ministry and the CECC are authorized to adopt pandemic prevention measures, electronic monitoring is not regulated by the Communicable Disease Control Act, or the Special Act for Prevention, Relief and Revitalization Measures for Severe Pneumonia with Novel Pathogens (嚴重特殊傳染性肺炎防治及紓困振興特別條例).
This could lead to arbitrary interpretation and decisions that could contravene human rights.
Therefore, legislators must introduce legal amendments, stipulating that data obtained for pandemic prevention cannot be used for other purposes, as well as the data retention period.

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
