After years of deliberation, planning, coordination, legislation and recruitment, a highly anticipated new Cabinet-level agency, the Ministry of Digital Affairs, was approved by the Legislative Yuan in December last year and is to be formally established and start operations next month.
Officially, the ministry is tasked with covering five sectors: information, telecommunications, media communications, cybersecurity and the Internet.
Part of the new ministry’s responsibility is the establishment of digital infrastructure to support policy areas, including information security protection, wireless and broadband communications, and the digitization of government.
However, its most important mission is to bring to bear the full might and resources of a Cabinet-level agency to advocate, advance and facilitate the development of industry segments in which Taiwan is generally considered to be less competitive globally. These are data, information technology services, software, media content and digital content.
Focusing on the data industry, the idea that it is the “21st century’s oil” has become widely accepted. In the digital economy, user data and content can be exploited to enhance the efficiency of day-to-day operations. This is evident in that four of the world’s five most valuable companies by market capitalization heavily exploit user data to improve the quality of their products and services, and to increase their competitiveness.
In Taiwan, the concept of a “data economy” has been prevalent since President Tsai Ing-wen’s (蔡英文) first term in office. For the past couple of years, the government has made some effort to facilitate a data economy, including by promulgating personal privacy protection regulations, opening up government-owned non-personal data, developing data de-identification technologies, and standardizing formats and protocols for data sharing.
However, the cumulative progress so far has not been as impressive as expected, despite vibrant data analytics and the constant emergence of artificial intelligence (AI) start-ups.
A major thrust in a data economy is enabling multiple data sources to be aggregated to fully extract their collective value.
However, in Taiwan it is difficult to share data from disparate sources, if not impossible. The main obstacle is not data privacy, but ownership protection. When the owner of a data set agrees to share it, how their ownership rights and interests are protected is not clearly defined.
As a result, even though everyone agrees that the National Health Insurance database is a treasure trove for novel biomedical applications, no such commercial exploitation is possible because its owner, the Ministry of Health and Welfare, insists that the database be accessible only by authorized personnel who are on site, never over a network.
To take the data sharing challenge one step further, consider multiple hospitals that are contemplating whether to contribute their own medical record databases to a global pool for commercial application.
They have two main concerns:
First, how to retain ownership of the data and ensure that their database is not stolen.
Second, how to fairly estimate the contributions of their database to the outcomes of the cooperative effort to calculate profit distribution.
In the past few years, “federated learning” technology — also known as collaborative learning — has been touted as a solution to address the first concern. In reality, it is a partial solution at best, because it only ensures that a data set never physically leaves its owner, but does not prevent an adversary from stealing it by training an AI model and piggybacking part of it onto the AI model, which is eventually sent out.
This method of stealing data has been successfully demonstrated — it is not merely a theoretical threat.
As for the second concern, the situation is even more grim, as no practical solutions have emerged.
To enable more pervasive data sharing and collaboration, which would help accelerate the development of Taiwan’s data economy, the digital affairs ministry should make the best of the fresh political capital associated with being a new agency and develop a government-backed data sharing platform that effectively addresses the two concerns, perhaps using some combination of technological solutions and statutory protections.

When Chinese President Xi Jinping (習近平) sits down with US President Donald Trump in Beijing on Thursday next week, Xi is unlikely to demand a dramatic public betrayal of Taiwan. He does not need to. Beijing’s preferred victory is smaller, quieter and in some ways far more dangerous: a subtle shift in American wording that appears technical, but carries major strategic meaning. The ask is simple: replace the longstanding US formulation that Washington “does not support Taiwan independence” with a harder one — that Washington “opposes” Taiwan independence. One word changes; a deterrence structure built over decades begins to shift.
Taipei is facing a severe rat infestation, and the city government is reportedly considering large-scale use of rodenticides as its primary control measure. However, this move could trigger an ecological disaster, including mass deaths of birds of prey. In the past, black kites, relatives of eagles, took more than three decades to return to the skies above the Taipei Basin. Taiwan’s black kite population was nearly wiped out by the combined effects of habitat destruction, pesticides and rodenticides. By 1992, fewer than 200 black kites remained on the island. Fortunately, thanks to more than 30 years of collective effort to preserve their remaining
After Chinese Nationalist Party (KMT) Chairwoman Cheng Li-wun (鄭麗文) met Chinese President Xi Jinping (習近平) in Beijing, most headlines referred to her as the leader of the opposition in Taiwan. Is she really, though? Being the chairwoman of the KMT does not automatically translate into being the leader of the opposition in the sense that most foreign readers would understand it. “Leader of the opposition” is a very British term. It applies to the Westminster system of parliamentary democracy, and to some extent, to other democracies. If you look at the UK right now, Conservative Party head Kemi Badenoch is
A Pale View of Hills, a movie released last year, follows the story of a Japanese woman from Nagasaki who moved to Britain in the 1950s with her British husband and daughter from a previous marriage. The daughter was born at a time when memories of the US atomic bombing of Nagasaki during World War II and anxiety over the effects of nuclear radiation still haunted the community. It is a reflection on the legacy of the local and national trauma of the bombing that ended the period of Japanese militarism. A central theme of the movie is the need, at
