Deepfake is a portmanteau word combining “deep learning” and “fake.” Using powerful techniques from machine learning and artificial intelligence (AI), deepfakes can create convincing, but entirely fictional disinformation — images or audio — by mimicking and learning from given materials. Deepfake video and audio can appear so real as to be indistinguishable from the original.
A Taiwanese YouTuber was arrested on Monday last week for allegedly creating and selling deepfake porn videos featuring celebrities. The Criminal Investigation Bureau confirmed that it was Taiwan’s first case of a new type of crime that involves deepfakes employing AI algorithms.
For several years, deepfake technology has been a topic of heated debate in Western nations. There have been many deepfake videos of celebrities, such as former US president Barack Obama and Facebook CEO Mark Zuckerberg, and deepfakes have become weapons for parties interested in information warfare, not to mention that hundreds of actresses worldwide have become victims of synthetic porn.
The scary thing is that deepfakes can be used to fake bad things that a person has not done, as well as good things that a person did not do. There are many tools available for creating deepfakes — people do not have to be an information engineer to make them.
However, society’s deepest fear is that the technology used to generate deepfake porn not only hurts the victims, but could also be used to create deepfake video and audio files of presidents, government officials and political party leaders — thus disturbing law and order, undermining elections, causing political turmoil and the polarization of popular opinion. The social impact of deepfakes on public order should not be underestimated.
Presently, although some European and US law enforcement agencies and tech firms, such as Google and Microsoft, have invested in the development of deepfake detection software, to verify whether images have been modified or synthesized, these countermeasures are not enough to stop deepfake videos from circulating online and spreading disinformation.
Taiwan has so far not enacted laws and penalties that would regulate deepfake videos. The authorities should refer to international practices as soon as possible to bridge the gap.
The government should improve the accountability of online platforms so that they monitor users’ content; it should consider the manipulation of faces in video to be a crime; and it should enact regulations that clearly delineate the criminal, civil and administrative liabilities to deter crimes that employ new technology.

Because much of what former US president Donald Trump says is unhinged and histrionic, it is tempting to dismiss all of it as bunk. Yet the potential future president has a populist knack for sounding alarums that resonate with the zeitgeist — for example, with growing anxiety about World War III and nuclear Armageddon. “We’re a failing nation,” Trump ranted during his US presidential debate against US Vice President Kamala Harris in one particularly meandering answer (the one that also recycled urban myths about immigrants eating cats). “And what, what’s going on here, you’re going to end up in World War
Earlier this month in Newsweek, President William Lai (賴清德) challenged the People’s Republic of China (PRC) to retake the territories lost to Russia in the 19th century rather than invade Taiwan. He stated: “If it is for the sake of territorial integrity, why doesn’t [the PRC] take back the lands occupied by Russia that were signed over in the treaty of Aigun?” This was a brilliant political move to finally state openly what many Chinese in both China and Taiwan have long been thinking about the lost territories in the Russian far east: The Russian far east should be “theirs.” Granted, Lai issued
On Tuesday, President William Lai (賴清德) met with a delegation from the Hoover Institution, a think tank based at Stanford University in California, to discuss strengthening US-Taiwan relations and enhancing peace and stability in the region. The delegation was led by James Ellis Jr, co-chair of the institution’s Taiwan in the Indo-Pacific Region project and former commander of the US Strategic Command. It also included former Australian minister for foreign affairs Marise Payne, influential US academics and other former policymakers. Think tank diplomacy is an important component of Taiwan’s efforts to maintain high-level dialogue with other nations with which it does
On Sept. 2, Elbridge Colby, former deputy assistant secretary of defense for strategy and force development, wrote an article for the Wall Street Journal called “The US and Taiwan Must Change Course” that defends his position that the US and Taiwan are not doing enough to deter the People’s Republic of China (PRC) from taking Taiwan. Colby is correct, of course: the US and Taiwan need to do a lot more or the PRC will invade Taiwan like Russia did against Ukraine. The US and Taiwan have failed to prepare properly to deter war. The blame must fall on politicians and policymakers
