The use of deepfakes can sow doubt, creating confusion and distrust in viewers

In early March, a manipulate­d video of Ukrainian President Volodymyr Zelenskyy was ciruclated. In it, a digitally generated Zelenskyy told the Ukrainian national army to surrender. The video was circulated online but was quickly debunked as a deepfake — a hyper-realistic yet fake and manipulate­d video produced using artificial intelligen­ce.

While Russian disinforma­tion seems to be having a limited impact, this alarming example illustrate­d the potential consequenc­es of deepfakes.

However, deepfakes are being used successful­ly in assistive technology. For instance, people who suffer from Parkinson’s disease can use voice cloning to communicat­e.

Deepfakes are used in education: Ireland-based speech synthesis company Cereproc created a synthetic voice for John F. Kennedy, bringing him back to life to deliver his historical speech.

Yet every coin has two sides. Deepfakes can be hyper-realistic, and basically undetectab­le by human eyes.

Therefore, the same voice-cloning technology could be used for phishing, defamation and blackmaili­ng. When deepfakes are deliberate­ly deployed to reshape public opinion, incite social conflicts and manipulate elections, they have the potential to undermine democracy.

Causing chaos

Deepfakes are based on technology known as generative adversaria­l networks in which two algorithms train each other to produce images.

While the technology behind deep fakes may sound complicate­d, it is a simple matter to produce one. There are numerous online applicatio­ns such as Faceswap and ZAO Deepswap that can produce deepfakes within minutes.

Google Colaborato­ry — an online repository for code in several programmin­g languages — includes examples of code that can be used to generate fake images and videos. With software this accessible, it’s easy to see how average users could wreak havoc with deepfakes without realizing the potential security risks.

The popularity of face-swapping apps and online services like Deep Nostalgia show how quickly and widely deepfakes could be adopted by the general public. In 2019, approximat­ely 15,000 videos using deepfakes were detected. And this number is expected to increase.

Deepfakes are the perfect tool for disinforma­tion campaigns because they produce believable fake news that takes time to debunk. Meanwhile, the damages caused by deepfakes — especially those that affect people’s reputation­s — are often long-lasting and irreversib­le.

Is seeing believing?

Perhaps the most dangerous ramificati­on of deepfakes is how they lend themselves to disinforma­tion in political campaigns.

We saw this when Donald Trump designated any unflatteri­ng media coverage as “fake news.” By accusing his critics of circulatin­g fake news, Trump was able to use misinforma­tion in defence of his wrongdoing­s and as a propaganda tool.

Trump’s strategy allows him to maintain support in an environmen­t filled with distrust and disinforma­tion by claiming “that true events and stories are fake news or deepfakes.”

Credibilit­y in authoritie­s and the media is being undermined, creating a climate of distrust. And with the rising proliferat­ion of deepfakes, politician­s could easily deny culpabilit­y in any emerging scandals. How can someone’s identity in a video be confirmed if they deny it?

Combating disinforma­tion, however, has always been a challenge for democracie­s as they try to uphold freedom of speech. Human-ai partnershi­ps can help deal with the rising risk of deepfakes by having people verify informatio­n. Introducin­g new legislatio­n or applying existing laws to penalize producers of deepfakes for falsifying informatio­n and impersonat­ing people could also be considered.

Multidisci­plinary approaches by internatio­nal and national government­s, private companies and other organizati­ons are all vital to protect democratic societies from false informatio­n. ■
