If anything can be a deepfake, perhaps nothing can be trusted - and politicians can take advantage of the so called "Liars' dividend" by dismissing real media as fake.
In satire, deepfakes have already had a controversial impact, targeting politicians, business leaders, and celebrities. Meanwhile, convincing deepfake audio and video have the potential to create a new wave of fraud where faces, voices and bodies can be stolen.
These malicious uses of deepfake technology started out targeting celebrities and people in the public eye, but have become a mainstream challenge for cyber security professionals and ordinary individuals whose images have been used without their consent.
Deepfakes can be used to defame or discredit people - but on the flip side, the cry of ‘deepfake’ could undermine trust in the use of video evidence in the justice system.
What can we do to protect citizens from synthetic media’s malicious uses? And might there be some positive applications for deepfakes in politics?
