Deepfake videos could be commonplace and found across the media and online platforms within six months, according to a leading expert.
The idea of the videos is to look completely real and show people doing things they never did.
These are created by complex computing and artificial intelligence and have caused outrage recently.

The video that kicked off the concern last month was a doctored video of Nancy Pelosi (pictured), the speaker of the US House of Representatives. It had simply been slowed down to about 75 per cent to make her appear drunk, or slurring her words
Dr Hao Li, a computer scientist at the University of Southern California, revealed the videos could soon be commonplace.
Deepfakes combine and superimpose existing images and videos onto source images or videos using a machine learning technique known as generative adversarial network.
They are used to produce or alter video content so that it presents something that didn't, in fact, occur.
Most fake video can be easily spotted, but Dr Li believes the obvious giveaways will soon disappear.

Deepfakes are so named because they utilize deep learning, a form of artificial intelligence, to create fake videos.
They are made by feeding a computer an algorithm, or set of instructions, as
