The researchers say their findings could be a stepping stone in the fight against deepfakes.
“The fact that the brain can detect deepfakes means that current deepfakes are flawed,” said Associate Professor Carlson. “If we can learn how the brain spots deepfakes, we could use that information to create algorithms to flag potential deepfakes on digital platforms like Facebook and Twitter.”
Further into the future, they foresee that technology, based on their and similar studies, could be created to alert people to deep scams in real time. For example, security personnel may wear EEG-enabled headsets that could alert them that they may be facing a deepfake.
Electroencephalography (EEG), a test that reveals activity in the surface layer of the brain, was used in the researchers’ study.
Associate Professor Carlson said: “EEG-enabled headsets could have been useful in preventing recent cases of bank robbery and corporate fraud in Dubai and the UK, where scammers used cloned voice technology to steal tens of millions of dollars. In these cases, finance staff thought they heard the voice of a trusted customer or associate and were tricked into transferring funds. »
