Israel develops AI tech to detect lies via facial muscle movements

Israeli researchers have developed a new artificial intelligence (AI) technology to expose lies through movements of facial muscles, Tel Aviv University (TAU) said Wednesday, reported Xinhua.

The new technology may lead to the development of cameras and software able to detect deception in many real-life scenarios, TAU noted.

Using the new technology, the researchers detected lies told by trial participants at a high accuracy of 73 percent, it said.

In their study, published in the journal Brain and Behavior, TAU researchers identified two different groups of liars: those who activate their cheek muscles when they lie, and those who activate their eyebrows.

The study was founded upon a TAU innovation of stickers printed on soft surfaces containing electrodes that monitor and measure the activity of muscles and nerves.

In the future, the electrodes may become redundant, with video software trained to identify lies on the basis of the actual movements of facial muscles, the researchers noted.

It may be useful in detecting lies at banks, airports, police interrogations and online job interviews, using trained high-resolution cameras, they concluded.
