Can you hide your lying eyes? New lie detection software says 'not so fast'

Can you hide your lying eyes? New technology claims it can “see” the truth. (KSNV)

They say eyes are the window to the soul and one technology company believes they're also the most efficient way to tell if a person is lying.

A new form of lie-detection claims it can see the truth.

"There are markers in the eyes that are able to accurately determine if an individual is being deceptive," says Neal Harris.

Harris is the Vice President of Converus, the company that created this new technology called "EyeDetect."

It uses only the eyes to determine if a person is lying.

"When a human being is being deceptive, there are these micro-dilations of the pupils. We use a scientific term called 'cognitive load.' It's the extra mental energy that it takes to be deceptive and that mental energy creates additional electric activity in the brain," says Harris.

EyeDetect has been in the works since 2003. Only taking 30-minutes to complete, this new testing technology could be faster and more efficient than the old-school polygraph.

Its creators argue that EyeDetect may have the edge because it isn't influenced by human bias.

"We just don't know what biases people bring with them, so by removing the human element we believe we can make the assessment of credibility far more forensic in nature," says Harris.

Ron Slay is a security consultant who administers polygraph exams. He says in his 40 years of experience, he's seen all forms of deception.

He thinks it takes more than a computer system and answering a few questions to detect a lie.

"You can't automate the human mind," says Slay.

We wanted to put both methods to the test, so I sat down to see which machine would read my lie the best.

First, we put the standard polygraph to the test. Slay asked me two questions that were simple enough to answer honestly.

Before he even finished asking me the third question the machine began to react.

Then we tested EyeDetect. Harris had me write down a number between two and eight and hide it.

I chose the number seven. The examiner told me to lie about my number to the machine, but to tell the truth on all the other questions, as the EyeDetect machine calibrated my eyes and monitored my pupil dilation.

Safe to say that I got caught lying or preparing to lie on both tests.

Slay says it can sometimes be harder to catch the people you want to catch because they have their own truths.

"You find out deep into a polygraph they're not really answering your question at all, they're answering what they perceive to be your question," says Slay.

Slay and Harris agree that both EyeDetect and polygraphs can get it wrong sometimes.

"I think absolutely there will be some false positives and false negatives with EyeDetect as it exists today," says Harris.

Harris says the beauty of computer algorithms is that they get smarter over time.

"I trust computers and algorithms more than a human being," says Slay.

Still, the polygraph remains a powerful detection tool, not likely to be replaced anytime soon.

"I think it's the age-old argument of man versus machine," says Slay.

Big time technology company Apple has taken notice of EyeDetect.

Apple purchased the sensor technology that's used to calibrate and read the eyes.

Does this mean our iPhones could become hand-held lie detectors, catching a liar with just a glance at your phone?

Well, that's up to Apple to decide.

EyeDetect says they hope their new technology will have a positive impact on society and give law enforcement another tool to help achieve justice.
