A Report About Lie Detector App – very soon app might tell if you lie or not

Very soon, your phone might be able to tell if you are lying or telling the truth. There is  new machine algorithm wants to tap into the digital interactions that reveal when you are bluffing.

Researchers have been finding some ways in which they can turn your phone into a lie detector instrument.

There is a new machine learning algorithm which has been built by computer scientists at the University of Copenhagen which can detect honesty and dishonesty by analyzing the way you swipe or tap a smartphone.

The research is based on the assumption that dishonesty interactions always take longer and involve more hand movement than honesty interaction.

Veritaps (algorithm) flashes a green check mark when truthful statements are entered into a smartphone and mark an uncertain information with a red mark. The app used for experiment is not made available to the public but it runs on Android Phones.

According to Aske Mottelson ( Aske Mottelson is one of the the paper’s authors) “the algorithm’s ability to detect lies is comparable to that of a polygraph. However, it has its limit and shouldn’t be used in courtrooms or other high-stats environment.

There have been some effort made by the humans in the past at creating a device that can detect if somebody is bluffing. Prominent among these efforts is the discovery of Polygraph in 1921, but Polygraph was attacked with a lot of criticisms over its accuracy and reliability.

There is a video camera called Toronto-based NuraLogix which is similar to the one found in your laptop and phone. It can be used to capture the changes in blood flow  in somebody’s face.

There is another technology called Transdermal Optical Imaging which applies machine learning algorithm and can also detect things such as heart rate and blood pressure.

According to Kang Lee( The company Chief Science Officer) “People cannot control these physiological responses, which makes it easier to tell when they’re lying.” Lee said further, “Machine learning and deep learning allow us to learn about patterns of lying versus truth telling in a much better way. ‘That’s the game-changer.‘ ”

How can my phone tell whether i’m lying?

Now here is the method adopted by the researchers behind Veritaps. They conducted three studies to measure how dishonesty can affect the interaction of a user by using a mobile phone. Their findings revealed that liars always pause before they respond.

In one of their studies, they asked the participants to either tell lie or tell the truth concerning the shown on the screen of their phones. Result? The liar took much longer on the average to respond.

In another study, a person is required to receive money and had to split it with the other person with the option to lie about the amount collected. In conclusion, people generally took more time before entering the amount to give away.

When the final study was conducted, Participants were told to play a mobile dice game. The players were not motivated to lie but were rewarded according to their reported scores by making it profitable for them to do as such. The researchers discovered that the entries which are truth in nature were tapped closer to the center of the screen and with more pressure while the  dishonest players were found to use more hand movement than the honest players.

 

Mottelson said, “It’s easy to forsee how this can be used in non optimal ways. What we suggest is that it doesn’t report on lie classification, but instead it reports on truths, because that means that you can verify an interaction.”

However, smart phones may soon be able to revealed all our lies with this new development.
