This is AI based perfect lie detector

If you are good at lying, you should be careful from now on. Because Europe based company iBorderCtrl has introduced an AI Project that specializes in Lie detection.

Is it necessary to detect lies?

  •  An average child starts lying from the age of 2 and 3.
  • An average person lies 2 to 3 times in 10 minutes when meeting a new person.
  • Men lie 6 times a day and Women lie 3 times a day.
  • An average person hears 200 lies a day.
  • People can detect 1 out of 2 lies i.e. Liars are smart
I hope the above stats made you understand why lie detection is necessary.

11 September 2001, the day nobody can forget. Al-Qaeda, a terrorist group fooled the border security force and entered the country. They launched attacks on the United States resulting in the death of 3000 people.


Many nations felt that a lie detector would have saved the US. AI lie detector was not developed during that time. Though Polygraph was used during that time, the accuracy of that technology was only 60-65%.

Do you remember?

When you were a child, you used to lie to your mom. But she finds the truth. Do you know how she does that? One reason is she knows you.


Another reason is she reads your facial expressions and movements to find whether you are lying or not. That’s the principle behind this AI project. Artificial intelligence analyses these things to detect your lies.

  • Facial expressions
  • Words you use
  • Microexpressions
  • Your voice tone

Let’s get back to iBorderCtrl. It is a technology firm who work on border security programs. Their aim is to keep the border (Country border) safe from terrorists. So, a group of researchers have developed an AI system that can detect lies during border entry interview.

If you fail in the interview, you will not be allowed to enter the country.

The AI Lie detector works like this:

To enter into European countries, you are supposed to attend an interview conducted by their security force. This was carried by a human before. But things are changed now. Instead of a human, a computer will conduct the interview.

The AI interviewer looks like this


A webcam is connected to the system and you have to answer some basic questions asked by AI interviewer.

Here are the leaked questions:

  1. What is your surname?
  2. What is your citizenship?
  3. What is the purpose of your trip? and much more questions

You need to answer the above questions with verbal answers (speak). You will be given a QR code at the end of the interview. A border security guard will scan the QR code to get all your details. The AI policeman gives you a score out of 100.


If your score is less, you will be questioned by the security forces. If you are suspicious, you will not be allowed to enter the country. However, your score will not be revealed by border security.


With each day passing, AI technology is moving forward and ahead of us. Already many people are questioning the accuracy of this technology, but the growth of AI can’t be stopped by anyone. Instead of finding faults in the system, it is better to work with AI to develop advanced technology and optimize it to makes our lives easier.

AI lie detector is not accurate. But experts are working to make it accurate to deny the entry of harmful people into the country. Technology should assist humans to make better decisions. Technology should not make decisions for us. AI Lie detector can be used as a tool to find the lies. But human intervention to confirm the AI output is highly needed.
