AI Lie Detector

This AI can tell if you're lying... while User speaks, This AI analyze the users facial expression and voice tone then gives the output as whether he/she is telling truth or not/suspicious.

Inspiration

Detecting Truth in Real-World Scenarios Limitations of Traditional Polygraph Systems Human Behavior & Psychological Cues Rise of Artificial Intelligence in Daily Life Real-Time Facial Analysis Technology Need for Smart Security Systems AI in Crime Investigation & Fraud Detection Combining Computer Vision and Machine Learning Automation of Human Judgment Future of Intelligent Surveillance Systems

What it does

The system observes a person while they answer questions and then:

👉 Analyzes their behavior 👉 Finds patterns linked to lying 👉 Gives a result: Truth or Lie

How we built it
