Artificial Intelligence (AI)

Artificial intelligence is intelligence that machines demonstrate, as opposed to the natural intelligence displayed by human or animals.

Voice biometrics security Bhusan Chettri
Voice Biometrics Security

Voice authentication is a biometrics technique of speaker recognition which measure the distinctions in different voices to uniquely identify and authenticate real user.

Voice anti-spoofing

Anti-spoofing is a technique that identify or detects recorded, computer generated, and computer modified voice, including deepfakes and voice cloning by fraudsters.

Ambient intelligence Bhusan Chettri
Ambient intelligence

Ambient intelligence explains the ability of a computer or machine to AI system that detects and reacts to human presence. Common Examples about the usage of this technique is Siri & Alexa.

Machine learning Bhusan Chettri
Machine learning (ML)

Machine learning (ML) is a field of computer science which focuses on the use of data and algorithms for accuracy in artificial intelligence.

It was a pleasure working with Bhusan, He is a very energetic & Intelligent personalty. 

Daniëlle

Very Helpful for understanding Spoofing Attack and how
it can be prevented. understand what makes replay spoofing detection
difficult in the context. How mobile phones authentication systems are
at most risk for this. Good Job Bhusan Chettri Ji!
