This document presents the development of an EEG-based biometric authentication and security system. It involves acquiring EEG signals from the scalp, preprocessing the raw signals by filtering and artifact removal, extracting features from the signals in the time, frequency and time-frequency domains, classifying the features using support vector machines or neural networks, and authenticating individuals based on their unique EEG patterns. The system aims to provide a more secure alternative to conventional authentication methods like passwords, RFID, and facial recognition.
