A decade of EEG Analysis: Prospects & Challenges in Biometric System

EEG signals have been investigated in medical and entertainment applications for many years. Recently, researchers have investigated EEG signals as a biometric trait for person identification and authentication. EEG biometric system has achieved reasonable accuracy, yet some of the challenges hinder the development of ready to deploy EEG based biometric systems. This paper highlights the emerging challenges of the EEG biometric system. The authors present the interrelationships among identified challenges and review the published articles quantitatively based on publication time and online library.
