Brainwave Based Authentication System : Research Issues and Challenges

Despite extensive research conducted in authentication system, security issues are still a challenging task. The most common authentication mechanism is Username and Password. Due to its lack of efficacy, it has been proved as weak method for authentication. In the recent years, Biometric authentication methods have been receiving increasing attention. The design of the biometric system requires human biological physical characteristics such as fingerprints, ear, face, and plamprint etc. The general problems of these characteristics are its easy acquisition process therefore the numbers of attack vectors are associated with them. To reduce the chances of attacks in authentication system research has taken the direction to brainwaves based authentication system which is an alternative method. The objective of this article is to summarize and presents a comprehensive review of well known methods used in brainwave authentication system and identify the research topics and application which are at forefront of this exciting and challenging field.
