Development of a novel EEG wave controlled security system

Abstract

The need for good security systems in banking, e-commerce and other applications is ever increasing. The proposed project makes the security system more robust and less prone to attacks. Brain Computer Interface (BCI) is used in order to obtain the password from the user by using their brain waves. This paper describes the current trend in BCI technologies and then the Hardware implementation of the proposed solution has been described. The Electro-Encephalogram (EEG) waves are obtained with the help of active dry electrodes and processed using signal conditioning circuits. These EEG signals are then interpreted to obtain the thought pattern of the user to match them to the stored password in the system. Finally a Transmitter-Receiver model has been used with a lock interface system is used to indicate the opening or closing of the lock.
