In this research our aim was to supplement some deficiencies in the current research with EEG
devices in the context of user authentication with our small contribution. We stated that the current
study has the lack of applicability outside of laboratory conditions, with less expensive
equipment and we set the goal to create a new authentication method that will be applicable to
typical an EEG device currently available on the market. From the results of the research, it is
evident that such inexpensive devices have little potential for a system such as pass-thought (this
initial research included six test subjects with specific mental tasks), but are good at resolving
the meaning of alpha and beta waves to infer about the mental state of users. Specifically, in
our case the device output was accurate measurement of concentration and relaxation of
users, so we applied those signal values as an additional parameter for the enhancement of
passwords.
