Abstract
Electroencephalography (EEG) brain signals have been used in a number of pattern recognition studies. Due to the high degree of uniqueness and inherent security, EEG-based brain signals have been considered as a potential pattern for biometrics, especially for continuous authentication. Although previous research has been conducted with different visual stimuli, music stimuli for brain signal authentication are rarely considered. One unresolved question is whether these brain signals that change over time will affect the authentication results. An EEG database with 16 volunteers has been employed in the analysis to observe any changes in brain wave patterns as well as changes in authentication rates. The data were regularly collected over a period of four months while exposed to three different genres of music.
