A Study on the Impact of Alcoholism on EEG-based Cryptographic Key Generation Systems

摘要

Alcoholism is one of the brain disorders that involves in electroencephalogram (EEG) signals and have impact on EEG-based systems. However, this issue has not been investigated. In this paper, we propose an EEG-based cryptographic key generation system using EEG signals and present experiments performed on two groups of subjects, alcoholic and non-alcoholic groups in the Alcoholism database. This EEG-based cryptographic key generation system is based on an assumption that EEG signal is quasi-stationary if the time window is sufficiently short. With this assumption, stable EEG features are extracted to generate cryptographic keys. The impact of alcoholism on performance of the system is analysed based on our experimental results.
