EEG-based biometrics for person identification and continuous authentication
In this chapter, we will provide an overview of EEG biometrics and discuss some of the salient research issues that need to be addressed for making EEG biometric an effective tool for providing information security. We introduce brain signals, especially EEG signals and its analysis methods, before we discuss brainwave biometrics from four aspects, namely the criteria, the elicitation protocols, the feature extraction methods and the classification algorithms. The chapter is then concluded with discussions on how to integrate EEG biometrics with other biometric modalities for continuous authentication, followed by open research questions on the design of EEG-based biometric systems.
