Area of Science:

  • Biometrics and Neuroscience
  • Artificial Intelligence in Healthcare

Background:

  • Conventional biometric systems face security challenges.
  • Electroencephalography (EEG) offers a promising alternative for identification.
  • Developing accurate and efficient EEG-based identification is crucial.

Purpose of the Study:

  • To propose a novel EEG-based identification system.
  • To evaluate the system's performance using emotional EEG data.
  • To investigate the influence of emotions and time intervals on identification accuracy.

Main Methods:

  • Utilized different entropy measures combined with a continuous convolution neural network (CNN).
  • Experimentally evaluated the proposed DE-CNN model on emotional EEG datasets.
  • Analyzed the impact of various emotions, time intervals, and frequency bands (0-75 Hz, 15-32 Hz) on performance.

Main Results:

  • The proposed DE-CNN system achieved an average accuracy of 99.7%.
  • Negative and neutral emotional states showed better robustness compared to positive emotions.
  • The 0-75 Hz band demonstrated superior robustness over single bands, while the 15-32 Hz band led to overfitting.

Conclusions:

  • The novel EEG identification system demonstrates high accuracy and rapid training capabilities.
  • Emotional states significantly impact identification performance, with negative/neutral moods being more robust.
  • Specific frequency bands and time intervals influence system robustness and accuracy, highlighting the need for careful selection.
