Combining Cryptography with EEG Biometrics

Algorithm 2

Encoding.

Input: EEG channel signal values

 (1) Calculate covariance matrix of EEG channels.

 (2) Calculate -scores of covariance matrix values.

 (3) Normalize -scores.

 (4) Binarize -scores into EEG code using zero value as threshold.

Output: EEG code
