<abstract xmlns="http://www.w3.org/1999/xhtml"><p> Personal identification is particularly important in information security. There are numerous advantages of using electroencephalogram (EEG) signals for personal identification, such as uniqueness and anti-deceptiveness.

In this paper, we propose a method for cross-dataset personal identification based on a brain network of EEG signals.

Empirical results of this paper show that the average identification accuracy of each data set was higher than 0.95 and the best one achieved was 0.99, indicating a promising application in personal identification.</p></abstract>
