Power of Positive and Negative Thoughts Extracted from EEG Signals to Find a Biometric Similarity

The electroencephalogram (EEG) signal is the electrical activity of brain neurons. In this paper, an analysis of the EEG signal is conducted on positive and negative thoughts. Positive thought is defined as the EEG signal that is transmitted when the subject thinks yes in response to a question. Negative thought is defined as the EEG signal that is transmitted when the subject answers no. The EEG signal was recorded using four channels at positions C4, C3, P4 and P3 with a sampling frequency of 256 Hz. In this paper we discuss on the two main areas that are used for identification: the right/left brain symmetric and the other one is to form a matrix for identification of all person. The power of the signals are used to form a matrix for biometric purposes
