EEG-Based Random Number Generators

In this paper, we propose a new method that transforms electroencephalogram (EEG) signal and its wave bands into sequences of bits that can be used as a random number generator. The proposed method would be particularly useful to generate true random numbers or seeds for pseudo-random number generators. Our experiments were conducted on the EEG Alcoholism dataset and we tested the randomness using the statistical Test Suite recommended by the National Institute of Standard and Technology (NIST) for investigating the quality of random number generators, especially in cryptography application. Our experimental results show that the average success rate is \(99.02\%\) for the gamma band.
