A method for identifying the distinct wave pattern which the brain produces when a person is exposed to a known stimulus is called a brain fingerprint. Compared to other ways, this technique is far safer and can be utilized for authentication. On the other hand, authentication plays a crucial role in our everyday lives and is utilized in a variety of settings, including banks, offices, schools, institutions, home automation, and automobile automation, among others. Nowadays, a variety of techniques, such as fingerprint and retinal scanning, are typically used to establish identification. Verifying the identity of the individual is the primary goal of all these methods of identification. Compared to all of these verification techniques, brain wave patterns offer numerous benefits. The usage of brain waves as a password generation works quite well for very confidential objects. The most widely used biometric identification techniques comprise voice, face, and fingerprint recognition. Everything could be a fake. We know that the electroencephalogram (EEG) can be used as a biometric detection technique and that every individual has a unique brainwave pattern. This study investigates the application of brain waves as a biometric password authentication technique.
