Brain-Based Biometric Authentication 

Security plays a crucial role in our fast progressing digitalized world. Nowadays, human biometrics is considered the best security authentication method. Brain signal is another biometric, which recently is in concern of many researchers for authentication purposes. There are some challenges for any EEG authentication method; user-friendliness, collectability, privacy, uniqueness, and permanency or stability of the method through time. According to the studies, the stability of the brain pattern is one of the most important challenges in EEG-based authentication techniques. 

We applied two different brain patterns for authorization and authentication process using EEG signal; Picturizing pattern and deep breath pattern were used to improve security, stability through time regardless of brain situation. Therefore, users can authenticate themselves with visualizing a specific picture in their minds or using deep breath as a security pattern. The results showed that human brain signal can be used as a new biometric authentication, however the methods need to be improved according to the weakness of the brainwaves to acquire and the complications of the human brain in different situations. 

We aims to facilitate research endeavor into human biometrics authentications, healthcare, and IoT using EEG-based devices. more researches are in progress according to the mentioned subject to improve the use of human brain in different aspects in industry.
