What can be used as a password? From the simplest 8-bit characters, to the fingerprint recognition of the touch screen, to the cool iris recognition, these methods can tell the device who I am. But in the Internet of Things (IoT) era, where a wide variety of wearable devices collect all kinds of information, and keyboards and touch screens are no longer a necessity, how to make devices "identify" our identity and protect us. Privacy security? Over the years, scientists have been looking for new ways to identify themselves, some of which have been traced back to the source – using our brains to tell who I am.
Speaking of it, is there anything more than a unique way of thinking to prove who you are? When we do some thinking activities, such as imagining a graphic or licking a song in our brain, our brain produces unique neuronal electrical signals. The electrical signals of these neurons are unique. Even if one billion people sing the same song in their hearts, they can't find the same brainwave mode. Therefore, it is highly safe to use brain waves as a new biometric method. However, in order to achieve this sci-fi unlocking method, we need to use electroencephalograph (EEG) technology.
In April of this year, psychologists and engineers at Binghamton University in New York said that their use of brain EEG as a biometric has reached a milestone – its accuracy has reached 100%.

Electrode cap with 30 electrodes
Sarah Laszlo, associate professor of psychology at Binghamton University, and Zhanpeng Jin, professor of electrical engineering, led the study. In the experiment, the subject wore a hat with 30 electrodes that were connected to high-quality EEG equipment for scientific research. The 50 subjects wearing the electrode caps watched 500 pictures on the computer screen, each of which showed a time of 1 second. These images stimulate the subject to produce a voltage change in the head, and this is called an event-related potential (ERP). Even if you look at the same picture, different people will generate unused ERP. Therefore, Laszlo assumes that as long as the brain is stimulated to produce enough ERP, it can accurately distinguish the identity of different people. The EEG device connected to the electrode cap transmits the collected EEG information to a software called a classifier, which then determines who you are.
Later, Laszlo found that only 3 electrodes and 27 images were needed to make the identification accuracy 100%. This is a big leap, which means the brain is highly safe as a new biometric technology," Laszlo said.

The hacker used this picture to clone the fingerprint of the German Defense Minister Ursula von Delaine.
Highly safe, this is not a blow. At the moment, if your fingerprint identification data is stolen, you can reset your fingerprint identification. But if your fingerprint itself is stolen, then resetting your fingerprint identification will not work. In 2014, a hacker cloned the fingerprint of the German Defense Minister Ursula von Delane based solely on a high-resolution picture of a hand taken at a public event. But the advantage of using brain brain waves as biometrics is that the brain responds to a sequence based on a particular picture. If the EEG of a picture is "blacked out", you can change another picture or reorder it to create a new one. Biometric password. Hackers can clone your fingerprints based on high-definition images, but he can't clone your brain thinking.
