Biometrics can also be brushed with new tricks "brain fingerprints"?
The nature of biometrics has made it the new darling of the 21st century as soon as it emerges, and technologies such as face, sound or fingerprints are becoming more and more important. With the continuous development of technology, biometrics has now played with new tricks.
The safety and convenience of biometrics have made it the new favorite of the 21st century. Some mobile phones turn on “printing fingerprintsâ€, and the company calls “brushing facesâ€, which are all biometric technologies. Biometrics can even be used to deal with financial fraud and security threats. For example, Barclays has introduced the “TouchID†fingerprint scanner, which allows customers to log in to online banking via a fingerprint scanner on their mobile phone.
Recently, Palm Teng Intelligent Technology has developed a palm vein recognition instrument, which is a kind of “brushing hand†instrument. Its main core support technology is “palm vein recognition†technology.
It is understood that the "palm vein recognition" technology has a significant advantage, that is, it can be "brushed" without touching the instrument, giving the user a sense of non-compliance in terms of hygiene, and is particularly suitable for use by a non-specific number of people. Not only that, but because of the previous characteristics of living body recognition, internal features and non-contact, it is difficult to forge the user's palm vein features.
Compared with other biometrics, the palm veins are complex and complex, with high recognition accuracy and high safety and stability. When the palm vein is used for identity authentication, the image features of the palm vein are acquired, which is a feature that exists only when the palm is in the living body. In this system, the non-living palm is not able to obtain the characteristics of the vein image, and thus cannot be identified, and thus cannot be faked. In addition, the low cost of palm vein recognition and great compatibility make the “brushing hand†more widely used in life.
Of course, the more research prospects are the brain, and emerging biometrics based on brain brainwave activity do show the potential for fraud prevention.
Many studies have found that each person's "brain fingerprints" (that is, the brain's response to certain words or tasks) are different because each person's brain has a different way of thinking. Studies have shown that the brain recognizes a person from 102 people with an accuracy rate of more than 98%, which is very close to the accuracy of fingerprint recognition (99.8% accuracy).
Recently, functional magnetic resonance imaging (fMRI) technology has confirmed this. A study of MRI data linking humans found that people are doing something specific about brain activity, such as relaxing, listening to stories, calculating mathematics, looking at emotional expressions, or imagining a part of the body. When moved, these people were identified with an accuracy rate of 99%.
Is "brain fingerprinting" really feasible? It doesn't seem to be simple. The cost and difficulty of using MRI (which must stay in the scanner for a considerable amount of time) means that it is clearly not suitable for everyday biological identification. For this reason, researchers turned to electroencephalography (EEG). But it is also very troublesome. Who wants to wear a gel electrode on the head to use the computer? Therefore, this technology has always been used only in science fiction.
However, in view of its strong security, "brain fingerprinting" technology is undoubtedly of great research value. As technology continues to evolve, we may soon see biometric applications based on brain fingerprints, especially as part of a multi-factor recognition system that enhances authentication. Therefore, when you see brainwave headphones in the mail from the bank, don't be surprised to go. This is the era of artificial intelligence in our lives.
