Trends in technology from traditional Internet giants such as Alibaba, Baidu, Tencent, and Jingdong, to unicorns in areas such as Face++ and Shang Tang Technology, and to startup teams that just entered, facial recognition is not only a patent of a large company. The field of face recognition on the server side and the mobile side presents a contending trend.
Today, we are all accustomed to various biometric technologies to protect the security of computers or other devices. Commonly used biometrics include facial recognition, retina recognition, and fingerprinting, and we can use them to unlock computers and cell phones, or make payment transfers, or even any desired functionality. Now scientists from the University of Buffalo have invented a new type of biometric technology that uses our heart to determine our identity and to achieve safety verification.
This technique uses a low-power Doppler radar to measure the user's heart. This measurement method ensures that no other form of elemental intervention is involved and that it can be attempted to be identified using a computer. The team scientist of the technology stated that this is a safe and effective alternative to passwords and a representative biometric identification.
Researchers said that this technology can also be used for smart phones and airport security. The author of the study, Wenyao Xu, said that people do not have to worry about the strength and potential side effects of this Doppler Leda, and its radiation is lower than our common Wi-Fi signal. The first heart scan takes 8 seconds.
After completing the first scan, the monitor can continue to measure the heart. The research team has conducted a three-year study of the system and said that no two people have exactly the same heart. The advantage of this system is that it adopts a passive non-contact recognition method.
In fact, this technology can continuously monitor users and block other people. This means that when leaving the device, there is no need to specifically shut down or log off the device. Researchers are currently working on gradually miniaturizing the system and trying to install it on a computer keyboard. The research team stated that the system can identify targets 30 meters away in the presence of obstacles.
The original title face recognition operator can now verify the identity of the heart
