Face recognition systems are often not accurately identified due to subtle changes in external features. According to the official website of the University of Buffalo on the 25th, the team of Chinese scientist Xu Wenzhao developed a new computer security system that can identify the heart geometry, replace passwords and other biometric systems for computers and smartphones. And identification of airport security.
The previously developed cardiac identification system mainly uses an electrode to measure an electrocardiogram, so it needs to be in direct contact with the human body, which is inconvenient to use. Dr. Xu’s new system, which has been developed over the past three years, does not require direct contact with the human body. It uses radar long-distance scanning to analyze the geometric shape of the heart and the geometrical characteristics of the heart and the heart fluctuations. Relevant research papers have been submitted to the 23rd International Conference on Mobile Computing and Communications, which will be held next month.
Everyone saves private information on their own computers, and previously only set up accounts and passwords to prevent others from using their own computers. It is cumbersome to enter passwords multiple times a day. The heart recognition system monitors the master's heart through low-level Doppler radar. The first scan takes 8 seconds, after which the computer remembers the owner's heart, the "bad guys" who don't want to log in to the computer to steal information. ", will be shut down after being recognized by the system. Dr. Xu said that no two people will have the exact same heart shape, and unless they have a serious heart disease, each person's heart shape will remain the same, and the new system identification is extremely accurate.
The radar signal strength of the system is weaker than the currently used Wi-Fi, so it does not pose a threat to human health. The new system has a power of only 5 milliwatts and less than 1% of the smartphone's power, which is the same as the Wi-Fi environment we live in every day. Dr. Xu said that they will continue to reduce the size of the system so that it can be installed in a corner of the computer keyboard. In addition to computer security, the new system can also be used for smartphone identification for users, as well as for airport security, for identity checks for passengers up to 30 meters apart.

As a traditional security barrier, the password seems to be becoming more and more "earth". From the face recognition and fingerprint recognition that the public is already familiar with, the iris recognition with a little difficulty, the voiceprint recognition, and the vein recognition that seems to be on the eve of the outbreak... The biometrics industry has been very lively in recent years. Now, it has appeared again. Imaginative "heart recognition." However, while admiring the progress of science and technology, we must also see how safe it is to be biometric. Human biological data is so special that it can cause permanent damage if it is stolen. Therefore, the protection of biological information must be more strict and advanced than the protection of traditional accounts.
