【文章內(nèi)容簡介】 The introduction to facial recognition.Chile most human identification technology panies choose to focus on facial recognition, one Chinese startup claims to have developed a much more accurate identification system based on micro features of veins(靜脈)within human hands.Developed by MELUX, AirWave is an incredibly efficient identification system that is said to be a million times more accurate than facial recognition technology. There are only 80 to 280feature points on a face that artificial intelligence can assess when scanning an individual, but AirWave is able to scan more than a million microfeature points in the palm(手掌)of the hand within seconds, making it virtually impossible to cheat. A simple scan of the palm over a special sensor is all that39。s required to get an ultraaccurate identification in real time.The AirWave fullhandvein technology, based on artificial intelligence, is capable of sensing millions of microfeature characteristic points, from major veins to the smallest organs,with just a single wave of the hand, enabling users to remain in motion while being identified and authorized, Xie Qinglu, founder and chairman of MELUX, recently told China Daily.The major veins and the smallest organs under skin are individually unique, and they are at the fivemicrometer level and even more plex than road systems in a big city, Xie added.The AirWave technology can identify one hand out of a billion accurately in less than threetenths of a second.Right now, China39。s cashless society relies on facial recognition, QR codes and password systems to authorize(投權(quán))mobile considers current approaches to be either exploitable by weberime experts, or unfriendly to senior citizens. Privacy concerns are also wellfounded, especially where facial recognition is concerned, so AirWave is considered much more efficient and secure, easy to use by anyone, and less attacked.Published in 2018, AirWave technology has been making waves in China over the past year, and is already being in several cafeterias and government public service areas in South China39。s Guangdong Province.28.

Unless you have a serious disease such as diabetes,you probably haven39。t ever tested your own blood. But in the future, that might change.The pany Cor already sells a system for home blood testing. You stick your arm using a supposedly painless cartridge. Then you stick the cartridge into a device that looks like the base for an electric toothbrush. A few minutes later, an app on your phone offers you updated information, including your current health status and tips on what to eat and how to 39。s true that blood provides abundant information about a person39。s health. Specific tests can reveal if a person is infected with a disease or at risk for a variety of problems. But most people don39。t test their own blood often. Healthy young adults get blood tests approximately every five years. Cor and similar panies are trying to change the situation. They think people deserve access to more information about their health.But not everyone is convinced.The bestcase scenario(情景)here is that you lose much money and then you39。re
