生物体识别近年来非常流行,取代以往相对容易破解的传统密码识别。当前,最普及的是指纹识别,不过最近NEC开发了耳道识别技术,带来新的选择。NEC公司研发的这款新型识别系统能够通过耳道内声音的共振区分不同的人,也就是说可以将你的耳朵用作密码。该技术利用耳道形状人人不同的原理,达到生物识别的效果,通过声音特征进行判断准确性超过99%。它不需要扫描,而是依靠配备内置麦克风的微型耳机来接收并测算声音。这款生物识别系统辨认声音特征只需大
In recent years, biometrics has become very popular, replacing the traditional password recognition which is relatively easy to crack in the past. Currently, the most popular is fingerprinting, but NEC recently developed its ear canal recognition technology to bring new options. The new recognition system developed by NEC distinguishes between different people through the resonance of the sound in the ear canal, which means you can use your ear as a password. The technology uses the principle of different human ear canal shape to achieve the effect of biometric identification, the accuracy of the sound through the characteristics of more than 99%. Instead of scanning it, it relies on tiny headphones with a built-in microphone to receive and measure sound. This biometric system only needs to recognize the sound features
