Biometrics are identified by people's unique physical characteristics or behaviors. These technologies are rapidly evolving. This article will introduce five biometric technologies that may replace passwords in the future. The whole process of high-energy sci-fi challenges your brain! Fingerprint recognition is based on the texture of the human fingerprint, details and other information for the operation or identification by the operator. Thanks to modern electronic integrated manufacturing technology and fast and reliable algorithm research, it has begun to enter our daily life and become the current The most in-depth research, the most widely used, and the most mature technology in biometrics. Finger vein recognition is a kind of vein recognition. Firstly, the finger vein distribution map is obtained by the finger vein recognition instrument. The characteristic value is extracted from the finger vein distribution map according to the special comparison algorithm, and the finger vein is obtained by the CCD camera through the near-infrared light irradiation. The image stores the digital image of the finger vein in a computer system and stores the feature values. Face recognition is based on a person's facial features, an input face image or a video stream. First, it is judged whether or not there is a human face, and if there is a human face, the position and size of each face and the positional information of each main facial organ are further given. Based on this information, the identity features contained in each face are further extracted and compared with known faces to identify the identity of each face. Palm vein recognition is another mature technology in this field. When using the palm vein for identity authentication, it acquires the image features of the palm vein, which is the characteristic of the palm when it is alive. 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. Iris recognition technology is now widely recognized. For more than a decade, the US military has been using iris recognition technology. The ID card system and passport system around the world also use the human eye as a channel of identification. Iris recognition technology is more accurate, but sometimes there are recognition obstacles when the device performs retinal scanning.
