Biometric scanner technology - Market Assessment

生物识别技术提供了一种个人和方便的方式来保护我们的身份和数据的安全。有许多生物识别身份验证方法得到了广泛的研究，从指纹扫描仪到视网膜传感器再到面部识别软件。在这些方法中，指纹识别可能是最广为人知的，而且已经通过各种方法实现，无论是基于红外、多摄像机系统还是声波。然而，所有这些都被证明容易被略读和身份盗窃。在大多数此类案件中，犯罪分子在接触上述指纹扫描仪时，可以创造出与用户手指或手相同的3D打印手指或手。一种使用无线电波识别各种个人的方法已经开发出来。在该系统中，紧凑型收发信机具有多个发射和接收天线。发送器(S)发送一系列信号，这些信号被用户(在我们的演示案例中是手)身体附近的部分吸收、反射和散射，结果信号在接收器(S)天线上被检测到。对接收到的信号应用不同的信号处理算法以创建丰富的特征数据集。使用机器学习模型对得到的数据集进行分类，这被证明有助于高精度地识别一组个人。这项技术作为一种独立的或辅助的生物识别工具具有很好的应用前景。与现有技术相比，该技术承诺具有更高的安全性和对身份盗窃和黑客企图的免疫力。潜在应用-边境控制/机场。-军事安全系统。-选民登记和身份识别。

Biometrics offer a personal and convenient way of keeping our identities and our data secure. There are manybiometric authentication methods that have been extensively studied, ranging from fingerprint scanners toretina sensors to facial recognition software. Of these, fingerprinting is likely the most well-known, and hasbeen achieved through a wide variety of methods, whether based on infrared, multiple camera systems, or onacoustic waves. However, all of these have been shown to be prone to skimming and identity theft. In most ofsuch cases, criminals can create a 3D printed finger or hand with identical features to those of a user finger orhand when exposed to the aforementioned fingerprint scanners.A method of using wireless waves to identify various individuals has been developed. In this system, thecompact transceiver has several transmit and receiver antennas. The transmitter(s) send a sequence of signalswhich are absorbed, reflected, and scattered from a nearby part of the body of a user (a hand in our demo case)and the resulting signal is detected at a receiver(s) antenna. Different signal processing algorithms are appliedto the received signals to create a rich feature dataset. The resulting dataset is classified using machine learningmodels, which are shown to facilitate identifying a group of individuals with high accuracy.This technology has promising applications as an independent or an auxiliary tool for biometric authentication.The technology promises to be of a much higher level of security and immunity against identity thefts andhacking attempts than existing technologies.Potential Applications- Border Control/Airports.- Military Security Systems.- Voter registration and identification.
