6ES7 318-3EL00-0AB0 随着移动互联、物联网等新兴技术浪潮的到来,传统的一些对人的认证识别方式已经无法满足社会发展需求。通过计算机与光学、声学、生物传感器和生物统计学原理 等高科技手段密切结合,利用人体固有的生理特性,如指纹、脸象、虹膜等进行个人身份的鉴定,成为大势所趋。
目前来看,识别方式*简便、*实用、***,发展*好的就是“指纹识别”方式。**来看,指纹识别占整个生物识别市场的将近60%的市场份额。
我们能看到*常见的就是指纹打卡、指纹门禁等,不过移动互联网的到来,包括信息安全、移动支付等大量需求生物识别认证,指纹识别已经成为了主流智能设别厂商和消费者能够快速接受的方式。
半导体指纹传感器占市场主流
在智能应用市场爆发之前,指纹识别主要应用于考勤、门禁、锁具等市场,其采用的传感器类型和现在也完全不同。
指纹识别传感器的技术已经经历了几代演进。目前主流的有光学传感器、半导体传感器及超声波传感器三种。光学指纹传感器是*早规模商用的指纹识别传感器,广泛应用于门禁、箱锁具等市场,成本较低但体积较大。
半导体指纹传感器在近两年取得了*炸式发展,基本占据了智能*域全部市场。已成为指纹识别市场的*对主流。
从**市场来看,这一趋势仍将继续。2015年*2021年间,智能用指纹识别传感器市场将持续保持40%的复合年成长率(CAGR),并在2021年以前达到20亿颗的年出货量。
iPhone激发了指纹传感器在智能上的大量应用
苹果公司(http://www.maoyihang.com/company/)于2013年发布了iPhone 5s,从而推动指纹传感器的大量应用。此后几年,指纹传感器在消费类市场中的出货量呈现出不可思议的增长。起初,指纹传感器用于解锁和信息保护。然而现在,指纹传感器越来越多地应用于在线识别和移动支付等安全功能。
