  • 第16题:


    Which one of the following statements about iPhone X’s FaceID is false according to this article?( )

    A.It is a whole new technique Apple Inc.applied on iPhone X.
    B.It has started a revolution in computer-vision industry.
    C.It has a problem of revocation.
    D.It has embedded security mechanisms to secure the data on the phone.

    答案:B
    解析:
    细节题。根据第一段第三句Apple claims to have conquered many of the challenges that have prevented the widespread use of facial biometrics.及第二段第一句话Apple’s new technology…可知,人脸识别技术确实是苹果用在iPhone X上的一项全新技术,故A项正确;根据第一段最后一句话But a number of computer-vision researchers say they are skeptical that…可知,苹果的该项技术遭到了计算机视觉研究人员的质疑,其并没有在该领域引起一场(新)革命,文中也确实没有相关说明,故B项说法不符合原文;根据最后一段可知,该技术存在撤销问题,故C项正确,根据最后一段倒数第二句Apple touts its ability to secure data…servers.可知,D项正确。故本题选B。参考译文:你的脸就是智能手机安全的未来。苹果公司上周发布价格高昂的iPhone X时明确表示了这一点。苹果公司声称已经克服了许多阻碍面部生物识别技术广泛应用的挑战。但是很多电脑视觉研究员说,他们怀疑像FaceID这种基于智能手机的系统,是否能在诸如灯光变化或人脸部发生细微变化的情况下还能安全又实用,一天之内解锁十几次或更多。苹果的新技术听起来确实很有前景。苹果公司表示,FaceID通过在一个人的脸上投射超过30 000个红外点,然后使用手机的红外真实深度相机和大功率微芯片来收集和分析结果,从而创建一个人的面部“精确深度图”。用户还被要求在扫描时转动头部,这样手机的机器学习算法就可以从几个角度测量人脸,并创建更详细的三维特征图。一旦图谱创建并存储,苹果电脑就会使用红外光帮助FaceID在黑暗中扫描人脸。与此同时,手机上运行的机器学习算法会跟踪用户外貌的变化——包括眼镜、面部毛发和帽子——因此智能手机面部识别的准确性会随着时间的推移得以提高。尽管近年来面部识别技术有所进步,但我们仍不清楚FaceID能否在不同的外界条件下工作的同时,又能保证苹果手机的安全。例如,三月份三星Galaxy S8的面部识别扫描仪推出时,黑客们很快找到了一种绕过它的方法:他们只是简单地用了一张用户照片就唬住了手机。FaceID使用三维面部特征图可以解决这个问题。但是从历史上看,这种系统在不同的光照条件下,从不同的角度识别人脸仍是一个巨大的挑战。密歇根州立大学计算机科学与工程教授阿伦·罗斯说,苹果公司上周在相对可控的条件下展示了FaceID。“很明显,演示非常有趣,”他说,“但与此同时,也提出了一些非同寻常的要求。”例如,苹果公司的席勒说,随机一人用脸解锁别人手机的几率是百万分之一——比触摸识别安全得多。罗斯说,然而,还不清楚FaceID无法识别机主的频率。当被问及关于席勒的评论的问题时,苹果公司拒绝回应。康奈尔理工大学的计算机科学教授维塔利·施马蒂科夫说:“与所有的生物识别技术一样,FaceID在撤销方面也会有问题。”密码被泄露可以更改,但人的面孔无法更改。苹果吹嘘其苹果手机上具有数据保护能力,声称不会与公司的服务器共享生物特征信息。罗斯说,方法再安全严密,黑客似乎总能找到办法破解。
