Question

    Large gatherings such as weddings and conferences can be socially overwhelming. Pressure to learn people's names only adds to the stress. A new facial-recognition app could come to the rescue, but privacy experts recommend proceeding with caution.

The app, called Social Recall, connects names with faces via smartphone cameras and facial recognition, potentially avoiding the need for formal introductions. “It breaks down these social barriers we all have when meeting somebody," says Barry Sandrew, whose start-up, also called Social Recall, created the app and tested it at an event attended by about 1,000 people.

After receiving an invitation to download Social Recall from an event organizer, the user is asked to take two selfies and sign in via social media. At the event, the app is active within a previously defined geographical area. When a user points his or her phone camera at an attendee's face, the app identifies the individual, displays the person’s name, and links to his or her social media profile. To protect privacy, it recognizes only those who have agreed to participate. And the app’s creators say it automatically deletes users’ data after an event.

Ann Cavoukian, a privacy expert who runs the Privacy by Design Center of Excellence praises the app’s creators for these protective measures. She cautions, however, that when people choose to share their personal information with the app, they should know that “there may be unintended consequences down the road with that information being used in another context that might come back to bite you”.

The start-up has also developed a version of the app for individuals who suffer from prosopagnosia, or “face blindness”, a condition that prevents people from recognizing individuals they have met. To use this app, a person first acquires an image of someone's face, from either the smartphone’s camera or a photograph, and then tags it with a name. When the camera spots that same face in real life, the previously entered information is displayed. The collected data are stored only on a user's phone, according to the team behind the app.

【解析】

这是一篇说明文。文章主要讲了像婚礼和会议这样的大型聚会在社交方面会让人应接不暇。记住别人名字的压力只会增加压力。一款新的面部识别应用程序可能会发挥作用，但隐私专家建议谨慎行事。

1.推理判断题。根据第二段The app, called Social Recall, connects names with faces via smartphone cameras and facial recognition, potentially avoiding the need for formal introductions.可知，这款名为Social Recall的应用通过智能手机摄像头和面部识别功能，将名字和面孔联系起来，从而避免了正式介绍的必要。由此推断出，Social Recall是被用于识别人的。故选A。

2.主旨大意题。根据第三段After receiving an invitation to download Social Recall from an event organizer, the user is asked to take two selfies and sign in via social media. At the event, the app is active within a previously defined geographical area. When a user points his or her phone camera at an attendee's face, the app identifies the individual, displays the person’s name, and links to his or her social media profile. To protect privacy, it recognizes only those who have agreed to participate. And the app’s creators say it automatically deletes users’ data after an event.可知，在收到活动组织者发出的Social Recall的邀请后，用户被要求拍两张自拍照，然后通过社交媒体登录。在活动中，该应用程序在之前定义的地理区域内处于活动状态。当用户将自己的手机摄像头对准出席者的脸时，该应用就会识别这个人，显示这个人的名字，并链接到他或她的社交媒体资料。为了保护隐私，它只承认那些同意参与的人。该应用程序的开发者表示，它会在事件发生后自动删除用户的数据。由此可知，第三段主要讲了这款应用程序是如何工作的。故选D。

3.细节理解题。根据最后一段To use this app, a person first acquires an image of someone's face, from either the smartphone’s camera or a photograph, and then tags it with a name. When the camera spots that same face in real life, the previously entered information is displayed.可知，要使用这款应用，用户首先要从智能手机的摄像头或照片中获取某人的面部图像，然后给它加上一个名字。当摄像机在现实生活中发现相同的人脸时，就会显示之前输入的信息。由此可知，Social Recall可以帮助面容失认症患者，当它看到一张存储的脸时，就会显示出这个人的信息。故选B。

4.推理判断题。根据倒数第二段She cautions, however, that when people choose to share their personal information with the app, they should know that “there may be unintended consequences down the road with that information being used in another context that might come back to bite you”.可知，然而，她警告称，当人们选择与应用程序共享个人信息时，他们应该知道，“这些信息被用于另一种情况，可能会产生意想不到的后果，可能会反过来伤害你”。由此推断出，Social Recall可能会把人们的隐私置于危险之中。故选C。
