The periphery of a Taylor Swift concert is as thought out as the show she presents on stage. Beyond the traditional merchandise stands, there are often dedicated selfie-staging points and staff distributing light-up bracelets. When Swift performed at the Los Angeles Rose Bowl venue, fans could watch rehearsal clips at a special kiosk.
泰勒·斯威夫特音乐会的周边区域就像她在舞台上的表演一样，是经过深思熟虑的。除了销售周边商品的摊位，通常还安排了专门的自拍点，以及发荧光手环的工作人员。当斯威夫特在洛杉矶玫瑰碗的演出现场表演时，歌迷们可以在一个特别的亭子里观看其排练片段。

What they didn’t know was that a facial recognition camera inside the structure was taking their photographs and cross-referencing the images with a database held in Nashville of hundreds of Swift’s known stalkers, according to a Rolling Stone report.

The use of facial recognition software is rising at public events. In April, Chinese police used the technology to arrest a man attending a Jacky Cheung concert in Nanchang. The 31-year-old, who was wanted for “economic crimes”, was located among a crowd of 60,000 concert goers.
公共场合人脸识别软件的使用正呈上升趋势。去年 4 月，中国警方利用该技术逮捕了一名在南昌参加张学友演唱会的男子。今年 31 岁的他因“经济犯罪”而被通缉，他当时混在 6 万个演唱会观众之中。

have (been) done 和 having (been) done 的区别
have done 和 have been done 都表示的是现在完成时，having done 和 having been done 都是动词 ing 形式的完成形式，在句子中作状语，起到补充说明的作用。
要注意的是，having 所接的动词表伴随，且发生的时间在主句中谓语动词发生的时间之前。比如：Having driven all day, we were so tired. 这个例子中，“we were so tired”是句子主干，“Having driven all day”是伴随动作，且 drive 的动作发生在 be tired 之前。 而文中的句子为：“Mohammed Jaffar was sentenced to six months in jail and five years’ probation, having been convicted for burglary after he appeared at Swift’s New York home five times in two months.” “他将入狱 6 个月，缓刑期 5 年”发生在后，是句子主干部分；“因在两个月内五次出现在斯威夫特在纽约的家中而被判入室盗窃罪”发生在前，作为一个伴随状语。
以上读懂之后，我们顺便看看 having done 和 having been done 的区别，前者 having done 表示的是主动，后者 having been done 表示的是被动。文中是“被判有入室盗窃罪”，所以用被动。再举个例子对比一下：
- Having driven all day, we were so tired. 因为是“我们主动开了一天的车”，所以要用主动；
- Having been criticized today, he was so sad. 因为是”他被批评”，所以要用被动。
