面部识别技术正越来越多地被应用于各个领域。现在，一种被称为面部检测的技术正在进入一个新的领域：广告业务。面部识别技术是用来识别特定个体的，而面部检测系统的目的是检测个人的存在，并试图预测有关个人的一些信息。在美国，目前这种系统正在一些商店进行测试。

Facial recognition technology is increasingly being used today in many places in the United States and overseas. Such systems use machine⁃learning tools to scan faces in an attempt to recognize particular individuals.

Many police agencies across the world have long used facial recognition technology to search for and help catch criminals. The technology has also been used at some US airports to help confirm the identity of passengers. It is also used to unlock phones or other electronic devices， and in some cases， even cars. Some robots use facial recognition to recognize the people they are communicating with.

Now， a similar technology—known as facial detection—is entering a new field： the business of advertising. Facial recognition technology is meant to identify a specific individual. Facial detection systems aim to detect the presence of a person and try to predict some facts about him or her. In the United States， such systems are currently being tested in a small number of stores.

Businesses use cameras set up inside the stores or public area. The cameras scan the faces of individuals and predict their age and sex. Some systems are also designed to judge a persons emotions. That information can then be used to target people with real⁃time advertisements on video screens during their visit to the store.

One facial detection system， developed by a company called Mood Media， aims to judge a persons “happiness” or “fear” level. Businesses could use such information to get real⁃time reactions from people as they look at products or video ads in the store. Such a system could also be used as part of a companys efforts to test the popularity of specific products.

Another company， Cineplex Digital Media， showed off a camera?powered system designed for use in retail businesses， on the street or at bus stops. The company says its product can detect things like whether someone is wearing eyeglasses or has facial hair. That information could then be used to target those people with ads for new glasses or shaving equipment.

Some privacy groups have criticized the use of such facial detection systems while supporters of the technology say it could improve the buyers experience by drawing attention to products they might like or by offering them special deals.
