What is the purpose of collecting personal information when the BMW 4S shop illegally uses the face recognition system?

Recently, it broke the news that BMW 4S store installed cameras in the store to collect face information, but customers were completely unaware of these cameras, which led many netizens to condemn the practice of BMW 4S store when the incident broke out, and the disclosure of personal information also made many netizens very angry.

Many people don't understand these enterprises. Why do they collect personal information?

First of all, these chain stores generally accept customers from all over the country. At this time, if we use the face recognition camera, we can deeply understand whether customers have entered the store before, and we can also get better performance through such data collection. Through these data collection, the camera will automatically tag the face, and at this time, the employees in the store only need to see the tag of the camera to know whether the customer wants to buy it.

Secondly, now is an era of relatively developed information, and personal information represents one's life experience to a certain extent. These personal information can be resold to others through the black market. These people may do some very bad things through these phone numbers or the collected face recognition information, but people who sell personal information do not pay attention to this problem and are still selling personal information to get rich.

Personal information is very important to us. I believe everyone has received calls from various insurance industries. These people know your current situation very well. For example, college students often have postgraduate institutions to call you. If they leave the society, there will be text messages and phone calls such as buying a car and a house. These phone calls sometimes cause great trouble to everyone. At the same time, they will be very afraid that their personal information will be used by bad people in other places.
