Killing big data is an irregular phenomenon in the industry. A professor at Fudan University found that the more expensive a mobile phone is, the more expensive it is to take a taxi. Although this phenomenon sounds unreliable, it does exist. Now, due to the development of big data, operators can easily obtain some information of users, including some contact information in mobile phones, and judge the quality of users' mobile phones according to some information. This also leads to different charges according to the quality of mobile phones, which is unbearable. This is an irregular operation in the industry. After further standardization in the future, this phenomenon will gradually decrease and will not become a major trend. It is not allowed in society, and consumers will not be willing to let this phenomenon exist for a long time and become a trend. If this trend spreads in this industry, other industries will be affected sooner or later.

Big data technology has become a standard in modern society. In the development of society, especially after the operation of big data, all kinds of people's information has become the source of people's interests. Nowadays, almost all kinds of apps require certain mobile phone rights before use, which also promotes the birth of a system to provide useless information and prevent their own information from leaking. The big data society has turned people into pieces of code, and the manipulation of computers can easily make early predictions based on a person's behavior habits, temper and personality, code of conduct and even the judgment of what happened. Surprisingly, the accuracy of this prediction is often so high that people are afraid, as if in the era of big data, everyone is transparent and has no privacy. Even a small taxi system, which is very common in daily life, can judge the quality of your mobile phone according to the information. The era of big data also has many benefits. It can recommend suitable products and other consumption patterns to you through the analysis of artificial intelligence, which improves people's life efficiency and provides convenience.

The era of big data needs more norms. The more advanced an era is, the more perfect a civilization is. In order to avoid this phenomenon of different charges according to the information obtained, we should actively regulate and put an end to this illegal use of data to analyze others and ask for their property far above the market price. In the era of big data, we need to better protect people's information and avoid the innocent disclosure of some mobile phone numbers. Some people even make money by selling other people's information. This phenomenon needs to be done.
