National laws have made it clear that buying and selling personal information is an illegal act, but many institutions in society are still carrying out hidden operations. Our personal information may flow out through various channels, and it is still common to leak it out from schools.

My uncle's younger brother took the senior high school entrance examination this year. The children didn't like studying very much, so their grades were not very good. So he planned to find a technical secondary school to learn some skills. During the period before and after the senior high school entrance examination, he received calls from various technical secondary schools, but we didn't consult any institutions before. So where did these educational institutions get our information by calling? Obviously, it was from the school. As for who leaked our information from the school, there is really no way to find it.

each of us has been exposed to all kinds of sales calls, and now our names will be clearly known in the sales calls. At most, I can receive more than a dozen such calls a day, and I don't know from which channel my information flowed out and who I sold it to. Because we need to fill in the phone number frequently to register various software and websites, and now we need SMS verification for registration, we can't write a fake number at all. This has also led to our personal information being mastered by many people. Sometimes everyone's information will even be resold many times, becoming a tool for others to promote products, and even leaving loopholes for fraud agencies. It is understood that a lot of detailed personal data can be sold for dozens of pieces on the Internet, and we really have no privacy at all.

Every school will gather a large number of students, and the information of these students will be mastered by the school. However, there are so many people who have access to this information in the school that they lack the necessary confidentiality measures, and many schools will openly disclose the information of students in the name of cooperation.

For example, the school handed over students' information to the bank, set up a credit card for each student, and the information of 3, college students was leaked collectively. If we can find out the facts and confirm that there is an interest transaction, this can be sentenced through criminal law.

banks and educational institutions attach great importance to students' information collection, because in these institutions, they have very clear data requirements for business personnel, and they have to complete a certain amount of data if they want to get paid. Banks, on the other hand, determine their performance based on the number of cards opened, so many business personnel will do whatever it takes to obtain data in order to fulfill their performance requirements. However, it is still difficult to obtain a large amount of personal information by personal efforts, so school resources will become the focus of these people's attention. With the benefit-driven, some people will naturally ignore the legal provisions and sell their personal information. If this collective disclosure of personal information is not too obvious, this kind of thing is really difficult to be discovered, and it is difficult to completely cure it simply by relying on legal supervision.
