How to protect my personal information?

First of all, all your documents will not be lent out. Now it is also a certificate society. If a child is not born, he must apply for a birth certificate, and if he is born, he must apply for a birth certificate. Later ID cards, student ID cards, graduation certificates, work permits, old-age insurance certificates and other documents will accompany us all our lives, but these documents often contain our important information. They are often stolen by others if they are not properly protected. Either relatives and friends borrow files for some illegal purpose, which often leads to information leakage, and this leakage sometimes has serious consequences, so please protect all personal files.

Second, don't leave your personal phone number and real name casually. Nowadays, in order to promote sales, some shopping malls and supermarkets often give customers small gifts, sign their names and leave personal information such as telephone numbers, which are sometimes collected by unscrupulous people and sold to others several times. Therefore, it is absolutely necessary to leave personal information because of petty gain. You can sign a fake name or leave a fake phone number. After all, this gift signing activity is not important, and there is no need to leave your real name.

Third, scan the code to receive gifts. This kind of activity is similar to signing and leaving a phone number, but it is more harmful. Because the code scanning software we commonly use now is WeChat or Alipay, and both WeChat and Alipay have personal funds, we don't know what the second microcode we scan means when scanning the code. It may be software that steals personal information, or it may be software that steals the password of WeChat or Alipay account, so that we can't get small gifts because of small losses, which puts our funds at risk.

Fourth, collect the courier's signature. The development of express delivery industry facilitates life, but express delivery must leave personal delivery address and contact information. This makes it easier for criminals to collect personal information. A few years ago, there were cases in which courier companies bought and sold tens of millions of personal information. We can leave our aliases or phone numbers when receiving the express delivery, but we should leave the names of our relatives and friends, so as not to delay the delivery and cause serious disclosure of personal information.

There are still many things to pay attention to, and we need to pay more attention to them. We should not covet petty advantages and cause great losses.
