The user information of Shentong Express has been sold. How to ensure the security of user information?

Express companies sell express user information, and everyone's user information is very important. Each of us should protect our personal information, but we can't stop the courier from selling user information, because we gave the information to the courier company, which is our trust in the courier company. I didn't expect the courier company to sell user information, which would have a great impact on the courier company and make many users lose trust in the courier company. Therefore, the courier company should strictly investigate who leaked the customer's information and should be severely punished. Because this is still a very important reputation issue for express delivery. Personal information such as the courier should be destroyed in time after we receive the courier, and the information on the courier should not be thrown into the trash can. Some people directly dismantle the courier and sell the courier box without destroying the information on it. This is very incorrect. If you want to sell the courier information on the courier box, you must remember to destroy it to prevent our information from leaking. We think that a message may have no effect on us. Everyone thinks that the information on the courier is not particularly important, but it is not. Many harassing calls we receive are from people who buy and sell our information, so we often receive some harassing calls, so we should protect our personal information. However, if the courier sells information, sometimes he can use legal weapons to protect his legitimate rights and interests. After all, everyone's personal information is still very important, and we should all protect our personal information. Sometimes we will reveal our personal information without paying attention, and sometimes it will have an impact on our property security, so everyone should be very careful to protect their personal information and prevent it from being stolen by others.
