In today's information age, what should we do to avoid information leakage?

We must first know where our information will appear, so we should consciously avoid exposing these local information to others next time.

First of all, all kinds of documents in life, such as tickets, air tickets and train tickets, are registered in real-name registration system and have some information on them, so these documents need to be protected and destroyed in time if they are not needed;

Secondly, there are some free wifi in public places. When we connect, we sometimes log on to the website to verify the mobile phone number, which is easy for hackers to access and then get the user's information.

There are also some social accounts, and now you have to fill in personal information, and there is a real-name registration system, so don't fill in such information if it is not required.

Some data on the mobile phone should be cleaned up when it is time to clean up, so as to avoid that the next person who uses the mobile phone will see his own information after the mobile phone is lost or replaced;

The data on the computer, we should delete some sensitive personal information before changing the computer for others to use;

Remember to clean up the information on the courier, and remember to tear off or clean up the information on the courier when throwing garbage.

In fact, in many small places, private information is easy to be exposed. The above are all data information that we can actively process, but it is inevitable that someone will ask us in life.

For example, when renting a house or doing business, you will leave your mobile phone number, and these mobile phone numbers are generally bought by other similar institutions, and then you will call us.

Often after you buy a house, you will receive many calls from decoration companies and loans. Behind this is actually an industrial chain, and the phone numbers are all enjoyed by them. This is inevitable, only when you try to leave your mobile phone, don't leave your usual mobile phone.

Secondly, for some questionnaires, you are required to leave your phone number at the end. Try not to leave a number or landline.
