With the development of the big data era, the problem of information leakage has become serious, I believe that we have begun to produce more or less awareness of the protection of information security, because If someone else knows our ID card number number and phone number may cause the occurrence of: property risks, information leakage, telephone harassment, the ID card is registered, make fraudulent phone calls and other things.

Information leakage may be taken by others with ID cards and phone numbers to do a variety of membership registration, for a variety of membership cards, or be sold twice. Believe that many people have had the experience of applying for a membership card, in a store to register for a membership card, a little simpler will ask you to leave your phone number and name, a little more formal will ask you to leave your identity card number, if others know your identity card number and cell phone number can do whatever you want.

Many websites may only require the ID number and reserved number to match each other in order to bind successfully,so if the ID number and phone number are known by others, plus the bank card has also been compromised, then the risk of loss of the money in the bank card, through the ID number and the bound cell phone number, which leads to the loss of the property in the bank card.

I don't know if anyone has such an experience, since the online shopping, always receive a lot of spam, and even some did not online shopping, but also will be subjected to a lot of inexplicable text messages, which is the sequelae of the leakage of cell phone numbers. Other people can sell their cell phone numbers to advertisers and some unscrupulous people, who keep sending some commercial advertisements and some fraudulent text messages, affecting the lives of individuals.

And in the early days when network security was not perfect, it was possible to find some people's ID numbers on the Internet, and these people were leaked because of their IDs and were put on the Internet at random, for people who didn't know each other to use to sign up for all kinds of things with no known risk.

This shows that ID numbers and phone numbers, if known by others, can be very risky, may affect your money security, or affect your personal life, so we must regulate our own network life, in order to prevent their own information leakage, resulting in unnecessary trouble.
