With the intensification of telecom fraud cases, the state has also stepped up its crackdown. Although the case has been solved, everyone has begun to think about the leakage of personal data, which is also worrying. So, how is everyone's personal information leaked and how to prevent it? Now, let me share my experience with you.

If the WiFi automatic connection function is selected in the network settings of the smart phone, it will automatically connect to WiFi in public places. The security protection function of WiFi is relatively weak, and hackers can steal any user name and password on WiFi through some simple devices. So try not to use free WiFi without password in public places. When using WiFi to log in to online banking or Alipay, you can access it through a special APP client. It is best to set the WiFi connection to manual.

Many people will resell old mobile phones when they get new ones. Although you restore the old mobile phone to the "factory default settings" or even format, through technical means, professionals can still restore all the SMS, address book, software and even browsing records in the old mobile phone, and even the payment account and credit card information may be restored. So for mobile phones with personal account information, try to avoid resale. If you really want to sell it, you must do a thorough cleaning before reselling it.

Now some people interact with acquaintances through Weibo, QQ space, post bar, etc. , sometimes unconsciously say or mark the other party's name, position, work unit and other real information. This will cause the hidden danger of personal information disclosure. Therefore, in social networks such as Weibo and QQ Space, it is necessary to avoid exposing or labeling real identity information as much as possible. Be careful when taking pictures in your circle of friends.

When surfing the internet, you will often encounter various activities such as filling out questionnaires, playing test games, shopping lottery, or applying for free mailing materials and handling membership cards. Generally, you need to fill in personal information such as detailed contact information and home address. Therefore, before participating in such activities, you should choose a reputable website to carefully verify the real situation of the other party, and don't fill in it rashly, which will lead to the disclosure of personal information.

Nowadays, many people apply for jobs through online resumes, and personal information in resumes is readily available. Some companies will also ask you to fill out a so-called "personal information form" with your family relationship description, parents' names, personal phone numbers, addresses, graduation schools and even ID numbers. So under normal circumstances, only the necessary information is provided on my resume, so don't fill in my specific information in too much detail.

Express bills, tickets, boarding passes, shopping receipts, business bills for mobile phone cards, water and electricity bills ... all these documents may lead to the disclosure of personal information. Don't leave too many details about the courier address. Useless files can be directly shredded, or personal information such as name, phone number and address can be blacked out and discarded. Take good care of useful documents and don't throw them about!

Banks, telecom operators' business halls, registration for various exams, etc. Many places need to keep copies of their ID cards, and even some typing shops and copy shops use convenience to temporarily store customer information in the copy shop for archiving. So be sure to keep a copy of your ID card, dispose of the unused or invalid ones, and don't throw them away at will.
