Be careful! 9 ways to accidentally expose your information

Recently, the media reported that nearly 80% of Internet users' mobile phone numbers in China have been leaked, and more than 50% of Internet users have been affected by spam text messages, phone scams, and phone charges. A quick search on the Internet revealed that interacting on Weibo, participating in "rewarded questionnaires", applying for free mailing materials, and even applying for membership cards may inadvertently "betray" yourself or your friends.

1. Various online documents leak personal information

The logistics note on the express packaging contains the name, telephone number, address and other information of the online shopper. In addition to the information leakage caused by netizens inadvertently throwing away the express note after receiving the goods, the courier may also sell the recipient's information; after the real-name system is implemented for train tickets, the name, ID card and other information of the ticket purchaser will be printed on the ticket. Many netizens will discard their train tickets after taking the train. Once criminals pick them up, they will use the ticket reader to steal the personal information on the ticket; on the paper statement of credit card purchases, information such as name, bank card number, consumption record, etc. is recorded. Discarding it at will will also cause private information leakage.

2. Inadvertently betraying friends or being betrayed by friends during online chats

Although netizens use nicknames on Weibo, it is not ruled out that they call each other by their first names in commenting and interacting, which inadvertently leaks real personal information. For example, when writing a diary or posting a photo on QQ space, some information such as name, position, unit, etc. may appear in the comments or forwarding of friends.

3. Social platform QQ Mail accidentally "betrays" itself

Nowadays, there are numerous online social platforms. However, in various forums and social networks, you need to fill in personal information before you can chat and interact. For example, many netizens use QQ mailbox as the first choice for registration mailbox, and it often appears in the reply posts of major forums and communities. Usually, QQ mailbox directly displays QQ number, and criminals can then obtain personal information from QQ information, space and other channels.

4. All kinds of online shopping, virtual communities, and social network accounts are full of dangers

While e-commerce platforms bring convenience to people's shopping, they also contain risks. Online shopping requires registering some account information such as forums, communities, Weibo or QQ, which will more or less leak personal information. Therefore, do not fill in your real information on the Internet. You can write some fixed information to use online to minimize the exposure of your true identity.

5. Street surveys, promotions, and lucky draws

On the street, people sometimes encounter merchants inviting them to participate in "questionnaires", shopping sweepstakes, or apply for free mailing of information or membership cards. They generally require passers-by to fill in detailed contact information and home addresses, etc. However, this can easily send your information to others' doorsteps!

6. Your online resume accidentally reveals your true identity

Nowadays, most people look for jobs by submitting resumes online, and the personal information in the resume is complete, which may be resold by illegal elements at a very low price. Therefore, in general, do not fill in too much personal information in the resume, such as home address, ID number, etc.

7. Registration and photocopying information can be easily stolen

When registering for various exams, attending online classes, etc., you often need to register your personal information. Even some typing shops and copy shops take advantage of the convenience and file customer information and then sell it.

8. Abuse of ID card copies

An ID card is required for opening a bank account, registering a mobile phone, applying for a membership card, or redeeming points at a supermarket. When providing a copy, be sure to write "For such and such use by such and such unit only, invalid for other use." In addition, pay attention to the copying process and destroy any excess copies.

9. Online “personalized services” can also easily leak privacy

Many personalized services require personal information. For example, in LBS (location-based services), many businesses cooperate with social networking sites to determine the user's location through wireless networks, and then push products or services. What is even more frightening is that users are "monitored" in real time, which opens the door to fraud, kidnapping and extortion.
