How does the probe box collect nearby mobile phone numbers and personal information? How do ordinary people guard against it?

The mac number of the mobile phone mentioned in the news report is converted into imei, and then matched with the mobile phone number, and finally information such as marriage, love and age is obtained. In fact, there is still a missing link, that is, using technology and algorithms to infer your gender, age, hobbies and hobbies through browsing, installing and accessing your imei records, which is different from stealing information directly.

But in the era of big data, a certain amount of data can improve the accuracy of the algorithm's speculation about your attributes and hobbies, which means that all your information has been mastered by others.

Personally, the real gray link of wifi probe is that imei matches the mobile phone number, because the mobile phone number can reach the user directly through the call, which is more private. Moreover, the browsing, installation and access of users of equipment records will not be prohibited, which is the most basic principle of Internet advertising. Foreign Google, facebook and domestic bat advertising business are all based on this principle. If it doesn't work, the shopping app can't recommend similar products that you have browsed, the travel app can't recommend travel products that suit you according to your location, and the consulting app can't recommend articles that you are interested in, because all online recommendations are based on your browsing and other behaviors.

Therefore, in the Internet age, everyone is naked and cannot be avoided.
