As we all know, the underlying logic of the "big data communication travel card" is very simple, mainly relying on the positioning function of the mobile phone to determine the owner's own action trajectory by positioning the mobile phone.
Everyone is familiar with the positioning function of mobile phones. Everyone should have had the experience of being authorized by various apps in mobile phones. The "big data communication travel card" is not exactly the same as these apps. Not only positioning, but more importantly big data analysis.
"Big Data Communication Travel Card" is based on communication big data, with unified interfaces for three major operators and four positioning methods. In order to prevent people from hiding their whereabouts and causing unnecessary epidemic prevention safety accidents, these four methods are as follows:
1. Base station positioning
In our life, base stations are everywhere. By 2020, the total number of mobile communication base stations in China will reach 93 1 10,000. Each of these base stations has its own fixed coverage area. Like a transparent network, they cover 9.6 million square kilometers of land in China. When we start to move with our mobile phones, the base stations for signal access will also change constantly, so that we can determine the mobile phones.
2. Wireless network positioning
A wireless network, also known as WIFI, is like a scaled-down base station. Each router has a unique MAC address. When the mobile phone is connected successfully, the location is naturally exposed.
3. Satellite positioning
The accuracy of this positioning method is very high, and the error is generally less than15m. Since 20 18, most Android phones have used Beidou satellite navigation system, and other mobile phone systems generally use GPS positioning system, but they all belong to satellite positioning. In daily life, we often use it to realize navigation, positioning and other functions. Everyone's mobile phone roaming query relies on satellite positioning function.
4. Mobile phone built-in positioning
There is an IMEI identification code in the mobile phone, which is mainly composed of IMEI, MEID or S/N. This identification code has no influence on whether the mobile phone is turned on or not and whether there is a card in the card slot.
When the phone is turned off without a card, it will still be recognized by the base station. After recognition, the base station can extract and analyze big data, so that you can easily find the location of the mobile phone. If you want to know the IMEI identification code in the mobile phone, you can check it in the settings in the mobile phone or click the dial key on the mobile phone, and enter *#06# in the dial interface to get the IMEI code of the mobile phone.
In these positioning methods, most of them still need to be powered on and networked, such as base station positioning, WIFI positioning and satellite positioning, but some of them don't need to be powered on or plugged in, just need to bring your mobile phone, such as the IMEI identification code built into the mobile phone.
Therefore, if you don't want to be positioned by the "big data communication travel card", the simplest and rudest way is not to bring a mobile phone. Of course, you can also remove the mobile phone battery and SIM card at the same time, which should avoid being located.
However, in this era, mobile phones have become a part of our daily life. Most people feel uneasy when they leave their mobile phones, but most of the smart phones we use now are all-in-one machines, and the batteries are not detachable, so neither of these two methods is feasible, but we are ordinary people who do our duty, so we don't have to care too much about being taken away by the "big data communication travel card".
The answer is yes, and similar cases have been reported. June 5438 +2022 10, when a student was going to take a taxi from Nanjing University of Technology to Nanjing Railway Station, he suddenly found that his mobile phone was missing. After the alarm, the police immediately tracked the running track of the mobile phone according to the positioning function of the classmate's mobile phone, and finally found the mobile phone.
On June 6th, 20021,a student went to Fan Shi, Xinzhou to take the college entrance examination. After the mobile phone was lost, the police also took surveillance, found the face and clothes information of the old man who found the mobile phone at the first time, and compared the identity of the old man with the train information through big data, and finally recovered the mobile phone.
These mobile phones can finally be retrieved, not only thanks to the serious responsibility of the police, but more importantly, with the help of the positioning function of mobile phones and the analysis function of big data.
The Information and Communication Administration of the Ministry of Industry and Information Technology also made it clear at the press conference that "Big Data Communication travel itinerary" will not collect the owner's ID number, home address and other information, and will strictly enforce the privacy protection requirements. So far, in the analysis of communication big data, there has been no incident of personal information leakage.
However, we have to admit one thing. Big data is a double-edged sword. We can all be producers, users, beneficiaries and victims of big data. It can provide you with the right information, products and services before you speak, but it may also use your preferences to kill big data. For ordinary people, these problems mainly depend on the attention of the state and the improvement of laws.
