How does big data track people's trajectory?

Big data is to get your personal information through a lot of data analysis, such as the mobile phone APP you use, your habits, the bus you often take, and so on. Let me give you an example here.

In 2020, data exploded exponentially, and everyone was generating data every day. The mobile application you use has been collecting your data. When you browse or buy goods in the shopping software, the shopping software will recommend the goods you are interested in, the goods you want to buy or the goods you have browsed, and the collected goods will be discounted or reduced.

By analyzing your data, the software can classify and mark your portrait, so everyone's software is the same, but the home page is definitely different. If you don't believe me, you can ask someone next to you to open the shopping software. You can compare and see if your two software home page recommendations are the same. Through big data analysis, you can know where you work, and through time analysis, you can know what you do, whether you are a civil servant or a factory worker. You can judge whether you have a car by the means of transportation you take to work. People with cars will receive sales calls from insurance companies, loan companies and so on. Because big data knows what you need, what it will recommend to you, and the data you generate will be collected and processed by the software and fed back to the software homepage. This is a complete mechanism.

Big data analysis makes us have no privacy. Web crawler crawls personal information from the Internet every day, such as name, phone number, ID number, etc. The horror of data analysis is frightening. Are you shocked when a stranger tells you your personal information?

Big data will only roughly locate your location according to the positioning software. Locating a person is very simple, and you can be located through base stations, wireless networks, mobile apps, etc. And you can also locate by a photo and a picture. This is by no means alarmist. It's true. Through a photo shared by a star Weibo, someone successfully analyzed her home address, which floor she lives in, which house and where the photo was taken.

If you don't like your personal opinion, please don't spray it. If there are any shortcomings, please add them.
