The biggest advantage of big data
Good aspects, such as epidemic prevention QR code.This QR code includes your 24-hour whereabouts and the whereabouts of the people around you.Once you are diagnosed positive, your close contacts will be detected and effective measures to prevent the virus out of control.That's the power of big data.Another example; fugitives can be targeted and arrested when appearing and using smart devices.That's how scary it is about big data.

The biggest shortage of big data
The biggest drawback of big data is: personal privacy.Personal Privacy is very difficult to protect.Because now the Internet is
everywhere.Personal data is collected as long as people go online.Once the information is collected, privacy issues arise.If this privacy issue is not handled well, it will have terrible results and adverse effects.For example, some time ago, the Zhengzhou flight attendant incident was a disaster caused by big data
In the Internet age, as long as you surf the Internet and use your phone, your information will be exposed every minute, including but not limited to age, gender, region, phone model, phone price range, favorite, Internet time, and so on
Although our personal information has been hidden in this era, the country has also introduced a series of laws and regulations on the protection of personal privacy, which are still being further improved and strengthened.
In the era of big data, it's hard to worry about nondisclosure.We can only restrict those business or machine buyers who obtain personal information according to the corresponding laws and regulations, and let them achieve information security.This is the main direction of the future development.
