With the development of science and technology now, the frequency of people's use of the Internet is more and more high, in the enjoyment of the convenience of the Internet at the same time, the Internet will also threaten the problem of people's information security. In society, the topic of personal privacy leakage has received more and more attention. In this era of big data, people are always worried about their privacy being leaked. When using computers, cell phones and other network devices, people will enter their personal information, so people will worry about the leakage. So can Eye in the Sky check personal information? And can a social worker's library find out personal information?

First of all, the Eye in the Sky system is a large data repository connected through the Internet, and when people's personal information is stored in this database, the Eye in the Sky system can be used to find everyone's personal information in this large database. However, most of the SkyEye is used to check the relevant business information, focusing on the relevant information of the company's legal person.

The social worker library is also a product of the way big data is stored, and when hackers use the analysis of big data in conjunction with it, they can look up personal information. The social worker library can be used to look up personal information through an individual's cell phone number. For example, the household name, QQ number address, including previously used passwords.

So both SkyEye and Social Worker's Library can look up people's personal information. The only thing is that the SkyEye system searches for information through a large database of directly stored information. And the social worker database is through hackers to carry out attacks on the large database in order to find personal information.
