When using the browser camera quietly open, in the e-commerce site to place an order after shopping always receive sales calls, browse a certain early childhood education website information will frequently receive a variety of early childhood education organization sales calls, if you have encountered the same situation, then your information has been leaked.

Personal data information leakage rises year by year

At the 2018 Internet of China Conference, the China Institute of Information and Communications Technology (CIICT) released the White Paper on Big Data Security (2018).

The whitepaper shows that big data has become a key target of cyberattacks due to its immense value and centralized storage and management model, and that the problems of ransom attacks and data leakage targeting big data are becoming increasingly serious, with major data security incidents occurring frequently.

Gemalto's 2017 Data Leakage Level Index Report shows that the total number of data leaks globally in the first half of 2017 was 1.9 billion, exceeding the total number of the whole year of 2016 (1.4 billion), and increasing by more than 160% compared to the second half of 2016, and the number of data leaks globally has shown a year-on-year upward trend from 2013 to 2017.

Data breaches in China occur from time to time. According to Shodan, as of February 3, 2017, 15,046 MangoDB databases in China were exposed to the public network with serious security issues.

And previously, the media has reported incidents such as cameras being secretly turned on while using a browser, and online e-commerce platforms being hacked and leading to leaks of user information.

The China Academy of Information and Communications Technology (CAICT) believes that big data has had a profound impact on the economic operation mechanism, social lifestyle and national governance capacity.

But we should also see that big data is a double-edged sword, and the influence and destructive power of the results of big data analysis and prediction on the social security system may be unpredictable.

In the future, intelligent decision-making based on big data will play a more important role in economic operation, social life and national governance, and big data may have a more far-reaching impact on all aspects of the country's "11 kinds of security".

Therefore, it is necessary to examine the issue of big data security from the perspective of "big security", and stand at the height of the overall security concept of the country, break the traditional technology-heavy security protection mode of thinking, and establish an all-around big data security system that involves multiple perspectives of economy, law, and technology.

China University of Political Science and Law, China Intellectual Property Research Center, a special researcher, IT and intellectual property rights lawyer Zhao Zhanzhao believes that enterprises have the responsibility to protect user data security. The network security law and other relevant regulations point out that companies need to fulfill their obligations to ensure information security after collecting users' information, whether it's technology or other management measures. "For example, such things as crashing the library, not necessarily the responsibility of the network service provider, it depends on whether the network service provider is at fault for the leakage of the user's information, for example, whether it is not the use of basic security measures to prevent."
