Research On Citizens' Personal Network Information Security Under The Background Of Big Data

Rapid progress in technology,big data networks are widely used.Big data technology has improved the efficiency of workand communication.The information technology has entered a new era.The rapid progress of information technology,the coverage of network systems,people because of the use of the Internet in the face of lifestyle and work environment have undergone disruptive changes,the development of technology has been more than 20 years,China due to the use of the Internet generated by electronic information and data is huge,cnnic 2020 released a report shows that China's Internet users have 940 million,penetration rate of 67% and the data processing capabilities have been essentially improved.But risks coexist,such as the illegal trafficking,theft,and use of personal information for improper gains have also become challenges in the process of social development.Large internet companies like BAT gathering the great massof Chinese Internet users' information.The novel coronavirus pneumonia epidemic situation is the special period of the world in 2020.The senior expert Li Lanjuan of the health protection committee mentioned that the big data technology played a great role in China's fight against the epidemic situation.It provided the staff's examination and management through analyzing the epidemic trend,searching and locating the infected persons and close contacts,and city and community personnel flow management.Timely and effective information.Scanning codes in and out of communities,epidemic prevention,control and investigation systems are all known and accepted by people using big data network information for management,but also the management of network data security has high risk.The relevant contact information is made public(name,address,mobile phone number)of the confirmed personnel,the continuous occurrence of fraud cases by using the network information of citizens' personal purchase of masks,and the continuous increase of criminal data through the use of personal network information of citizens has had a serious negative impact on the security,stability and rights of the country,society,and individuals.The era of big data has brought an important impact on personal information security.Through sorting out specific problems in reality,combing out the source of the problems from various perspectives.If government want to improve the security of citizens' personal information,we need many efforts.From the perspectives ofindividuals,society,and the national perspective,the article from the above aspects to give practical value of the proposal.The article systematically demonstrates the subject from five aspects,the first aspect is to sort out the relevant articles around the topic,to build the cornerstone of the theory for the later content,and to define the main concepts clearly;the second part combines my country's Special circumstances,explain the essential relationship between citizens' personal information security and big data,and the reflected characteristics;the third part,based on the analysis of the government's network security information supervision,this paper sorts out the hidden dangers and risks in the government's supervision of citizens' network information security.In order to further explain the harm of network information security,the fourth part of the thesis extracts the main ways of incidents by sorting out the typical individual network information security is a common problem in the world.In the process of analyzing typical cases,the common problems are sorted out,the thesis analyzes the specific problems and causes of citizens' personal network information security.Finally,combining the different characteristics of the individual level,the enterprise level,and the government level,a more operable countermeasure to protect personal network information is proposed.
