Research On Personal User Privacy Information Protection In Cloud Storage Environment

With the development of information technology and human civilization,the amount of data generated is explosive growth.Traditional data storage and analysis methods can not meet the existing needs.Cloud storage,with its convenient,intelligent and low-cost characteristics,has rapidly become an important way of user information storage and management.In the process of using cloud storage,users store a large number of personal privacy information on cloud storage platform,thus losing their absolute control over information,causing users to worry about privacy and security,together with technical defects,management loopholes,relative imperfection of laws and laws,and the general weakness of citizens' privacy and security awareness,and other factors,the leakage of privacy information.Events occur frequently,illegal and criminal activities of stealing user information are prohibited repeatedly,which brings serious harm to users,thus seriously restricting the development of cloud storage.Therefore,it is particularly important to protect personal user privacy information in cloud storage and effectively avoid the risk of privacy leakage.This paper mainly studies the privacy information protection of personal users in cloud storage environment.Through reading the relevant literature at home and abroad,the connotation,classification and risk of personal user privacy information in cloud storage environment are clarified.Based on rational behavior theory,protective behavior theory and trust theory,the user privacy information protection model in cloud storage environment is constructed,and the model is tested by designing corresponding questionnaires and analyzing retrieved data.According to the conclusion of empirical research,a comprehensive information security system integrating multiple stakeholders and user privacy is established from six aspects: law and regulation system,organizational management system,security technology system,security education system and complaint supervision system,in order to improve the security of user privacy information.
