Users aren’t able to effectively obtain control of the storage position of their own data in the public cloud,which considerably threatens the security of users’ data.In order to protect the users’ core data in cloud computing,we proposed that we could protect users’ data with the hybrid cloud architecture,thus we designed the Users’ Core Data Protection Model Based on Cloud Computing,UCDPMBCC.This model divides users’ data into two parts,the core data and the general data.The core data would be stored in private cloud which users can control,while the general data would be stored in the public cloud from the service provider after being filtered.This effectively solves the protection and security problem of users’ core data.By taking advantage of the existing internet security products,we constructed the Users’ Core Data Protection Model Based on Cloud Computing according to the model together with the algorithm for data sorting designed by us.The effectiveness of the model has been testified with actual use and it explores a new approach to provide the users with the protection for their core data. 云计算 核心数据 安全模型 保护系统 cloud computing core data security model protection system 10.14188/j.1671-8836.2013.02.010 TP309 贵州省自然科学基金资助项目（黔科合J字LKS[2009]12号） 2013-02-01 2021-04-01 2 59
