PRESERVING PRIVACY & MAINTAINING SECURITY FOR SHARED DATA OVER PUBLIC CLOUD: A SURVEY

Computer Engineering, Cloud Computing

Currently, outsourcing of data to remote cloud is increasing day by day, People are outsourcing their data at Cloud Service Provider (CSP) who are offering vast amount of storage space with low cost which is minimizing the maintenance and burden of local data storage but once data goes into cloud user lose control over their data which brings new security risk. Data storage cost, access restriction and maintaining the integrity of data is a major concern in cloud security. Many organizations do not trust cloud providers to store their confidential data in public cloud storage because of security threats. The solution to the problem is given by different researchers in their work. However, the work in this regard has not achieved all security aspects correctly. The solution to the problem is given by different researchers in their work. However, the work in this regard has not achieved all security aspects correctly. To improve the correctness and performance of data security on the cloud while transferring the file is discussed in detail. While processing users request different attributes are checked for the processing of data. Each state is strictly defined with the attributes over the access.
