C. Noorjahan, Huda Noordean · 2017
Nowadays Cloud Computing became an inevitable thing in human's life. Both individual users and companies seek help of cloud for storing their data. When storing the data in the cloud user will have a fear about whether their data safe or not in cloud. So integrity of the data stored in the cloud is serious issue. To check the integrity of the data we propose a scheme that uses a trusted Third Party Auditor (TPA), who can verify the integrity of the data on demand. In the proposed system TPA does verification job for the user and also for Cloud Storage Server (CSS). So TPA helps users to find out the original data without any online burden to users and helps the CSS to replace the corrupted data with the original data.
