Provable Multi copy Dynamic Data Possession in Cloud Computing Systems in Python

Most of group vendor store unlimited quantity of their data in cloud with facility of retrieving. Users pay costs for storing data. Most of the users are in collaborative relationship; at that time data sharing and dynamic operation are useful to make robust productive benefits. Uploading the data in multiserver is to avoid the data loss from Hacking and server crash. In this paper, we introduce a brand new method is Map based provable multicopy dynamic data that has the aspects like uses multicopy of data, File security and preventing data corruption. In this paper, there are three polynomial algorithms for protecting the data - Keygen, Copygen and Taggen. AES algorithm is used for data security. The authorized user to seamlessly entry the file copies saved through the CSP.
