Convergent Dispersal: Toward Storage-Efficient Security in a Cloud-of-Clouds

In the existing system, if the owner wants to share the data from one user to another user there are chances for some security issues to be present. The data which is being transferred from user to user can be hacked. To overcome the security issues, we propose a system where the data transformation is done with high security. If the uploaded data is stored directly then there are chances for data leak. We provide a solution where the uploaded data is getting split into four parts and each key will be generated for the four parts while storing it in the database and it will be encrypted. If the user wants the file access which is uploaded by the owner then the user can send the request.
