A Framework for Data Storage Cloud to Provide Security

This research focuses on making the cloud more secure for sharing data. The need of more storage space to hold all your digital property is solved by the cloud storage. But the question arises that all your personal data is safe over the internet? Passwords can be hacked; data can be decrypted by Cloud Server. So for building users’ trust in the cloud storage we present a model that provides multi-layer encryption.  The cloud has its own certificate store but in our model we present an idea that enables user’s data not to be viewed by Cloud servers but only users and the ones whom they allow access. The users’ can buy the certificates from a company, any third party that is not involved with the Cloud Storage service. Users encrypt the data through their certificates and then share the data on the cloud. The cloud is considered safe and it is the need of the time to have large storage space for your digital property but we present a way to eliminate the threat in cloud computing.
