Cloud computing is a web based computing which presents different customers an opportunity to store their data in the cloud. For cloud storage, privacy and security are the burning issues. Storing their data in cloud may not be fully trustworthy. When users store their data on the cloud then there may be a risk of losing the data, or sometimes data may be modified or updated.
