Secure data sharing in multi-clouds

Security is the main concern in the cloud computing environment. The usage of the cloud computing in increasing gradually, where the security is still lagging. Traditionally, use of single cloud in cloud computing environment leads to security issues, malicious users, and also untrusted users. The recent research proved that Multi cloud computing provides all the services in a single architecture by combining many clouds. This research aims in providing the reliable source of dependency on multi clouds. The main purpose of this paper is to use multi-clouds for data security and reduce data risks for an efficient and reliable data accessibility. Different techniques are used to implement the multi cloud computing, which lacks in the providing efficiency, data security and privacy, low cost. The leverage of security in multi-clouds is enhanced through application of Data Sharing Algorithm.
