A multi-cloud approach for secure data storage on smart device

Using a mobile device to store sensitive data is not recommended, because of the high possibility of losing or thieving these data; although, neither using single cloud as a storage service is not proper solution for number of reasons; for instance, the data could be captured while uploaded to the cloud, and the data could be stolen from the cloud via using stolen ID. In this paper, we propose a solution that aims to offer a secure data storage for mobile cloud computing users based on multi-clouds scheme. The proposed solution will take the advantages of multi-clouds, data cryptography, and data compression to secure the distributed data; by splitting the data into segments, encrypting the segments, compressing the segments, distributing the segments via multi-clouds while keeping one segment on the mobile device memory; which will prevent extracting the data if the distributed segments have been phished.
