Security Approach for Multi-Cloud Data Storage

Abstract

In many organizations, transformation of information and storage of sensitive data has highest priority. Client data should be kept secret as well as inaccessible from all other unauthorized hacks . To maintain the security of the user data, cloud computing environment has practiced. The cloud computing is a cost-effective, service availability, flexible and on demand service delivery platform for providing business through the internet . However, as the security of a single cloud is concerned, it fails to provide a strong protection layer against the malicious attacks. So, there is always a risk of data unavailability in system failure. A movement towards of “multi clouds” or “multiple clouds‟ or “cloud-of-clouds” has emerged currently using Shamir’s Secret Sharing Algorithm . Here, the implementation of Shamir’s secret sharing algorithm is performed to authenticate a unique user and to access a particular file from the cloud storage.
