Literature Survey on Secure Data Storage on Cloud

Cloud computing can be defined as a new style of computing in which dynamically scalable and often virtualized resources are provided as services over the internet. With cloud computing technology, users use a variety of devices, including PCs, laptops, smart phones, and PDAs to access programs, storage, and application development platforms over the Internet, via services offered by cloud computing providers. Cloud Computing moves the application software and databases to the large data centers, where the management of the data and services may not be fully trustworthy. We categorize the existing research according to the cloud reference architecture orchestration, resource control, physical resource, and cloud service management layers, in addition to reviewing the existing developments in privacy-preserving sensitive data approaches in cloud computing such as privacy threat modeling and privacy enhancing protocols and solutions. Our main aim to propose more reliable, decentralized light weight technique for which provides more efficient data security in cloud computing.
