Privacy and Trust Management in Cloud Computing

Cloud computing is a technology that uses the internet and central remote servers to maintain data and applications. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. This technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth. In the last few years, cloud computing has grown from being a promising business concept to one of the fastest growing segments of the IT industry. But as more and more information on individuals and companies is placed in the cloud, concerns are beginning to grow about just how safe an environment it is. The purpose of the paper is to focus on various privacy and trust issues in Cloud Computing with the aim to suggest solutions on them. To address the privacy and trust challenges in Cloud Computing, a Client-based Privacy Manager is proposed in this paper. We proposed Client-based Privacy Manager that allows establishing privacy and trust in cloud environment. The design is totally user-centric. Most of the operations involved in granting data accesses are done at the client-side. This minimizes the load over the Cloud Service Provider.
