A Literature Survey on Data Privacy/ Protection Issues and Challenges in Cloud Computing

Cloud computing is a technique to deliver software, storage and processing. It increases system’s capability without changing the existing infrastructure, educating new people or taking license for the softwares. It improves the existing software capabilities and extends the Information Technology resources. In recent years, cloud computing has grown up rapidly and boosted the business concept in IT industry. Despite of all the achievements in cloud computing, security is still a critical challenge in cloud computing paradigm. These challenges include user’s secret data (like health and financial data) loss, leakage and disclosing of privacy. We have studied literature and discussed various model in cloud computing, it shows that privacy/protection in cloud is still immature.
