Information security and privacy are equally extremely important issues in IT industry. In the cloud processing technology, it becomes especially critical since the information is situated in various places even in the whole globe. Information security and privacy protection are the two major facets of user's considerations in regards to the cloud processing technology. However several methods on the issues in cloud processing have already been investigated in academics and industries, information safety and privacy safety are getting more crucial for future years growth of cloud processing in government, market and business. Information protection and privacy protection problems are strongly related equally hardware or equipment or electronics and computer software or application in the cloud architecture. This study is to examine various information protection methods and difficulties from both computer software or application and hardware or equipment or electronics factors for guarding information in the cloud and seeks at improving the information protection and solitude safety for the reliable cloud environment. In this research paper, we create a relative evaluation of the present research work regarding the data security and privacy issues found in the cloud computing technology. Keywords: Privacy, Malicious, Access Control, Security, Fine-Grained.
I. INTRODUCTIONCloud computing has been envisioned as another generation paradigm in computation. In the cloud computing environment, both applications and resources are delivered on demand over the Internet as services. Cloud is definitely an environment of the hardware and software resources in the data centers that offer diverse services over the network or the Internet to satisfy user's requirements [1].The explanation of "cloud computing" from the National Institute of Standards and Technology (NIST) [2] is that cloud computing enables ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Based on the explanation, cloud computing supplies a convenient on-demand network usage of a shared pool of configurable computing resources. Resources refer to computing applications, network resources, platforms, software services, virtual servers, and computing infrastructure. Cloud computing can be considered as a new computing archetype that will provide services on demand at a small cost. The three well-known and commonly used service models in the cloud paradigm are software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). In SaaS, software with the related data is deployed by a cloud service provider, and users can use it through the internet browsers. In PaaS, a service provider facilitates services to the users with some software packages that could solve the precise tasks. In IaaS,the cloud se...
