Cloud computing is a revolutionary movement in the area of IT industry that provides storage, computing power, network and software as an abstraction and as a service, on demand over the internet, which enables its clients to access these services remotely from anywhere, anytime via any terminal equipment. Since cloud has modified the definition of data storage from personal computers to the huge data centers, security of data has become one of the major concerns for the developers of cloud. In this paper a security model is proposed, implemented in Cloud Analyst to tighten the level of cloud storage security, which provides security based on different encryption algorithms with integrity verification scheme. We begin with the storage section selection phase divided into three different sections Private, Public, and Hybrid. Various encryption techniques are implemented in all three sections based on the security factors namely authentication, confidentiality, security, privacy, non-repudiation and integrity. Unique token generation mechanism implemented in Private section helps ensure the authenticity of the user, Hybrid section provides On Demand Two Tier security architecture and Public section provides faster computation of data encryption and decryption. Overall data is wrapped in two folds of encryption and integrity verification in all the three sections. The user wants to access data, required to enter the user login and password before granting permission to the encrypted data stored either in Private, Public, or Hybrid section, thereby making it difficult for the hacker to gain access of the authorized environment.
