Computing gives people to store enormous data efficiently and economically since it depends on third party management security is the million dollar question. In order to provide protection over the private data user can encrypt the data and can upload in cloud. Encryption process could be done by Advanced Encryption Standard (AES) algorithm which is highly secure and unbreakable. Encrypted data with key management play significant role in cloud computing in order to get decrypted data user should appropriate key for the file to get decrypted data which would be transferred very securely. Proposed system try to avoid update of unwanted data like inappropriate sentences will be avoided from malicious user to misuse the data .The concept of data mining plays a  vital role. This concept of combination of cloud computing and data mining gives us the good result of security of personal detail and unwanted data would not accommodate on the internet .This process would help mostly on providing authenticated data by only legitimate user can access the data even legitimate user cannot find the decrypted content if unwanted data exist in the file. This approach have overcome security issues of own personal or organization data.

Cloud Computing makes immense use of internet to store a huge amount of data. Cloud computing provides high quality service with low cost and scalability with less requirement of hardware and software management. Security plays a vital role in cloud as data is handled by third party hence security is the biggest concern to matter. This proposed mechanism focuses on the security issues on the cloud. As the file is stored at a particular location which might get affected due to attack and will lost the data. So, in this proposed work instead of storing a complete file at a particular location, the file is divided into fragments and each fragment is stored at various locations. Fragments are more secured by providing the hash key to each fragment. This mechanism will not reveal all the information regarding a particular file even after successful attack. Here, the replication of fragments is also generated with strong authentication process using key generation. The auto update of a fragment or any file is also done here. The concept of auto update of filles is done where a file or a fragment can be updated online. Instead of downloading the whole file, a fragment can be downloaded to update. More time is saved using this methodology.

Cloud computing provides means of increasing the capacity or adding the capabilities which releases the heavy data user. It provides gigantic storage for data and faster computing to the customers on the internet. It transfers database and application software from the data owner to the cloud where management and maintenance of data take place. Security of data in cloud is one of the major issues which acts as an obstacle in the development of cloud computing. In this paper, an efficient model is proposed to protect the data in the process of transferring data to the cloud and get the data from the cloud. We take many precautions and measures to guarantee the security of data. To shield owners data from the malicious third party, RSA is used to encrypt data to cipher text. Because it is difficult to search data from the encrypted data, we take the technique of index the document by the keyword and then encrypt the index and send index with encrypted original data. To check the integrity of data, digital signature is taken to identify modifications of data. This article also introduces the concrete the underlying datacenter structure named Megastore and how Megastore functions seamlessly width owners while owners store data and retrieve data from the underlying datacenter. Megastore stores fine-gained partitions of data into different datacenters and the partitioning allows us to synchronously replicate each write to across wide area with reasonable latency and support seamless failover between different datacenters.

With the advent of cloud computing, data privacy has become one of critical security issues and attracted much attention as more and more mobile devices are relying on the services in cloud. To protect data privacy, users usually encrypt their sensitive data before uploading to cloud servers, which renders the data utilization to be difficult. The ciphertext retrieval is able to realize utilization over encrypted data and searchable public key encryption is an effective way in the construction of encrypted data retrieval. However, the previous related works have not paid much attention to the design of ciphertext retrieval schemes that are secure against inside keyword-guessing attacks (KGAs). In this paper, we first construct a new architecture to resist inside KGAs. Moreover we present an efficient ciphertext retrieval instance with a designated tester (dCRKS) based on the architecture. This instance is secure under the inside KGAs. Finally, security analysis and efficiency comparison show that the proposal is effective for the retrieval of encrypted data in cloud computing.

Security Issues

Cloud is considered as future of Information Technology. User can utilized the cloud on pay-as-you use basis. But many organizations are stringent about the adoption of cloud computing due to their concern regarding the security of the stored data. Therefore, issues related to security of data in the cloud have become very vital. Data security involves encrypting the data and ensuring that suitable policies are imposed for sharing those data. There are several data security issues which need to be addressed. These issues are: data integrity, data intrusion, service availability, confidentiality and non-repudiation. Many schemes have been proposed for ensuring data security in cloud environment. But the existing schemes lag in fulfilling all these data security issues. In this chapter, a new Third Party Auditor based scheme has been proposed for secured storage and retrieval of client's data to and from the cloud service provider. The scheme has been analysed and compared with some of the existing schemes with respect to the security issues. From the analysis and comparison it can be observed that the proposed scheme performs better than the existing schemes.
