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.

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 is the delivery of computing services over the web instead of keeping files on a proprietary disk drive or local memory device. Computing services can include servers, storage, databases, networking, software. The main reason and great advantage for using the cloud are that the user can store and access the stored data in the cloud from anywhere anytime and getting all its services for a low cost. Despite, Security has always been a big concern with cloud computing because the information stored in the cloud is not directly maintained by the customer. When the user uploaded or stored data during a cloud computing service, the info owners are unlikely to understand the path via which their data is being transmitted. The user is unknown to the fact whether the information is being collected, analyzed, and accessed by a third party or not. To overcome the security issues various cryptography algorithm is proposed. This paper focused on the basics of cloud computing and discussed various cryptography algorithms present in the existing work.

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.

Cloud computing providing confidentiality over the insensitive data was the major issue related to security. It verifies the data owned by the server through linear computations. The proposed work enables security and efficiency using the cryptographic techniques of hybrid algorithms, securing the sensitive information that is present in the cloud. In the hybrid algorithm, it is the combination of problem encryption, key generation, result decryption and proof generation. It also validates the results which are being computed and also provides end-to-end confidentiality over the data to both the end user. The uses of hybrid algorithm results in a random key generation, encrypt/decrypt, and validate the satisfied results. This will provide a low cost to both server and client.

The primary target of this paper is to provide a secured implementing algorithm for hiding DNA sample sequence data confidently by using special software in cloud computing environments. The suggested algorithm here for hiding DNA sequences is based on binary coding and complementary pairing rules. Hence DNA reference sequence is taken as a sample secret data with a notation of M. But after applying some steps the final result obtained in cloud environment is M’’’. The procedure of identifying or extracting the original data M from the hidden DNA Reference sequence is depended on the user if and only if the user wants to use the data for process. Likewise there are security issues for the manipulating from claiming information. In this way that accessible user’s information arrangement may be isolated under SPs in such a way that it has to reach minimum number of specified threshold SPs number from the whole data block. In this paper, we recommend A low cost secured and multi- cloud storage  (SCMCS) model over cloud computing which holds an prudent appropriation about information Around the accessible SPs in the market, with gatherings gives client information accessibility and additionally secure capacity.
