<p>Cloud data security is one of the major and crucial concern in everyday life. Now a days cloud computing is emerging as vast and fastest growing technology depending on the usage. Cloud computing does not allow to keep data at user site and thus a data security is concerned to be a major challenging task regarding data storage. This paper overall describes the monitoring of the cloud data concerning data storage. In this paper we proposed a new methodology that can efficiently managed the security to the data and provide privacy to the consumer using the services of the cloud. Our proposed technique provides data security by using the third party monitoring system which acts as an interface between the cloud consumer and cloud owner. Basically third party monitors the each and every activity of the cloud consumer and based upon his performance he respond to the cloud owner for taking decision. Our proposed concept provides the security from consumer point of view and owner side of view making the flexibility to the cloud infrastructure. Existing work focus mainly on security from owner side of view that not well fitted into the lifecycle of data security.</p>

Cloud Data Storage

The most demanded advanced technology throughout the world is cloud computing. It is one of the most significant topics whose application is being researched in today’s time. Cloud storage is one of the eminent services offered in cloud computing. Data is stored on multiple third-party servers, rather than on the dedicated server used in traditional networked data storage in the cloud storage. All data stored on multiple third-party servers is not bothered by the user and no one knows where exactly data saved. It is minded by the cloud storage provider that claims that they can protect the data but no one believes them. Data stored over the cloud and flowing through the network in the plain text format is a security threat. This paper proposes a method that allows users to store and access the data securely from cloud storage. This method ensures the security and privacy of data stored on the cloud. A further advantage of this method is we will be using encryption techniques to encrypt.

Identity Based

Cloud computing has emerged as a new promising field in the internet. It can be thought as a new architecture for the next generation of IT enterprises. It allows the user to access virtualized resources over the internet which can be dynamically scaled. Here, the owner's data is stored at a distributed data centre, which are responsible for its security constraints such as access control and data transmission to user. As the owner does not have physical access on their own data, the data centres are not trustworthy, this resulted in the cloud data security demand. Today, many cloud service providers (CSPs) are using the asymmetric and public key cryptography (PKG) for authenticating and data security purposes using the digital identity of the user. To this end, this article focuses on cloud data storage and its delivery to authorized user. For this purpose, a hierarchal identity-based cryptography method is used for data security and checking the data integrity, in order to make sure that there is no alteration or modification done by a malicious attacker or CSP for its own benefit.

Encryption Decryption

Cloud storage is one among the service provided by Cloud computing within which information is maintained, managed, secured remotely and created available to users over a network. The user concerning about the integrity of data hold on within the cloud because the user’s data will be attacked or changed by outside attacker. Therefore, a new thought referred to as information auditing is introduced that check the integrity of knowledge with the assistance of an entity referred to as Third Party Auditor (TPA). The aim of this work is to develop an auditing scheme that is secure, economical to use and possess the capabilities like privacy conserving, public auditing, maintaining the information integrity together with confidentiality. It comprises 3 entities: data owner, TPA and cloud server. The data owner performs numerous operations like splitting the file to blocks, encrypting them, generating a hash value for every, concatenating it and generating a signature on that. The TPA performs the main role of knowledge integrity check. It performs activities like generating hash value for encrypted blocks received from cloud server, concatenating them and generates signature on that. It later compares each the signatures to verify whether or not the information stored on cloud is tampered or not. It verifies the integrity of data on demand of the users. To make sure data protection or security of cloud data storage at cloud end, security architecture is designed that secures the data using encryption/decryption algorithm where the proposed algorithm is a hybrid encryption algorithm that uses the concept of EC-RSA, AES algorithm and Blowfish algorithm along with SHA-256 for auditing purpose. Presented experiment results show that the proposed concept is reasonable, it enhancing efficiency about 40% in terms of execution time i.e. encryption as well as decryption time and security and providing confidentiality of cloud data at could end.

Cloud is an emerging technology that stores the necessary data and electronic form of data is produced in gigantic quantity. It is vital to maintain the efficacy of this data the need of data recovery services is highly essential. Cloud computing is anticipated as the vital foundation for the creation of IT enterprise and it is an impeccable solution to move databases and application software to big data centers where managing data and services is not completely reliable. Our focus will be on the cloud data storage security which is a vital feature when it comes to giving quality service. It should also be noted that cloud environment comprises of extremely dynamic and heterogeneous environment and because of high scale physical data and resources, the failure of data centre nodes is completely normal.Therefore, cloud environment needs effective adaptive management of data replication to handle the indispensable characteristic of the cloud environment. Disaster recovery using cloud resources is an attractive approach and data replication strategy which attentively helps to choose the data files for replication and the strategy proposed tells dynamically about the number of replicas and effective data nodes for replication. Thus, the objective of future algorithm is useful to help users together the information from a remote location where network connectivity is absent and secondly to recover files in case it gets deleted or wrecked because of any reason. Even, time oriented problems are getting resolved so in less time recovery process is executed.
