Abstract
Cloud computing is an emerging computing paradigm in which information technology resources and capacities are provided as services over the internet. The users can remotely store their data into the cloud so that the users can be relieved from the burden of local data storage and maintenance. The user does not have any control on the remotely located data. This unique feature possess many security challenges. One of the important concern is the integrity of data and computations. To ensure correctness of user’s data in the cloud, an effective scheme assuring the integrity of the data stored in the cloud is proposed. We try to obtain and prove that the data stored in the cloud is not modified by the provider, thereby ensuring the integrity of data. To ensure secure computation our scheme uses the Merkle hash tree for checking the correctness of computations done by the cloud service provider. Algorithms are implemented using java core concepts and java Remote Method Invocation (RMI) concepts for client-server communication by setting up the private cloud environment with eucalyptus tool. This method is used to assure data integrity and secured computations with reduced computational and storage overhead of the client.

Summary
Cloud computing is a pay-per-use model for enabling available, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Cloud computing refers to the delivery of scalable IT resources over the internet, as opposed to hosting and operating those resources locally, such as on a college or university network Those resources can include applications and services, as well as the infrastructure on which they operate. There are numerous security and privacy (Pearson, 2009) issues for cloud computing as it encompasses many technologies including networks, databases, operating systems, virtualization, resource scheduling, transaction management, load balancing and memory management. These issues fall into two broad categories-security issues faced by cloud providers and security issues faced by their customers. The cloud security is divided into two classes
