ABSTRACT:

Cloud computing has been envisioned because the de-facto answer to the rising storage costs of IT Enterprises. With the high prices of knowledge storage devices also because the speedy rate at which information is being generated it proves pricey for enterprises or individual users to frequently update their hardware. Apart from reduction in storage costs knowledge outsourcing to the cloud additionally helps in reducing the maintenance. Cloud storage moves the user's information to giant data centers, that are remotely located, on that user does not have any management. However, this unique feature of the cloud poses many new security challenges that would like to be clearly understood and resolved. One of the important concerns that require to be addressed is to assure the client of the integrity i.e. correctness of his knowledge in the cloud. As the data is physically not accessible to the user the cloud should offer a approach for the user to test if the integrity of his knowledge is maintained or is compromised. In this paper we have a tendency to give a scheme which offers a symptom of information integrity within the cloud which the customer can use to test the correctness of his knowledge in the cloud. This proof can be specified by both the cloud and the customer and will be incorporated within the Service level agreement (SLA). This theme ensures that the storage at the client side is minimal which will be beneficial for thin shoppers.
