Abstract Cloud is a Centralized Architecture Server, which serves as a platform for every user of the cloud wanted to store data and sensitive information’s in safe secured storage space. The next logical stage in the growth of on demand information technology services and products is cloud computing. Cloud computing will rely on virtualized resources to a considerable extent. Cloud computing allows IT skills to be reused, and it always includes current computing services such as distributed and grid computing. Users can perform a keyword based search over encrypted material with searchable encryption. The majority of currently available searchable encryption systems are based on a single cloud server approach, which has some drawbacks, such as a single point of failure and hostile insiders. The multi cloud server strategy, on the other hand, provides more data availability and security. However, transferring existing keyword search strategies to the multi cloud will result in higher storage and search expenses, with no discernible improvement in data security. In addition, unlike single cloud, a challenge in a multi cloud environment is how to adequately check query integrity when certain cloud servers return inaccurate or incomplete data. We offer an iterative encryption approach to assure file privacy even if numerous cloud services collude with one another to ensure data security.
