Cloud computing is a style of computing where computing resources and are easy to obtain and access, simple to use, cheap. Cloud data user does not possess direct control of his data, security is one of the few challenging issues which need to be addressed. To prevent data access from unauthorized access, it proposes a distributed scheme to provide security of the data in cloud. This could be achieved by using homomorphism token with distributed verification of erasure-coded data. Proposed scheme perfectly stores the data and identifies the any tamper at the cloud server and also performs some operations like data updating, deleting and appending. The proposed design allows users to audit the cloud storage with very lightweight communication and computation cost.Cloud computing has gained great attention from both industry and academia since 2007.One of the core services provided by cloud computing is data storage. The security of data storage is one of the necessary tasks to be addressed before the blueprint for cloud computing is accepted.In the past decades, data storage has been recognized as one of the main concerns of information technology. The benefits of network-based applications have led to the transition from server-attached storage to distributed storage.
