Secure sharing in cloud using regenerated code

Cloud Computing is a service that allows users to store data on offsite storage system managed by third-party and is accessible by a web service API. Data access control is an effective way to ensure the data security in the cloud. The Protection of data integrity and privacy has become one of the issue in cloud computing. The Private auditing technique is achieved by the emergence of the Regenerating code. Regenerating code provide lower bandwidth and fault tolerance. This method requires data owners to stay online and handle auditing. In the proposed paper, we present a public auditing scheme for the regenerating-code based cloud storage. This method solves the regeneration problem in the absence of data owners. The users ask the Third Party Auditor (TPA) to check the integrity of the data. Moreover to preserve data privacy, the data’s are encrypted using AES algorithm. Thus our scheme is highly secure and can be feasibly integrated into the regenerating code based cloud storage. The MD5 technique is efficiently used in order to protect the data.
