Cloud Computing is an latest up growing technology which provide various services to internet, it enables to store the data in to a cloud storage and the on demand scalable services.The users should use the cloud storage data as it is local without verifying its integrity and correctness of data.The public auditing for cloud storage is important, so that to check the integrity of outsourced data in the cloud, the users will take the action to check the integrity of data in a Intermediate Cloud Accessor (TPA) .To securely introduced an effective Intermediate Cloud Accessor (TPA), the auditing processor should bring an new concerns for user data privacy, for that the watermarking for data storage security in cloud computing is proposed.It supports data dynamics where users can perform various operations on data like insert, update and delete as well as batch auditing where multiple user request for storage correctness will be handled simultaneously which reduces the communication and computing cost.
