Information deduplication is a technique for removing copy duplicates of information, and has been widely used in reasoning storage to reduce storage space and publish data transfer usage. Appealing as it is, a coming up challenge is to perform secure deduplication in cloud storage. Secure data outsourcing is main concept in cloud computing environment for processing efficient data sharing between different users in distributed cloud environment. Data storage is also efficient task in cloud so the proceedings of duplications in cloud are a crucial issue in real time cloud data storage process. In this paper we formalize different techniques/methods for secure deduplication in cloud data storage. Different techniques/methods formalize to precede their activities in duplication maintenance in secure data storage. Our final proceedings give better efficient results in secure cloud storage with different techniques/methods advantages and disadvantages in real time cloud environment.
