Cloud Data Duplication Identification using Hash Code

Storage and security for all data is very important for cloud computing. Securing and privacy preserving of data is of high priority when it comes to cloud storage.De-duplication is a process that eliminates redundant copies of data and reduces storage overhead. Storage and data transfer costs will be reduced by their cloud providers by storing a unique copy of duplicate data. The most often important and popular cloud service is data storage. Intrusion detection and prevention are performed manually by network operators in the existing system. When the utilization of such private cloud storage increases, there will be an increase in the connection problem, performance storage demand, privacy security, data integrity. The key idea behind the develop a dynamicload balancing algorithm based on de-duplication to balance the load across the storage expansion of private cloud storage. For maintaining privacy, security data integrity we will use SHA algorithm. SHA algorithm also used to avoid duplication. The result also show the comparison of various hashing algorithms and show SHA is more secure and take less time than other hashing algorithms. The base scheme without de-duplication checking scheme take more storage space and time also increases.
