SECURE DISTRIBUTED DEDUPLICATION SYSTEM TO IMPROVE DATA INTEGRITY IN CLOUD USING TPA

Information deduplication is a system for taking out duplicates of information, for better utilization of storage room and data transfer capacity. There is only one copy of each document in cloud, possibility there may be N number of user for the same document. The data which is outsourced by user to cloud must b delicate information and it should be protected by leaking. In this paper we introduce TPA with secure distributed system for information integrity and tag consistency. The TPA is a public verifier that verifies that the data stored by the user is unchanged or corrupted in the cloud.
