摘要：Dynamic Proof of storage, (DyPos) is a cryptographic technique which permits the user to check thereliability of the data which is outsourced, it also enables the user to modulate the data in block level and finally itavoids storing of exact copy of the content which is already present in storage devices. For single user environmentthere are several techniques are available, but when considering the multi user environment many issues need to besolved efficiently.A secured content replication check technique has to be needed in the client side to avoid duplicationby stopping the upload process of the replicated file content and make the best use of storage device capacity. As of theliterature survey no existing systems are doing this job.This work introduces the idea ofdeduplicatable dynamic proofof storage and propose an efficient new tool called as Homomorphic Authenticated Tree (HAT) to overcome the issuesof structure diversity and private tag generation. This work is trying to prove the safety of the structure, theoreticalanalysis and also experimental results are efficient for checking the deduplication of a file on cloud.
