Auditing and Avoiding Data Deduplication in Cloud

Abstract

Cloud storage is a place where customers, users stored data as per their requirements. Cloud storage is not
fully secure for data deduplication while achieving integrity auditing. In this work the problem of integrity auditing and
secure deduplication on cloud data by using map reduce technique. In our work, SecCloud and SecCloud+ is used to
auditing and avoiding deduplication of data. SecCloud introduced on auditing entity with Map Reduce cloud and
Reliability. Map Reduce is a framework which helps clients to generate data tags before, also it enhance the Reliability
of system because it distribute the data in block and stores on distributed network or distributed file system and master
node. For security purpose customer always wants to encrypt data before uploading and enables integrity auditing and
secure deduplication on encrypted data with the SecCloud+.IN our work used MAC protocol for tag generation.
