Achieving Data Consistency in the Bigdata Systems by Providing a Secure Deduplication Scheme on Encrypted Data

Abstract

In the cloud environment, if we want store or upload any data into the cloud, we require minimum security to our data. Presently, we can encrypt our data based on some access policies which are related to the data owner as well as data user. If we add attribute set to the access policies to access the data from cloud, then we can say this is the Attribute-Based Encryption (ABE). However we used the ABE scheme, we are not able to provide secure deduplication to the cloud data. To improve the secure deduplication, in this paper we are implementing an attribute-based storage system and it can useciphertext-policy attribute-based encryption (CPABE) and supports secure deduplication. By using this proposed scheme, we can save the cloud storage space and also we can provide security to the cloud data.
