Paper Details

Cloud systems have become extremely popular in the past few years. There has been rapid growth in theamount of data in regards to information systems in the past few years. A critical issue needs to be taken care of whileconsidering cloud storage which is duplication. According to a recent research around 70-80% of data on cloud serversis redundant which can be a disadvantage. To solve this problem data deduplication is brought into picture.Deduplication means saving only one copy of a particular file on the cloud which proves to prevent wastage of spaceover cloud by deleting the duplicated data. This also helps in easy maintenance and cost effective methods of saving dataover a cloud environment.In this paper the system works on the problem of integrity auditing and secure deduplication of data in cloud.This calls for the introduction of two systems i.e. SecCloud and SecCloud+. SecCloud is designed to help the client auditthe stored data and generate data tags before client uploads the file on the server. SecCloud has reduced thecomputational load that the user faces during the auditing and uploading phase. SecCloud+ guarantees theconfidentiality of file besides securing the deduplication and performing integrated auditing. Encryption largely helps insecuring clients data which can be saved if pursued by malicious attacks this also enables integrity auditing and securededuplication on encrypted data. The proposed system supports authorized deduplicate check in cloud architecture.
