Secure Data Deduplication on Hybrid Cloud Storage Architecture

Data deduplication is one of the most important Data compression techniques used for to removing the identical copies of repeating data and it is used in the cloud storage for the purpose of reduce the storage space as well as save bandwidth. To retain the confidentiality of sensitive data while supporting the deduplication, to encrypt the data before outsourcing convergent encryption technique has been proposed . This project makes the first attempt to formally address the problem of authorized data deduplication giving better protect data security, Different from the traditional deduplication system, distinctive benefits of the user are further considered the duplicate check besides the data itself. Hybrid cloud architecture having various new deduplication constructions supporting authorized duplicate check. The proposed security models contain the illustration of security analysis scheme. As a proof of concept, contains the implementation framework of proposed authorized duplicate check scheme and conduct experiments using these prototype. In proposed system contain authorized duplicate check scheme sustain minimal overhead compared to normal operations. DOI: 10.17762/ijritcc2321-8169.15059

Review Paper on Privacy Preservation Techniques in Cloud

In this information world, large amounts of data are collected and analyzed every day. Cloud computing is the most known model for supporting large and complex data. Organizations are moving toward cloud computing for getting benefit of its cost reduction and elasticity features but cloud computing has potential risk and vulnerabilities. One of major problem in moving to cloud computing is its security and privacy concerns.Encryption is standalone problem for the security of data stored on the cloud. So we proposed method which combines the concept of encryption along with data deduplication methodology to enhance the privacy of data over cloud. Data deduplication is a specialized data compression technique for eliminating duplicate copies of repeating data in storage. In turns this technique saves the cost and time associated with redundant accessing and processing of data overhead involve as compared to normal operations.

Avoid duplicate key overheads for same data in storage

De-duplication is a technique used to weaken the amount of storage needed by service providers. Now a day the most originating challenge is to perform secure de-duplication in cloud storage. Although convergent encryption has been extensively adopted for secure de-duplication, a demanding issue of making convergent encryption practical is to efficiently and reliably managea massive number of convergent keys. We first introduce a baseline approach in which each user holds an autonomous master key forencrypting the convergent keys and outsourcing them to the server. As a proof of concept, encompass the implementation framework of proposed authorized duplicate check scheme and conduct experiments using these prototype. In proposed system involve authorized duplicate checkscheme sustain minimal overhead compared to normal operations.De-duplication is one of important data compression techniques for eliminating duplicate copies of repeating data. For that purpose Authorized duplication check system is used. This paper addresses problem of privacy preserving de-duplication in cloud computing and introduce a new de-duplication system supporting for Differential Authorization, Authorized Duplicate Check, Unfeasiblity of file token/duplicate-check token, In distinguishability of file token/duplicate-check token, Data affinity.In this project we are presenting the certified data de-duplication toprotect the data security by counting differential privileges of users in the duplicate check.Different new de-duplication constructions presented for supporting authorized duplicate check

An efficient confidentiality-preserving Proof of Ownership for deduplication

Data storage in the cloud is becoming widespread. Deduplication is a key mechanism to decrease the operating costs cloud providers face, due to the reduction of replicated data storage. Nonetheless, deduplication must deal with several security threats such as honest-but-curious servers or malicious users who may try to take ownership of files they are not entitled to. Unfortunately, state-of-the-art solutions present weaknesses such as not coping with honest-but-curious servers, deployment problems, or lacking a sound security analysis. In this paper we present a novel Proof of Ownership scheme that uses convergent encryption and requires neither trusted third parties nor complex key management. The experimental evaluation highlights the efficiency and feasibility of our proposal that is proven to be secure under the random oracle model in the bounded leakage setting. (C) 2015 Elsevier Ltd.

Secure Deduplication Technique for Privilege Data Access Using Hybrid Cloud

Cloud is moderated technology in now a days but this type of technology is failure in many times. Cloud computing having secure and confidential problems because of  data irretrievability. So we are   deliberate on faithful information. In this time the technology is focus on duplicate copies. The major idea is  we did not accept any duplicate copy like same name of file are same content of file. Then we are successfully  gain needed data on cloud     Data deduplication is a demanding technology to support dispose of redundant information as an option of enthralling records; it provisions simply distinct copy of file. Together with the whole associations reposting and numerous associations encase more bits of copy in sequence. Holder in point different clients stores corresponding documents in a few preferred spaces. Deduplication abolish the extra duplicates by trimming the  duplicate  data and restore alternate duplicates alongside pointers that flipside to the first duplicate. It represents the information pressure procedure to build the data transfer capacity proficiency. Data deduplication is tremendously utilizing as a part of distributed computing currently. Data deduplication protects the privacy of touchy data. It lives Up to expectations with merged encryption system to scramble the information before convey. Administrations frequently utilize     Deduplication technique for reinforcement and disaster recuperation functions. Here  We attempt to accept the deduplication technique, to assemble with simultaneous encryption to supervise the cost of security for sensitive information with half and half distributed computing
