Hybrid model for Authorized De-duplication in Cloud
Prachi D. Thakar · 2015
Cloud computing provides a more cost effective environment to outsource storage computation. Many enterprises need to store and operate huge amount of data. One serious problem of today’s cloud storage service is the management of everincreasing volume of data. To make data management elastic in cloud computing de-duplication system is used. Data deduplication is a compression technique that improves storage efficiency by eliminating redundant data. In this approach we have proposed a de-duplication technique which is different from traditional de-duplication system. In this system users with differential privileges are also consider in duplicate check which was not possible in previous de-duplication system. Again in this approach we also focus on the confidentiality of sensitive data in support of de-duplication. We are proposing a Hybrid cloud approach. In Hybrid cloud approach two cloud are maintained, public cloud and a private cloud. A private cloud is working as an interface between user and public cloud. Private cloud provides a set of private key to the user. We also presented several new deduplication constructions supporting authorized duplicate check in hybrid cloud architecture.
