Study On Secure Data Deduplication System With Application Awareness Over Cloud Storage Systems
This paper gives study of data deduplication technique and how to secure data on cloud with deduplication
scheme. Data deduplication is single instance data storage widely used in cloud storage system to reduce space and upload
bandwidth. Duplication-less storage system which deduplicates the data using file level deduplication and block level
deduplication. The deduplication is done at source where data is generated and at target where data is stored that is cloud
storage system. The deduplication storage system deduplicates data with application awareness index structure. This system
consists of two major components, a front-end deduplication and a cloud storage system as back-end. Application aware
index structure improves data deduplication efficiency by exploiting application awareness and deduplication time reduction.
But for secure deduplication with application awareness we are incorporating the convergent encryption. To deal with
security issue metadata has to create first and then encrypt the file to upload to cloud storage.
