Survey Paper on Authorized De-Duplication of Image and Text in Cloud

Abstract

Effective file storage and management system is very important today in order not to waste storage space provided by cloud providers. Data deduplication technology is widely used and can save only a single copy of a file, thus avoiding duplication of files on cloud storage servers. It can reduce storage capacity and save bandwidth for cloud services, resulting in significant cost savings for cloud service subscribers. Currently, the data that needs to be stored is in encrypted form to ensure security. Therefore, if data owners use their own keys to encrypt their data, cloud service subscribers will not be able to deduplicate it.
