Abstract

Cloud storage services are widely used, due to which the volume of data on the cloud is very large. In order to avoid data redundancy and to make use of cloud storage efficiently, data deduplication is used which eliminates the storage of redundant data. Only one unique copy for each duplicate file uploaded in the cloud and the owners are referenced to that one file whenever they want to access. The objective of this paper is to automate the deduplication process while increasing confidentiality and security of the data owner and the data. The system uses user end encryption so that cloud services are not liable for data compromise. An effective comparison using hash value of different files helps in faster and secure comparison.
