In this paper we introduce a secure deduplication scheme for near identical (NI) images using the Dual Integrity Convergent Encryption (DICE) protocol. An image is divided into blocks and the DICE protocol is applied on each block separately instead of applying on the entire image. As a result, the blocks that are similar between two or more NI images are deposited only once at the cloud. This paper provides a technique to accomplish secure image deduplication at the block level based on the DICE protocol which exhibits that the greater the resemblance of the images, the smaller the number of blocks deposited at the cloud. Applying secured data deduplication to such data files could remarkably minimize the cost and space required for their storage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
