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.
