Opis:: This document presents a conceptual model of a system for protecting thedata stored in publicly available data storage systems. The main idea was toapply encryption on both the client and server sides that would consequentlyhave a significant impact on data security. The compatibility with existingsystems allows us to deploy the solution fast and at a low cost. The testsconducted on a simplified implementation have confirmed the solution’s validity,and they have shown some possible performance issues as compared to theclassical system (which can be easily bypassed).

Opis:: Research into the domain of reversible data-hiding has received a great deal of attention in recent years due to its wide applications in medical image transmission and cloud computing. Reversible data-hiding during image encryption is a recently emerged framework for hiding secret data in an image during the image-encryption process. In this manuscript, we propose a new reversible data-hiding-through-encryption scheme that will ensure a high embedding rate without bringing any additional overhead of key handling. The proposed algorithm can use any secure symmetric encryption scheme, and the encryption and/or decryption key should be shared with the receiver for data extraction and image recovery. As per the proposed scheme, the data hider can hide threebits of a secret message in an image block of a size of B × B pixels. The data extraction and image recovery will be carried out by analyzing the closeness between adjacent pixels. The simulation of the new scheme carried out on the USC-SIPI dataset shows that the proposed scheme outperforms the well-known existing schemes in terms of embedding rates and bit error rates.
