Commutative reversible data hiding and encryption
Security and Communication Networks, 2013 ABSTRACTThis work proposes a novel scheme of commutative reversible data hiding and encryption. In encryption part, the gray values of two neighboring pixels are masked by same pseudo‐random bits. In data‐hiding part, the additional data are embedded into various bit planes with a reversible manner, and a parameter optimization method based on a ...

Reversible Data Hiding Schemes for Deoxyribonucleic ACID (DNA) Medium [PDF]
, 2009 [[abstract]]Nowadays, plenty of data hiding schemes are proposed. To have the stego data unnoticeable, the stego-media must be meaningful. Different from the products of the data hiding schemes and the traditional encryption ones, DNA is not only random ...

Memristive‐Gated RC‐Delay Synaptic Transistors for Time‐Encoded Analog in‐Memory Computing
Advanced Functional Materials, EarlyView.A Memristive‐Gated Transistor for Time‐Encoded Analog In‐Memory Computing — By exploiting the RC delay of a self‐rectifying interface‐type memristor, nonlinear I–V distortion is structurally bypassed, enabling 3‐bit nonvolatile memory, spike‐timing‐based analog encoding, and hardware‐calibrated reservoir‐computing validation within a unified device ...

A Novel Reversible Data Hiding Scheme Using Ripple Strategy and Histogram Shifting
, 2014 [[abstract]]In this paper, we propose a reversible data hiding method based on pixel difference histogram shifting and ripple strategy. Because the local area has similar pixel value distribution in the natural image, the pixel differences will be ...

Reversible Tuning of Multiple Molecular Kinking for Stem Cell Regulation In Vivo
Advanced Functional Materials, EarlyView.In this work, we introduce the novel concept of background component‐free “multiple kinks” material platform composed solely of liganded multiple kink‐bearing molecules as a strategy for dynamic biomaterial design. Tri‐kink molecules enable effective near‐infrared light‐triggered ligand masking and visible light‐triggered ligand exposure, thereby ...

An Overview of Reversible Data Hiding
, 2003 Reversible data hiding is the technique that allows embedding (hide) data inside an image and later the hidden data can be retrieved as required and the exact copy of the original image is found.
