Faithful Squashed Entanglement [PDF]
, 2011 Squashed entanglement is a measure for the entanglement of bipartite quantum states. In this paper we present a lower bound for squashed entanglement in terms of a distance to the set of separable states.

A novel reversible data hiding based on adaptive block‐partition and payload‐allocation method
IET Image Processing, 2021 A reversible data hiding method based on partition is researched because it can effectively reduce shifting distortion in given embedding capacity. However, traditional partition is to divide an image into equal‐sized blocks, which cannot be divided ...

Efficient Reversible Data Hiding Simultaneously Exploiting Adjacent Pixels
IEEE Access, 2020 As an effective means to content authentication and privacy protection, reversible data hiding (RDH) permits us to hide a payload such as authentication data in a media file. The resulting marked content will not introduce noticeable artifacts.

Improving preprocessing in reversible data hiding based on contrast enhancement
Journal of King Saud University: Computer and Information Sciences, 2022 In this paper, we propose an improvement in the preprocessing stage of the reversible data hiding method based on contrast enhancement applied to grayscale digital images. In conventional proposals, the preprocessing stage plays a fundamental role in the

Very fast watermarking by reversible contrast mapping
, 2006 Reversible contrast mapping (RCM) is a simple integer transform that applies to pairs of pixels. For some pairs of pixels, RCM is invertible, even if the least significant bits (LSBs) of the transformed pixels are lost.
