Secure data transmission through reversible data hiding

2016 Online International Conference on Green Engineering and Technologies (IC-GET), 2016
Data hacking is very difficult to deal with today's electronic world. There are large numbers of technique used, for the secure communication of data. Images are widely used in different-different processes. So data hiding is used in the encrypted image, but the main problem is that distortion at the time of data extraction.

Survey on reversible data hiding techniques

2016 3rd International Conference on Advanced Computing and Communication Systems (ICACCS), 2016
Data transmissions using computer networks has created the need for security. Many robust message encryption techniques have been developed to supply this demand. Steganography is one form of cryptography where we hide data within large texts or images.

Optimal PPVO-based reversible data hiding

Journal of Visual Communication and Image Representation, 2017
Abstract The optimal PPVO-based reversible data hiding (RDH) including adaptive prediction pattern and optimal bin selection is proposed in this paper. By reasonably designing the prediction pattern, each to-be-embedded pixel can be predicted by the n ( n ∈ { 4 , … , 13 } ) neighbors surrounding it.

Reversible Data Hiding for Video

2018
Difference expansion (DE) and histogram modification (HM) are efficient ways for reversible data hiding (RDH) into digital video. In most occasions, the reversibility of an algorithm cannot be confirmed until the data extracting experiments have been carried out, it means the design of a reversible data hiding algorithm lacks theoretical guidance.

Improved PVO-based reversible data hiding

Digital Signal Processing, 2014
This work extends a recently proposed reversible data hiding (RDH) scheme of Li et al. which is based on pixel-value-ordering and prediction-error expansion. In Li et al.?s method, the maximum and minimum of a pixel block are predicted and modified to embed data.

Reversible Data Hiding

2005
This paper presents a novel reversible data hiding algorithm, which can recover the original image without distortion from the marked image after the hidden data have been extracted. This algorithm utilizes the zero or the minimum point of the histogram and slightly modifies the pixel values to embed data.

Histogram-Based Reversible Data Hiding

2010
This paper presents a novel histogram-based reversible data hiding technique to embed secret data into gray-scale host image. This method utilizes the difference of the pixel values of the host image and the zero or the minimum points of the histogram of the difference image and modifies the pixel grayscale values slightly to embed secret data into ...

Adaptive reversible data hiding through autoregression

2012 IEEE International Conference on Information Science and Technology, 2012
An adaptive reversible data hiding method through autoregression is presented in this paper. In the proposed algorithm, we focus on the image pixel value prediction, which plays a key role in the data embedding process. Unlike conventional data hiding techniques, a threshold is adjusted for each image to divide all pixels into two regions: the smooth ...

Reversible Data Hiding

2019
The chapter presents an application of reversible data hiding for the authentication of image travelling over a hostile and insecure communication channel. The reversible data resides in the image and tracks any changes done to it on a communication channel. The extraction of data and any modification to its structure reveals changes in the image. This
