In this paper, we proposed methods to accurately predict pixel values by effectively using
local similarity, curved surface characteristics, and edge characteristics present in an image …

Steganography has been a common mode of secret communication in recent years.
Although the steganographic approach can be carried out in either image, audio or video …

In this paper, we propose a new reversible data hiding scheme that uses pixel value
adjusting feature. It has two phases. In first phase, It scans the image diagonally from left to …

Recently, Luo et al. proposed a new block-based reversible data hiding method that divides
an image into blocks, sorts all pixels within a block and then chooses the middle sorted pixel …

Image Steganography is one of the most well-known methods where a top-secret data is
embedded into the pixels of an image by altering some of its pixel values. Reversible Image …

A novel prediction-based reversible steganographic scheme based on image in-painting is
used to embed the secret information. First, reference pixels are chosen adaptively …

In this paper, a new reversible data hiding scheme has been proposed using lagrange's
interpolating polynomial on interpolated sub-sampled images. First, we generate sub …

The science of hiding secret information in a message is known as steganography; hence,
the presence of secret information is concealed. It is the method of hiding cognitive content …

Data hiding is a noteworthy research topic in digital technology for years. Reversible data
hiding (RDH) technique plays a vital role for confirming security of the digital transmissions …

Owing to the inefficiency to hide large volume of secret data for the reversible data hiding
(RDH) image steganography approaches, we propose two improved RDH based …
