The goals of image steganography are to simultaneously reach maximum embedding
capacity, enhanced embedding efficiency, better image quality, and more security. We …

Data hiding called steganography is a security technique to protect secret data throughout
the transmission from malicious attackers. The purposes of steganography are to obtain …

Many existing steganographic methods hide more secret data into edged areas than smooth
areas in the host image, which does not differentiate textures from edges and causes …

Summary Least Significant Bit (LSB) is a common and popular technique for steganographic
images, especially when the spatial domain of an image is considered. Because of its high …

To enhance the embedding capacity of image steganography and provide an imperceptible
stego-image for human vision, a novel adaptive number of least significant bits substitution …

Steganography is the art and practice of communication using hidden messages. The least
significant bits (LSB) based method is the well-known type of steganography in the spatial …

In order to improve the capacity of the hidden secret data and to provide an imperceptible
stego-image quality, a novel steganographic method based on least-significant-bit (LSB) …

The challenge of steganographic methods is to create a rational balance between the
quality of the file and the size of data that can be transferred. In addition, the robustness of …

In this paper, a steganography technique using LSB substitution and PVD method is
presented as an adaptive scheme in the spatial domain. Our method partitions the grayscale …

Various image steganography methods have been developed to improve the stego image
quality, ie imperceptibility, capacity, and security. This research proposes an adaptive …
