Steganography is a data-concealing technique that provides a covert communication. This
paper proposes a spatial domain color steganography method that uses a neighboring pixel …

Information security has become a cause of concern because of the electronic
eavesdropping. Capacity, robustness and invisibility are important parameters in information …

In a gray scale image the pixel value ranges from 0 to 255. But when we use pixel-value
differencing (pvd) method as image steganographic scheme, the pixel values in the stego …

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) …

Steganography is the technique for hiding information within a carrier file so that it is
imperceptible for unauthorized parties. In this study, it is intended to combine many …

Steganography is the only answer for secure and secret communication. Existing methods in
image steganography focus on increasing embedding capacity of secret data. According to …

Steganography is the process of implanting secret message in a cover data without causing
degradation neither to the cover information nor to the secret message implanted in the …

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 …

Several problems arise among the existing LSB-based image steganographic schemes due
to distortion in a stegoimage and limited payload capacity. Thus, a proposed scheme has …

Steganography, a way for covert data communication, aims to send some secret messages
via embedding them into digital image imperceptibly. This paper proposes a new adaptive …
