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

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 …

This paper presents a steganographic scheme based on the RGB colour cover image. The
secret message bits are embedded into each colour pixel sequentially by the pixel-value …

Steganography is a process to hide secret data into a cover media in an imperceptible
manner. In the spatial domain of image steganography, the most common technique is Least …

Steganography is a technique for embedding data in a carrier medium to remain
inconspicuous to unintended recipients. Image steganographic techniques aim to improve …

Security of information during transmission is a major issue in this modern era. All of the
communicating bodies want confidentiality, integrity, and authenticity of their secret …

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 …

A new steganographic algorithm for color images (MPSteg-color) is presented based on
Matching Pursuit (MP) decomposition of the host image. With respect to previous works …

This paper presents a new algorithm for color image based steganography. Our algorithm
adaptively determines the number of secret message bits that each pixel of cover image can …

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 …
