An effective steganographic scheme is proposed that combines pixel-value differencing,
modulus function, and particle swarm optimization on the basis of previous research. In this …

Steganography is the science of hiding a secret message in cover media, without any
perceptual distortion of the cover media. Using steganography, information can be hidden in …

The main purpose in developing the steganographic algorithms lies in achieving most of the
steganographic objectives which comprise the embedding capacity, imperceptibility …

In today's technological world, one of the most challenging problems is information security.
In the past ten years, many methods were introduced for securing the secret data …

This paper present a steganalysis method for the data hiding scheme based on VQ-
compression. This data hiding algorithm divides the codebook into groups which contain two …

Steganography is the science of hiding a message signal in a host signal, without any
perceptual distortion of the host signal. Using steganography, information can be hidden in …

In this paper, we present an efficient scheme of color image steganography based on Mix
Column Transform (MCT) on specified blocks selected according to secret key and hide the …

In this paper, we compare Huffman coding and Arithmetic coding with ASCII coding to
observe their contribution to steganography. This way is to compress the embedded …
