Steganography is an amalgamation of art and science complimenting each other where the embedding or hiding of information is done in a digital image. This paper presents a logic level design synthesis (RTL) and IC design is done in Synopsys to visualize the implementation of LSB substitution steganographic algorithm based on 8 bit images, using HDL. This paper intends to visualize and compare t...

techniques attempt to differentiate between stego-objects and cover-objects. In recent work we developed an analytic upper bound for the steganographic capacity of LSB based steganographic techniques for a given false of detection. In this paper we look at adaptive steganographic techniques. Adaptive steganographic techniques steps to escape detection. We explore different techniques that can b...

Embedding messages bits in a cover-object affects the first order statistical properties of the cover-object. In this paper a new technique is introduced to hide information bits in the redundant bits of JPEG images with preserving the statistical properties. This technique proved to defeat the visual and statistical attacks and offer higher capacity than existing steganographic systems. [Hamdy...

This paper proposes a steganalysis technique for both grayscale and color images. It uses the feature vectors derived from gray level co-occurrence matrix (GLCM) in spatial domain, which is sensitive to data embedding process. This GLCM matrix is derived from an image. Several combinations of diagonal elements of GLCM are considered as features. There is difference between the features of stego...

Watermarking has been used time and again for authentication & security of Video. Digital watermarking refers to embedding watermarks in a multimedia documents and files in order to protect them from illegal copying and identifying manipulations. Watermarking is a promising solution to protect the copyright of multimedia data through Transcending, because the embedded message is always included...

In this paper new algorithm proposed for digital watermarking using Least Significant Bit (LSB) .LSB already used but there is a slightly effect on the image. The above algorithm is using LSB & second LSB bit. Here we used binary value of watermark text in LSB, and in place of second LSB, the inverse of their correspond LSB bit. The proposed algorithm is flexible depending on the length of wate...

Watermarking is an important technique used for copyright protection, authentication, tamper detection and hiding secret information in multimedia contents. In this article a new digital watermarking scheme is proposed based on multiple parameter discrete fractional Fourier transform and using least significant bit (LSB) technique. The multiple parameter discrete fractional Fourier transform (M...

In this paper, description of a compression algorithm based on steganography has been narrated. The compression algorithm has been used to develop an application which will help the users to hide large size text documents inside small size images. Maximum bits to be hidden per pixel can be increased to eight with the help of the developed compression application. After hiding the data inside an...

This paper presents a novel steganalysis scheme with highdimensional feature vectors derived from co-occurrence matrix in either spatial domain or JPEG coefficient domain, which is sensitive to data embedding process. The class-wise non-principal components analysis (CNPCA) is proposed to solve the problem of the classification in the high-dimensional feature vector space. The experimental resu...
