This paper presents analysis of Least Significant Bit (LSB) based Steganography and Discrete Cosine Transform (DCT) based Steganography. LSB based Steganography embed the text message in least significant bits of digital picture. Least significant bit (LSB) insertion is a common, simple approach to embedding information in a cover file. Unfortunately, it is vulnerable to even a small image mani...

Massive low surface brightness galaxies have disk central surface brightnesses at least one magnitude fainter than the night sky, but total magnitudes and masses that show they are among the largest galaxies known. Like all low surface brightness (LSB) galaxies, massive LSB galaxies are often in the midst of star formation yet their stellar light has remained diffuse, raising the question of ho...

<strong><em>Steganography is a technique or art to hide secret message into cover so that the existence of cannot be known by other people third parties who do not have ability know contents message.

Steganography is the science of hiding secret data inside another type as image and text. This known carrier data; it lets people interconnect secretly. suggested paper aims to design a Biometric Imaging System (SBIS). The system constructed in hybridization manner between processing, steganography, artificial intelligence techniques. During processing techniques receives RGB foot-tip images pr...

This research proposes a method to enhance the payload message by embedding messages on dilated edge areas Least Significant Bit (LSB) method. To add security aspects messages, are not embedded directly LSB but encrypted with XOR operations Most (MSB). The experimental results of test in this study showed that dilation process some extent can increase 18.65% and average bpp is 1.42 while mainta...

In digital steganography normally image, audio or video files are the standard cover files or the host files for embedding secret message such as text, image, audio or video. Nath et al.(2) explored the standard method for hiding secret message inside standard cover files such as image, audio or video files. In the present work we have shown how we can hide secret message in encrypted form in s...

Aiming at the problem that data hiding algorithm of high efficiency video coding (HEVC) has great influence on bit rate and visual quality, an information based intra prediction mode matrix is proposed. Firstly, 8 modes are selected from 4×4 luminance blocks in I frame to embed hidden information. Then, Least Significant Bit (LSB) used modulate LSB last mode. Finally, modulated block re-encoded...

Context. The exact formation scenarios and evolutionary processes that led to the existence of the class of low surface brightness galaxies (LSBs) have not yet been understood completely. There is evidence that the lack of star formation expected to be typical of LSBs can only occur if the LSBs were formed in low-density regions. Aims. Since the environment of LSBs has been studied before only ...

we present a steganalysis scheme for lsb matching steganography based on feature vectors extracted from integer wavelet transform (iwt). in integer wavelet decomposition of an image, the coefficients will be integer, so we can calculate co-occurrence matrix of them without rounding the coefficients. before calculation of co-occurrence matrices, we clip some of the most significant bitplanes of ...
