A novel LSB-based image-hiding scheme that embeds secret data into the grayscale cover image is proposed in this paper. Several LSB-based image hiding schemes such as simple LSB substitution technique, optimal LSB substitution technique, greedy LSB substitution technique, modulus LSB substitution technique had been proposed. To provide good image quality of the stego-image while requiring a low...
We present N -body simulations of Low Surface Brightness (LSB) galaxies and their Interstellar Medium to investigate the cause for their low star formation rates (SFR). Due to their massive halos, stellar disks of LSB galaxies are very stable and thin. Lack of dust makes the projected edge-on surface brightness of LSB galaxies comparable to the projected edge-on surface brightness of dust-rich ...
Video steganography has become a popular option for protecting secret data from hacking attempts and common attacks on the internet. However, when whole video frame(s) are used to embed data, this may lead visual distortion.
 Materials Methods:
 This work is an attempt hide sensitive image inside moving objects in based separating object background of frame, selecting arranging them a...
This paper devotes itself to the study of secret message delivery using cover image and introduces a novel steganographic technique based on genetic algorithm to find a near-optimum structure for the pair-wise least-significant-bit (LSB) matching scheme. A survey of the related literatures shows that the LSB matching method developed by Mielikainen, employs a binary function to reduce the numbe...
the objective of this study was to evaluate genetic and phenotypic parameters for some reproductive traits of black bengal does. genetic parameters were estimated by residual maximum likelihood procedure, fitting an animal model ignoring maternal genetic or permanent environmental effects. the least-squares means of litter size at birth (lsb), litter size at weaning (lsw), litter weight at birt...
This paper reports comparative evaluations of the watermarking methods we previously proposed with four other methods. Three of the proposed methods are based on the concept of embedding inaudible watermarks into an original sound by controlling the phase characteristics of the sound in relation to the characteristics of cochlear delay (non-blind, blind, and reversal CD methods; Unoki et al., 2...
A digital image watermark is a signal permanently embedded into a digital image that can be detected or extracted later by means of some operations for authentication purposes. This paper discusses the results of evaluating three conventional image watermarking algorithms for performance and robustness. The findings are based on experiments on a standard LENA image and thus a comparative analys...
IJES AT | Aug-Sep 2013 170 Available online @ http://www.ijesat.org Abstract Video Steganography is a method of hiding data into a carrying Video file. This data can be text, audio, image or a video itself. The video based Steganography is better than the other existing methods because of its high data security and it can accommodate large amount of secret data. The Discrete Wavelet Transform...
Data hiding method based on steganography improving secret image invisibility through replacing Least Significant Bit: LSB with run-length coded Image is proposed. Although, the proposed method is based on Discrete Wavelet Transformation: DWT, run-length coded secrete image is embedded in the LSB of the high frequency component before reconstruction of the image for opening to the public for im...
Steganography is a concept of hiding or concealing data in a cover object while the sender and receiver are able to communicate within themselves. The security of data has been prime concern for the people from past and many research works are still going to find out convenient methods to safeguard the communication between people. Intruder can easily detect the information in the links as inte...
