hi,
this is dommati durga prasad pursuing my msc in telecommunications as i want to do my project on the topic of implementation of video steganography using LSB technique in MATLAB where i need to implement like vedios consisting of number of image frame for each image frame i need to hide data and show the output results can i know about it and can i get coding of that particular topic and its documentation.
your regards
domati durga prasad

Stego Machine Video Steganography using Modified LSB Algorithm



I. INTRODUCTION

STEGANOGRAPHY is an ancient art of conveying
messages in a secret way that only the receiver knows the
existence of message. The subject of steganography has been
brought into the limelight by several intelligence agencies and
the news media in recent times. Apart from using state of the
art, communication technologies and media, the agencies are
using cryptography as well as steganography to a ....etc

STEGANALYSIS OF LSB INSERTION METHOD IN UNCOMMPRESSED
IMAGES USING MATLAB


ABSTRACT
In this paper we have explained a steganalytic tool
to detect the presence of hidden message in LSB
steganography. It is process of hiding secret
information in a cover image. Here we have used
LSB insertion method using discrete algorithms.
Steganographic programs use the Least
Significant Bit (LSB) embedding as the method of
choice for message hiding 24-bit, 8-bit color
images and graysca ....etc

Abstract:
This paper introduces a new steganographic technique for secret data communication based on Public Key Digital Image steganography by combining public key cryptography with Digital Image Steganography. The proposed scheme employs RSA algorithm with 1024 bits key size for secret data encryption before inserting it into cover image and F5 steganographic technique to hide the encrypted message inside the cover image imperceptibly. The F5 algorithm embeds the message into randomly chosen Discrete Courier Transform (DCT) coefficients. By ....etc

Abstract

In this paper, a data hiding scheme by simple LSB substitution is proposed. By applying an optimal pixel adjustment process to the stego-image obtained by the simple LSB substitution method, the image quality of the stego-image can be greatly improved with low extra computational complexity. The worst case mean-square-error between the stego-image and the cover-image is derived. Experimental results show that the stego-image is visually indistinguishable from the original cover-image. The obtained results also show a ....etc
