چکیده
In today’s highly digitalized world maintaining the secrecy of the secret data is a vital problem. Steganography is an emerging area which may be used for secure transmission of the digital data. It is the art and science of embedding data into different covers such that the data embedded is imperceptible. The covers that can be used cover all forms of digital multimedia object namely text, image, audio and video. This paper proposes a novel multimedia based steganography technique for an un-compressed movie. This proposed work hides the data both in audio and video signal part of the movie. In video part data hiding operations are executed entirely in the discrete integer wavelet domain by converting the gray level version of each frame of the video in to transform domain using discrete integer wavelet technique through 2-D lifting scheme through Haar lifted wavelet. For providing an imperceptible stego-frame/stego-video for human vision, a novel image based steganographic approach

A Robust Image Steganography Method Using PMM in Bit Plane Domain
Steganography is the art and science information in an appropriate cover carrier like image, text, audio and video media. In this work the authors propose a new image based steganographic method for hiding information within the complex bit planes of the image. After slicing into bit planes the cover image is analyzed to extract the most complex planes in decreasing order based on their bit pla...

متن کاملAn Fft Based Signaling Scheme for Multimedia Steganography
In this paper, we present an e cient FFT based signaling scheme for Multimedia Steganography. The use of FFT permits the use of signal sets of large dimensions without increasing the computational complexity drastically. This is achieved by generating the maximally separable points of the signal constellation in such a way that detection is implemented through an FFT based cyclic correlation. I...
