HIGH CAPACITY,LOSSLESS,SECURE IMAGE STEGANOGRAPHY USING WAVELETS



IMAGE STEGANOGRAPHY

Steganography means COVERED WRITING .

It s a concealed communication

Image steganography is the technique hiding a payload (message) is hided
inside cover image (carrier),to get a stego-image.

Cover image is not statistically changed.

The modern example of steganography is a microdot.

COMPOUND WAVELETS: WAVELETS FOR SPEECH RECOGNITION



INTRODUCTION
The wavelet transform has become a popular tool for
image and speech processing, pitch
detection and speech recognition in previous work

The wavelet transform (WT) has the best features of narrow
band and wide band analysis within one transform.
The WT of a speech signal produces fine time resolution
at high frequencies and fine frequency resoluti ....etc

speech compression using haar wavelets using matlab

ABSTRACT

With the growth of the multimedia and cellular technology over the past decades, the demand for digital information increases dramatically. This enormous demand poses difficulties for the current technology to handle speech compression. One approach to overcome this problem is to compress the information by removing the redundancies present in it. This is a lossy compression scheme that is often used to compress information such as speech signals. This paper presents a new lossy alg ....etc

ABSTRACT
Wavelet-based image coders like the JPEG2000 standard
are the state of the art in image compression. Unlike traditional
image coders, however, their performance depends
to a large degree on the choice of a good wavelet. Most
wavelet-based ....etc

Abstract
The biometric person authentication technique based on the pattern of the human iris is well suited for application to any access control system requiring a high level of security. Iris technology has been applied to person verification and identification. This thesis examines
1) Comparitive study of biometric security techniques such as fingerprint, voice, facial, retina and iris.
2) An algorithm for iris recognition system, which is composed of ir ....etc

steganography using wavelets neural network

Abstract

In today s era the most important and valuable
thing in the world is information. You can exploit a person
or organization if someone uses their secret information
against them. There are many ways to secure the data
from being misuse, one of them is cryptography.
Cryptography is the technique for coding the message so
that it cannot be understood. The next milestone is the
Steganography technique which took the security to whole
new ....etc
