English Abstract
Information hiding techniques have recently become important in a number of application areas.
Digital audio, video, and pictures are Pleasingly furnished with distinguishing but imperceptible marks, which may contain a hidden copyright notice or serial number of even help to prevent unauthorized direct copying.
Military communication systems make increasing use of traffic security techniques which, rather than merely concealing the content of a message using encryption, seek to conceal its sender, its receiver of its very existence.
Similar techniques are used in some mobile phone systems and schemes proposed for digital elections.
Criminals try to use whatever traffic secant properties are provided intentionally or otherwise in the available communication, systems, and police forces try to restrict their use However, many of the techniques proposed in this young and rapidly evolving field can trace their history back to antiquity ; and many of them are surprisingly easy to circumvent This Thesis speaks of a secret-key stenographic system which beds four gray-scale secret images of size (128 x 128) pixels int0 a cover image of size ( 512 x 512) pixeIs, The techniques analyze the cover into its frequency components are wave.et transfer™ -ng Haar Filter as a basis function .on and the new approach Multiwavelet transform using GHM fiber as a basis function.
Multiwavelet transform can be cons.
dared as a development of the scalar wavelet transform since it gives best results in many applications like compression and denoting new approach (Multiwavelet transform) offers a combination of orthogonality, symmetry and compact support, which cannot be achieved by any scalar wavelet basis
