Abstract
Secured data transmission over computer networks can be achieved through steganography. In specific, Image Steganography entails the opportunity of hide any secret information into images. This paper presents the implementation of two image steganographic techniques in MATLAB. The first is a filter method to embed text information into image and new methods have been demonstrated to increase the information embedding capacity in the same domain. The second method is the wavelet transform method which proves to be more secured than any other method of image steganography.
