Light Weight Cryptography Based Digital Images Stegnography

Steganography is an ability of concealing information inside the cover in such a way it looks like simple cover though it has concealed information. There are many techniques to carry out steganography on electronic media, most especially audio and image files. In this method, we proposed a high secure steganography scheme hiding the image and text into cover image with different combination of Discrete Wavelet Transform light lightweight cryptography algorithms (DWT). Experimental results and case study provided the stego-image with perceptual invisibility, high security and certain robustness. The aim of this project is to propose a high-capacity image steganography technique that uses pixel mapping method in integer wavelet domain with acceptable levels of imperceptibility and distortion in the cover lightweight cryptography algorithms image and high level of overall security. This solution is independent of the nature of the data to be hidden and produces a stego image with minimum degradation.
