Abstract
Steganography is a technology that is used to conceal the information within some objects such as image, audio or video so that no one can sense the information. Steganography method has several advantages including high hiding capacity and undetectability. The secret content has been hidden into cover image using IWT method. It is difficult to detect the hidden information by Steganalyser since Stego Image and Cover image seems to be similar. High PSNR (Peak Signal to Noise Ratio) value for the extracted image is as same as the secret image. This has been substantiated by comparing techniques which are similar to IWT and the results throws light that the proposed IWT technique is simpler and also gives better PSNR values.
