Abstract |
|
Image steganography is applicable in department of defense, department of police, department of detective investigation and medical field. In image steganography, generally secret image is not hidden, instead of that a key is generated and that key is hidden in the cover image. By using that key the secret image can be extracted from the cover image. Wavelet Transform (WT) is used to hide the key. Wavelet Transform is very robust and secure because nobody can realize information which is hidden and hidden data cannot be lost because of noise or any signal processing operations. Experimental results show very good Peak Signal to Noise Ratio (PSNR), MSE and maximum error which is a measure of security. In this technique the secret image is hidden in the middle bit-planes of the integer wavelet coefficients in high frequency sub-bands. |
