Enhanced Digital Image Hiding Technique Using Integer Wavelet Transform
The information hiding technique used in our proposed method depends on the biometric features of the image, one of the highly accurate features is the skin color feature that we used in this research. The progress of digital data information increases the need to secure our information and protect the confidingly of them. For that reason, steganography is one of these technologies as art to conceal data within data. Here secret data are hidden in a selected cropped skin region. Before stashed secret message first order Integer Wavelet Transform (IWT) transfer the skin region into four sub-bands (cA, cH, cV, and cD), Pixel Value Differencing (PVD) technique is used to stash the secret information into the cropped region. This process continues until all secret bits are stashed in the selected skin region. Inverse IWT is implemented and merging the cropped region to the cover image to produce stego image. This study shows that the enhancement image concealing method gives a high performance in capacity, invisibility, undetectability, and good MSE & PSNR values.
