Robust Steganographic Algorithm based on Wavelet Transform

Abstract

This paper proposes a new robust algorithm for hiding information in the visual information of images. Our robust version (RV) supports hiding data in 40×40 pixel black and white image and even after resizing and jpeg transform, around 80% of the original watermark can be recovered. Our dimension version (DV) increases the amount of data that may be hidden, up to 75% of LSB steganography but offers a high level of imperceptibility by hiding data inside the wavelet coefficients.
