Abstract

This paper presents a steganography method based on an embedded zerotree wavelet compression scheme and bit-plane complexity segmentation steganography. The proposed steganography enables us to use lossy compressed images as dummy files in bit-plane-based steganographic algorithms. Large embedding rates of around 25% of the compressed image size were achieved with little noticeable degradation in image quality.
