Advanced wavelet based steganography for colored images

In this paper, we present a novel method to embedding secret message in the cover-image. The basic concept of the proposed method is by simple Least Significant Bit (LSB) substitution. We propose a steganography method that applies a technique to embedding a wavelet compressed secret message within the Least Significant Bit (LSB) of the cover image pixels in a specific pattern. The proposed method results in increasing the secret message capacity and security level. The secret message won't be visible after embedding and can be extracted later. The quality of the resulting secret message, the secret message capacity and the security level of the proposed method are calculated and compared to the method researched by F.AL-Hunaity et al.
