Abstract

In this paper an adaptive, secure and high capacity image steganography algorithm based on Integer Discrete Wavelet Transform is proposed. The algorithm is adaptive as it chooses the optimum value for threshold based on cover image and secret image through an iterative process, using least possible number of DWT coefficients. The experimental results show that the algorithm chooses the optimum value for the variable threshold for the given cover image and secret image and helps in obtaining the best PSNR for the steganography image.
