“…One of the major power of WT compared to the DFT and DCT is its resemblance with HVS which permits the watermark to be embedded in the area that the HVS is recognized as less perceptive to, for example the high resolution detail bands HL, HH and LH [12]. Embedding watermarks in these areas let us to enhance the strenght of our watermark, at small to no other impact on picture quality.…”

“…In Wavelet-based steganographic methods, the cover image is converted into detail and approximation components and they are converted back to cover image [12,13]. Comparatively, wavelet based methods preserves image quality and authenticity and robust against attacks [14]. Swelden proposed using the biorthogonal wavelet based on lifting scheme [15], where the discrete wavelets are polyphase decomposed.…”

In the modern era, concerns about safeguarding the information from attacks are on rise. Here, 2-d lifting wavelet decomposition of a grayscale cover image through Cohen, Daubechies and Feauveau (2,2) lifting wavelet is performed and three secret images are shuffled and embedded in detail coefficients of the transform using approximation coefficients as indicator. Here, a novel Approximate Coefficients Value Indicator methodology is used to shuffle and embed the binary images in detail coefficients. Lossy and lossless steganographic techniques, followed by a lossless compression scheme using Huffman encoding are proposed. In lossy steganographic technique, secret images are embedded in LSB values of high frequency bands of the transform. In lossless technique, high frequency band values are expanded and images are embedded as previous method. Attacks such as Histogram attacks, statistical attacks are performed to check the robustness of the proposed algorithm. MSE and PSNR values are calculated to demonstrate the imperceptibility of the proposed method.
