2018-3-22 · The goal of this paper is to present a highly undetectable audio steganography technique. The novelty of this technique comes from the utilization of voiced frames of cover speech audio signal for embedding the secret message using discrete cosine transform (DCT) approach, along with singular value decomposition (SVD).

2016-12-3 · Broadly speaking there are 4 steps involved in embedding a message using DCT: Divide the image into 8x8 blocks. Transform each block using DCT mathematical operations. Quantitize each DCT block (lossy compression) Embed the message bits from the quantitized coefficients (avoid 0, 1, -1, and the AC) Thats ok, but I am not sure how to extract the ...
