Abstract. This paper presents two main results. The first is a new approach to steganography in which data is encoded in correlations among the pixels in an image. Almost all prev...
This paper presents a novel Mod-4 steganographic method in discrete cosine transform (DCT) domain. A group of 2?2 quantized DCT coefficients (GQC) is selected as the valid embeddi...
This paper investigates the possibilities of steganographically embedding information in the \noise" created by automatic translation of natural language documents. Because th...
