This paper proposes a novel data hiding scheme with high capacity for binary images, including document images, halftone images, scanned figures, text and signatures. In our scheme, the embedding efficiency and the placement of embedding changes are considered simultaneously. Given an M×N image block, the upper bound of the amount of bits that can be embedded of the scheme is nlog2((M×N)/n + 1) by...
In this paper a novel data hiding scheme for MPEG compressed audio is proposed. It exploits wet paper codes as the communication channel and hides data directly in the MPEG audio bit stream by modifying the MPEG audio quantization process. It is applicable to all three layers of MPEG audio. Experimental results show that the proposed method is sustainable against transcoding and re-encoding without...
