Abstract
En 中文
In 2006, Zhang and Wang developed the EMD (exploiting modification direction) method for embedding secret message into pixels. Their scheme gives a maximum capacity of 1.16 bpp (bits per pixel) when the cover pixel number is 2. However, the embedding capacity rapidly decreases when the selected pixels increase. In addition, the binary data must be converted to a different radix before it is embedded. In this paper, we will propose a binary power data hiding scheme for digital images. According to our analysis, there are four major contributions in this proposed scheme: enhanced embedding data speed, embedded capacity of at least 1 bpp, stego image quality is better than 51 dB when the number of cover image pixels approach to infinity in a pixel group and it can prevent visual attack and RS attack.
