Title
A secure data hiding method based on preservation of saturated pixels
Abstract
Zhang and Wang in 2007 proposed an exploring the modification of embedding directions (EMD) method for which n pixels are used as an embedding unit, and a digit in based 2n+1 can be concealed by modifying a pixel value a grayscale at most. In case the overflow or underflow problems occur, EMD adds or subtracts one of the saturated pixels in the same pixel group by one and re-embeds the digit. However, if the number of saturated pixels is considerable, the modification of the saturated pixels may result in a critical vulnerability to the LSB-based steganalyzers. This paper proposes a method to leave those saturated pixels untouched and embeds only those non-saturated ones. Because no saturated pixels are modified, the stego image is insensitive to the detection by the LSB-based steganalyzers. The experimental results reveal that the proposed method is more robust to the LSB-based steganalyzers than the original EMD method when the number of saturated pixels is considerable.
