In this chapter, the author describes the pixel value correlation-based steganography techniques and maximum pixel value difference-based steganography techniques. The pixel value-based correlation steganography techniques utilize the relationship among the pixel values of a block, whereas the maximum pixel value difference steganography techniques utilize the largest pixel value difference among different pairs of pixels in the block. Although the PSNR values of these techniques are better as compared to the traditional PVD schemes, the hiding capacity is not improved.

Pixel Value Difference

In this chapter a novel data hiding approach by combining Particle Swarm Optimization (PSO) and Pixel Value Difference (PVD) has been proposed. Pixel-Value-Difference (PVD) method of Steganography uses the difference between pixels within an image to hide secret data. The proposed method is a block-based adaptive steganographic approach, which selects M×N block of pixels from cover image and embed secret message within pixels using Pixel-value-difference and LSB substitution method. PSO is used to select most appropriate areas within the image for hiding secret information. Results obtained using the approach show that distortion due to data embedding is negligible. The proposed approach is compared with existing methods in terms of bits per pixel. This method could be applied to hide any digital secret data for secure transfer over internet.
