Secret data delivery is a most important activity in the modern life. Steganography technique uses a cover medium to carry secret data and deliver it to right receivers over public computer networks. Because a stego medium is easier to cheat an unexpected user's observation, Steganography technique is more suitable for delivering secret data. Histogram adjustment is a good way for concealing secret data into a cover image with small distortion. Luo et al. use the pixel interpolation technique and histogram shifting to conceal secret data into a grayscale image. Visual quality and embedding capacity are two most important factors for designing a data hiding technique. The performance of Luo et al.'s method in terms of embedding capacity can be further improved. The proposed method is to increase the height of peak in dierence histogram as many as possible. A segmentation strategy is adopted for narrowing down the range of dierence between a pixel and a pseudo pixel.
