    Abstract: Steganography is a technique that
    conceals secret data into a cover medium for delivering
    secret data over public computer networks. Reversible
    data hiding schemes not only can achieve secret data
    delivery, but also can restore the cover medium.
    Histogram shifting is one of the most popular reversible
    data hiding techniques. Luo et al. presented a reversible
    data hiding technique that shifts the histogram of
    prediction error. But the embedding payload of Luo et
    al.’s method can further be improved. The proposed
    method uses a difference segmentation strategy and
    pseudo pixel generation to increase the height of peak in
    the prediction error histogram. The experimental
    results show that the embedding payload of the
    proposed method is higher than that of Luo et al.’s
