    Abstract: Distortion-free data embedding is a
    technique which can assure that not only the secret data
    is correctly extracted but also the cover media is
    recovered without any distortion after secret data is
    extracted completely. Because of these advantages, this
    technique attracts the attention of many researchers. In
    this paper, a new distortion-free data embedding scheme
    for high dynamic range (HDR) images is proposed. By
    depending on Cartesian product, this scheme can obtain
    higher embedding capacity while maintaining the
    exactly identical cover image and stego image when
    using the tone mapping algorithms. In experimental
    results, the proposed scheme is superior to Yu et al.’s
    scheme in regard to the embedding rate⎯an average
    embedding rate of 0.1355 bpp compared with Yu et al.’s
    scheme (0.1270 bpp).
