    Abstract: The reversible image hiding method is one data hiding technique for protecting
    secret data or copyright. The reversible image hiding method can completely
    reconstruct the cover image from the stego-image after the embedded secret data are completely
    extracted. However, many proposed reversible image hiding methods require a
    location map to restore the cover images. Although the location map can be compressed
    by a lossless compression algorithm, it will decrease the embedding capacity and increase
    the computational cost. This paper presents a new type of adjustment reversible image
    hiding method without a location map. The proposed method applies the multiple-base
    notational system to embed the secret data into a cover image with minimal distortion
    and provides several advantages: (1) the location map is not required; (2) the embedding
    capacity can be adjusted according to the user’s practical applications; (3) a high
    embedding capacity with pleasing visual image quality, especially the smooth images, is
    achieved. Furthermore, the experimental results demonstrate that the proposed method
    achieves a higher embedding capacity and satisfactory visual image quality.
