    Abstract: This paper proposes a novel data hiding framework based on image hashing
    strategy. First, the best-matching blocks for each cover image block are searched in the
    existing database, which can be generated by the codebook of vector quantization technique.
    Then, a dictionary consisting of different versions for each cover block is constructed by
    a set of content-preserving manipulations, and each version is assigned with a unique
    binary representation. According to the secret data hidden for each block, corresponding
    versions of the block in the dictionary are chosen to substitute the cover block and form the
    stego image. Due to the properties of robustness and anti-collision of image hashing, the
    secret data can be extracted correctly by comparing the stego block with the blocks in the
    reconstructed dictionary. The experimental results show the effectiveness and
    exibility
    of the proposed framework.
