    摘要: Data hiding involves conveying secret messages under the cover digital media
    such as images. It is the science of concealed communication. The term hiding can
    refer to keeping the very existence of the embedded messages imperceptible. Intuitively,
    a technique that introduces less embedding distortion to the cover object will generally
    cause changes that are more difficult to detect, and will therefore provide more security.
    In this paper, we propose a data hiding method based on VQ compressed images. To improve
    communication security, Hamming codes are applied for increasing the embedding
    efficiency (the number of bits embedded per embedding change). Experimental results
    indicate that our proposed scheme provides improved steganographic security and better
    image quality compared with existing schemes based on VQ compressed images.
