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.
