Abstract: Information hiding is a technique that embeds secret data in digital
media for using in a variety of applications, including ownership protection,
authentication, access control, annotation and so on. In this paper, we propose
an information hiding scheme based on quantization-based embedding technique to
conceal information in gray-scale image. The proposed scheme was tested with a
variety of gray images. According to the experimental results, hidden
information can be extracted correctly and quickly from the stego image. In
addition, the stego image has only a little distortion compared with the cover
image. The proposed scheme can not only hide a large amount of information in
the cover image, but can also repair the stego image such that the repaired
image is almost the same as the cover image.
