Abstract—Reversible data hiding is a technique that extracts
secret data exactly and recovers the cover image completely.
Many reversible data hiding schemes have been proposed in the
literature for various goals. However, many drawbacks are
discovered in these schemes, which are low visual quality,
limited embedding capacity and a large size of the location map.
In this paper, we propose a new reversible data hiding scheme
using pixel order exchange to enhance the embedding capacity
and the visual quality of the stego image. In addition, the size of
the location map in our proposed scheme is very small. In the
proposed scheme, the cover image is processed first. Then, the
order of pixels in a pair is exchanged to embed secret data,
while guaranteeing only a small distortion of the stego image.
Our experimental results indicated that the proposed scheme
provides larger embedding capacity and better image quality
than some previous schemes.
Index Terms—Reversible data hiding, pixel order exchange,
good image quality, high embedding capacity.
