Abstract
Reversible data hiding is a technique that extractssecret data exactly and recovers the cover image completely.Many reversible data hiding schemes have been proposed in theliterature for various goals. However, many drawbacks arediscovered 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 schemeusing pixel order exchange to enhance the embedding capacityand the visual quality of the stego image. In addition, the size ofthe location map in our proposed scheme is very small. In theproposed scheme, the cover image is processed first. Then, theorder 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 schemeprovides larger embedding capacity and better image qualitythan some previous schemes.
