Abstract

Reversible data embedding has drawn lots of interest recently, specially in the field of protection for cultural heritage and medical image. Being reversible, the original digital content can be completely restored. This paper uses Tian's algorithm of difference expansion as reversible watermarking scheme for the protection of cultural heritage and medical image. Lifting together with channel coding is used to increase the detection performance of extracted watermark bits. Experimental results and performance comparison with other reversible data hiding schemes are presented to demonstrate the validity of the proposed algorithm.
