Abstract

For some special data transmission situations, data must be transmitted safely and reliably. In this paper, a data embedding algorithm is proposed based on difference expansion. The digital image is a carrier of data transmission, according to the principle of difference expansion, data is embedded to digital image and sent to the receiver that is used to restore data using reversible data embedding method. Comparing with other algorithms, the experimental results show that this algorithm has a higher data embedding ratio and a lower distortion ratio.
