Reversible data hiding has drawn lots of interest in the last a few years. With reversibility, original media can be recovered without any distortion from the marked media after the embedded data has been extracted. In this paper, we present a new scheme which utilizes the wavelet transform and better exploited large variance of wavelet coefficient differences to achieve high capacity and imperceptibility. With the particularity of minor changes in the wavelet coefficients after embedding data, low visual distortion can therefore be obtained in the marked image. Furthermore, an extraordinary attribute of our scheme is that the use of embedding level differs greatly from previous schemes. Experimental results showed that the performance our scheme outperforms the state-of-the-art reversible data hiding schemes.
