摘要：

Although many data hiding schemes have been proposed in the frequency domain, the tradeoff between hiding capacity and image quality is still an existing problem to be solved. In this paper, we proposed a novel reversible data hiding scheme based on the Haar discrete wavelet transform (DWT) and interleaving-prediction method. First, a one-level Haar discrete wavelet transform (DWT) is implemented to the cover image, and four sub-bands, LL , aEuro,HL , aEuro,LH andaEuro,HH, are obtained. Sub-bands HL, LH aEuro,andaEuro,HH are chosen for embedding. After that, the wavelet coefficients of the chosen sub-bands are zig-zag scanned and two adjacent coefficients are used for prediction. The secret data is embedded in the prediction errors, which is the difference between the original value and the predicted value of the wavelet coefficients. The experimental results showed that our scheme has good performance compared with other existing reversible data hiding schemes.
