英文摘要	Recently, Zhang [1] proposed a reversible data hiding algorithm for encrypted image, which can reversibly embed data into encrypted image without knowing the original image content. However, in data extraction of this algorithm, the error-rate is large especially for high capacity case. In this paper, to remedy the above problem, an improved method is presented. By our improvement, the error-rate is significantly decreased and the visual quality of the decrypted marked image is enhanced as well. ? 2013 Springer-Verlag.; EI; 0
