Abstract

In this paper, we propose an efficient watermarking technique using adaptive differential energy watermarking (ADEW) and cross binding wavelet tree (CBWT) for copyright protection. The ADEW embeds a secret bit string using the reference threshold with experimental statistics. The proposed method not only takes advantage of the ADEW's error resilience but corrects a secret bit string by using ECC after error occurrence. Experimental results indicated that the proposed method provides better robustness against attacks than the conventional DEW approaches.
