Abstract A blind wavelet-based watermarking algorithm with robust for image cropping is proposed. The original image is transformed using wavelet transform and the watermarks are embedded in two selected subbands according to neighboring symbol’s mean value and odd-even adjugement rule. This is a blind watermarking algorithm which can confirm the copyright without original image. Experimental results and attack analysis show that the watermark algorithm proposed in this paper is transparent and robust to various attacks. In particular, the robustness of wavelet domain watermarking to cropping attack and incorporating attacks is increased.

Key words： Digital watermark Wavelet transform Neighboring symbol’s mean value Odd-even adjugement rule
