Digital watermark can be used for image ownership verification or authentication. In this paper, we propose a new image authentication plan concentrating on its security performance. Digital watermark is first turbo coded, scaled and then processed in wavelet domain. To enhance security level, public key cryptosystem is utilized to replace traditional watermark key. Simulation results are finally given by experiment.
