Multiple digital watermarking technique based on wavelet transform

This paper proposes a multiple digital watermarking scheme based on wavelet transform. It embeds a robust watermark and a fragile watermark after the holistic wavelet transform of the image. This scheme can ensure both the copyright protection and the integrity of digital production. Moreover, it does not need the initial host image in watermarking extraction. The technique provides an integrated and secure protection scheme for digital production. Our simulation results testify the robustness, security and the proving ability of tamper-proofing of this technique.
