A Multipurpose Wavelet-based Image Watermarking

摘要

To address copyright protection and content authentication, researchers have proposed various digital watermarking methods. In this paper, an improved, multipurpose method is proposed where the authentication watermark and the robust watermark are embedded in the wavelet transform domain. Through a series of experiment, supportive evidence is provided to demonstrate the proposed method being effective in image authentication and pre-empting image processing attacks.
