In this paper, a novel watermarking technique for image authentication is proposed. This technique operates in the wavelet domain and makes use of semi-fragile watermarks for achieving better robustness. The image is first transformed into the wavelet domain and the relations between neighboring coefficients are utilized to authenticate the integrity of the image content. By carefully designing the processes of feature extraction and watermark embedding, the proposed method is able to identify… CONTINUE READING
