Abstract :
Based on the analysis of previous digital watermarking algorithms for image in two different domains, spatial domain and frequency domain, the paper has put forward a DCT-based digital watermarking algorithm for image, which is not only robust against attacks on watermarking information but also has a larger watermarking capacity than previous DCT-based watermarking algorithms.
