Abstract: | In this paper, two text digital watermarking methods are compared in the context of their robustness performances. A nonlinear watermarking algorithm embeds the watermark into the reordered DCT coefficients of a text image, and utilizes a nonlinear detector to detect the watermark in some attacks. Compared with the classical watermarking algorithm, experimental results show that this nonlinear watermarking algorithm has some potential merits. |
