| Abstract: | In many printer and publishing applications, it is desirable to embed data in halftone images for copyright and authentication purposes. A novel data hiding algorithm for halftone images was proposed. The digital watermarking was embedded by DCT data classification method. Experiments showed that this algorithm is robust for printing and scanning. |
