Abstract

This paper proposes a novel asymmetric watermarking scheme. In the proposed scheme, the asymmetric detection watermark is obtained by performing a fractional discrete cosine transform (FDCT) to a primitive watermark. The watermark for embedding is part of the primitive watermark, and it is embedded in the FDCT domain. The asymmetric detection procedure is performed using a correlation test. The theory analysis and simulation results demonstrate that the proposed scheme can provide the minimum security and reliable asymmetric watermark detections.

Keywords: asymmetric watermarking FDCT public attack.
