| Abstract(in English) | Recently, illegal spread of digital contents via network becomes a serious problem. In order to solve this problem, digital watermarking has been proposed which shows copyright information. Digital watermarking is the technique to embed copyright information that people can not recognize into digital contents. However, digital watermark detection by software is too slow and it can not catch illegal audio files exchanged over network. In this paper, we propose a high speed digital watermark detection scheme by implementing parallel detector on a FPGA chip. Since it is difficult to detect many watermarks at high speed by software, we use hardware to detect many watermarks at high speed by implementing the detection circuit of digital watermarking in parallel. Estimation results show that the proposed hardware scheme is 148 times as fast as software. |
