| Abstract(in English) | Contents management technologies like the digital watermark and the fingerprint are proposed along with increasing of digital contents of music and pictures. However, In recent year illegal network deliveries with the file exchange software causes a serious problem such as copyright infringements and declining CD sales. In order to solve this problem, (for example, a digtal contents downloaded on the network are identified.etc) the method of applying content management technology to DRM(Digital Rights Management) technology is paid to attention. An audio fingerprint is a compact representation of the perceptually relevant parts of audiocontent. A suitable audio fingerprint can be used to identify audio files, even if they are severely degraded due to compression or other types of signalprocessing operations. We achieved a high-speed FP system on FPGA by improving the audio fingerprint algorithm. In the evaluation of the processing time, about 5.1 times the performance were obtained compared with processing with software. |
