In recent year illegal music distribution via network with the file exchange software in recent years becomes a serious problem such as copyright infringements and CD sales number decreases. Thus the technique for using the contents management technology for DRM (digital copyright management) technology is paid to attention as the measures. (For instance, contents that flow on the network are identified. )Some identification methods like the digital watermark and the fingerprint, etc. are proposed as the number of music in recent years increases.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.
It was thought that it was not possible to adjust to the DRM system only by jast implement the algorithm hardware in this research.
Therefore, I achieved a more high-speed fingerprint system on FPGA by using the technique of the loop unrolling of the computing unit and the parallel processing that used the pipeline register.
In the evaluation of the processing time, about 10.6 times the performance were obtained compared with processing with software. |
