Abstract (in Japanese) (See Japanese page) 
(in English) Recent Internet provides a field activating the distribution of music, while it is also a hotbed of illegal copies. This research aims to realize a legitimate music sharing system easy to use on the Internet, by searching music in network equipments and presenting the license and the billing information to the receivers. Staged LSH in Yang's previous work achieved speed-up to a certain extent, but the database was only 300 songs and the bit error of fingerprints slowed the searching. In this paper, we constructed the database equivalent to ten million songs by random number, and then succeeded in making the searching 70.0 times faster but maintaining the accuracy by using two kinds of external memories and a method tolerating a few bit error.
