The RIAA are not dumb. That’s for sure. AP reports that court papers filed against a Brooklyn woman fighting efforts to identify her for allegedly sharing nearly 1,000 songs over the Internet, show that “using a surprisingly astute technical procedure, the Recording Industry Association of America examined song files on the woman’s computer and traced their digital fingerprints back to the former Napster file-sharing service, which shut down in 2001 after a court ruled it violated copyright laws”.
The RIAA’s latest court papers describe in unprecedented detail some sophisticated forensic techniques used by its investigators. For example, the industry disclosed its use of a library of digital fingerprints, called “hashes,” that it said can uniquely identify MP3 music files that had been traded on the Napster service as far back as May 2000. By comparing the fingerprints of music files on a person’s computer against its library, the RIAA believes it can determine in some cases whether someone recorded a song from a legally purchased CD or downloaded it from someone else over the Internet. A sobering thought.
