EFF: DRM-free iTunes files carry 'more than just names and e-mail addresses'

EFF IN THE NEWS
July 18, 2007

The morning during/after the launch of iTunes Plus yesterday was a rough one for the iTunes Store, but users were generally pleased with their newfound freedom. Or so they thought...

Well, the Electronic Frontier Foundation picked up on this newfound information about the embedded personal data and investigated a bit further. As it turns out, the DRM-free AAC files from iTunes contain more than just names and e-mail addresses. While they decoded some DRM-free AAC files to PCM/WAV and found that there isn't a watermark in the compressed audio signal, there are "surprisingly huge differences" in the encoded files. "Much bigger differences than just different tags, or even different signed/encrypted tags," the EFF wrote.
