Submission + - “Dirty” MP3 Files Are A Back Door Into ( 1

Phurge writes: Hidden in purchased music files from popular stores such as Apple and Walmart is information to identify the buyer and/or the transaction. You won’t find it disclosed in their published terms of use. It’s nowhere in their support documentation. There’s no mention in the digital receipt. Consumers are largely oblivious to this, but it could have future ramifications as the music industry takes another stab at locking down music files.

When personal libraries are stored in the cloud, it becomes possible to retrieve this personal data and match it to a user identity. If the match is successful the song plays, but if not, access can be blocked through a network DRM system such as the one Lala patented (which is now owned by Apple).
