Sony's New DRM Technique

Posted by Zonk on from the no-reburning dept.

skochak writes "Sony has introduced a new DRM scheme. You can burn a CD-R from the original once, but you can't re-burn from that first copy." From the article: "The concept is known as 'sterile burning.' And in the eyes of Sony BMG executives, the initiative is central to the industry's efforts to curb casual CD burning. 'The casual piracy, the school yard piracy, is a huge issue for us...Two-thirds of all piracy comes from ripping and burning CDs, which is why making the CD a secure format is of the utmost importance.'"

    As Cory Doctorow put it (in his talk to the Microsoft Research group to be found here):
    ... Cryptography - secret writing - is the practice of keeping secrets. It involves three parties: a sender, a receiver and an attacker [...]. We usually call these people Alice, Bob and Carol. [... A few explanations of cipher, ciphertext and key] In DRM, the attacker is *also the recipient*. It's not Alice and Bob and Carol, it's just Alice and Bob. So Alice has to provide Bob - the attacker - with the key, the cipher and the ciphertext. Hilarity ensues.
