Macrovision's SAFEAUDIO V3
Music Industry News - as it happens
Source: Mi2N - May 28, 2002
Net newsgroups and websites have recently been circulating news of users
having circumvented Sony's Key2Audio audio CD copy protection by,
"scribbling around the rim of certain copy protected discs with a felt-tip
marker to intentionally corrupt the data indexes of the CDs," says
Macrovision, which makes and sells copy protection and rights management
technologies for audio and video products.
The postings claim a felt-tip - or even a piece of tape - can be used to
corrupt the index and get around the copy protection feature, allowing the
user to copy the music tracks to a hard drive, it says, gong on that the
same postings suggest other copy protection products can be circumvented
using the same hacking technique.
But, says Macrovision, its SAFEAUDIO V3 is, "resistant to this hack approach
because we have implemented a tunable multi-layer security solution, which
is based upon multiple patent-pending technologies.
It adds: "It should be noted that using ink of any sort on the playing
surface of the CD can cause loss of the entire contents of the CD.
Introducing ink or foreign materials on the playing surface of a CD can also
damage the CD player reading device. Consumers should be aware that any
damaged media or corrupted media files caused by this hack may void any
warranties for such media, the content contained thereon, or the playback or
"Attempted use of this hack is also likely to prevent access to
entertainment content (such as videos, photographs, lyrics, pre- compressed
audio tracks for export to PCs and portable players, etc.) stored on the
"second session" of multi-session CDs and protected by Macrovision's
SAFEAUTHENTICATE product. Macrovision strongly discourages consumers from
attempting this hack on any CDs enabled by SAFEAUDIO and SAFEAUTHENTICATE."
