DRM and Threat Analysis

Posted by michael on from the logic-bomb dept.

miladus writes "A timely and concise intervention by Ed Felten on the topic of DRM and the models used (or not used) to represent the threats to defeat. In brief, 2 models, one based on the potential of large scale redistribution of copyrighted files implying defeat of DRM if one user succeeds in bringing file inquestion to P2P network; the other, refers to the majority of users who would casually copy files. The implications of the schematization are most interesting because they explain some the logic behind the often confused and confusing rhetoric of DRM advocates and the necessity for rational grounding for technologies."

  1. If you can't beat them accept the threat model? by Phigrin · · Score: 5, Interesting
    I don't know if saying that the adoption of a threat model isn't just a nice way of saying that you have to accept what you cannot change. The problem of napsterisation, is more complex than that.

    It would be far better to approach this problem on a social rather than a technical security basis.

    I would perhaps like to see a model where you license a song for life. Something along the lines of paying $1.50 for a song and you get a digital certificate that licences you to own the song, no matter where you got it from.

    That would mean that I could get the song quickly from my buddy down the road, and while that is downloading via the loacal bandwidth I could log on to BMI, Sony or whoever (The RIAA homepage!?!?), and pay my royalties.

    No wait, I could just log on to the artist's homepage and pay the $.50 directly to him/her/them!!!

  2. Threat Model by Anonymous Coward · · Score: 5, Interesting

    There's another threat model, it's the immortal music. The RIAA is very upset that CD's last so much longer than LPs. They've tried to block the resale of used CDs. With DRM, they can go back to the old mortal music model. P2P is just the scape goat. Funny how much the casual model sounds like fair use.

    Until the time arrives when DRM will be built" into every speaker you buy and the construction of paper sheets with attached magnets and coils falls under the DMCA or EU-DMCA or whatever.

    Sounds silly?

    Intel is on the way to integrate DRM into monitors so that you can't intercept the signal and record it (e.g. a movie). It's called HDCP -
    High-bandwidth Digital Content Protection.
