Microsoft's Janus DRM Software Officially Unveiled 570

hype7 writes "News.com.com is reporting the official unveiling of Microsoft's new DRM system, internally dubbed 'Janus'. Interestingly enough, a wide variety of companies including AOL, Dell, Disney, Napster and Freescale, a subsidiary of Motorola, have all signed on to the technology. Whilst some content providers and producers are keen, it remains to be seen what consumers will think - 'the new digital rights management tools include features that would protect content that is streamed around a home network, or even block data pathways potentially deemed 'unsafe,' such as the traditional analog outputs on a high-definition TV set. That's a feature that has been sought by movie studios in advance of the move to digital television.' I love the quotes from the MS rep - 'This release of technology really enables all kinds of new scenarios that are emerging now,' said Jason Reindorp, a group manager in Microsoft's Windows digital media unit. 'We're taking quite a holistic view.' It's good to see Microsoft taking a holistic view of preventing the consumer doing what they want with their paid for content, and protecting us from unsafe data pathways."

    This was previously discussed on Slashdot [slashdot.org] a month ago.

    There appear to be something called Janus Quadrifrons which indeed had "faces-inclined-in-many-directions".
    Read more about it here [wikipedia.org].

    Over-the-air HDTV is a done deal; it's unencrypted with the broadcast flag to "control" copying. No one is suggesting using Janus for over-the-air HDTV broadcasts.

    The application for Janus is mentioned in the article: playing rented music on portable players.

    when NOTHING will work on any electronic device without a conglomerate corporation's device allowing it to go through
    then save your old hardware. i have an older portable minidisc player/recorder with a mic input. sony took the mic input off its new models because people used them to bootleg.

    Check out LinuxBIOS [linuxbios.org]. While it could probably be blocked by manufacturers, it's interesting enough. And there will allways be some small manufacturers that will sell you DRM-free hardware, probably the same ones that are selling 'pirated' brand rippoff, but still working, hardware today. Think Chinese factories. They don't have anything to gain from making you abide by some fucked up copyright law, and they're allready showing their disregard of it now. Actually, this kind of DRM would be illegal in a lot of countries that still have fair use in place. So, I'm not too worried. Sure, the average user will probably be locked up by their own hardware, but eventually, we'll have something like open hardware [wikipedia.org] in place, for those that want it.

    > Am I way off base with my thinking in this

    Sadly, yes.

    A legal "right" basically says "you can't be prosecuted just for doing this". Note the "just" - that's important, as obviously if you committed a crime in the course of doing it you could be prosecuted for that.

    It *doesn't* say that you have to be physically able to do it. Thus, right now, you have the right to drive a Rolls-Royce, because you wouldn't be prosecuted just for doing so. You cannot however demand one without paying, because the right doesn't say that you have to be physically able to do it. Likewise, you can't steal one, because then you could be prosecuted for stealing the car (which is not the same as prosecuting you for just driving it)

    So the fact that copyright law doesn't give anyone the "right" to restrict usage doesn't mean they can't do it. You don't need an explicit right to do everything.

    And the fact that you have the "right" to fair use, sadly, has been interpreted by a court is meaning it's OK for you not to do it. Legally, under the DMCA, you *can* break DRM to make fair use. But you *can't* distribute anti-DRM tools, so you have to work out how to do it yourself; and if you can't do that, that counts as "not doing it physically" so it doesn't legally deprive you of your right..

    Mod this parent up he brings up a good point. anytime I buy a game I usually go online and get the no cd crack anyway just so I can put the cd away and not worry about scratching it. He just takes it one step further.

    Copyright law (in the U.S.) does not give the copyright holder any say over how their work is used by an individual who legally possesses a copy. Copyright law only gives power to the copyright holder over making and distributing copies, and (where appropriate) publicly performing the work. If you legally buy a copy of a work that is available to any member of the public willing to pay, you can take that copy home and read it, listen to it, watch it, burn it (set it on fire, not burn it to a CD), wallpaper your room with it, wipe your ass with it, or whatever else you see fit. (As long as that use isn't illegal in other senses, e.g. you may not beat someone to death with it.)

    The DMCA (and now various DRM schemes) effectively give the copyright holder a right they never had before: the right to dictate how you can use that work in the privacy of your own home. Copyright law doesn't say that Disney can force you to only watch their Aladdin DVD using software that Disney has approved... but the DMCA does. Since the DVD CCA controls its DVD decryption software as a trade secret, and only licenses it to DVD player-manufacturing companies who paid them a fee, AND since (thanks to the DMCA) it is illegal for a customer to reverse-engineer that DVD player in order to find out how the decryption works and write their own software... well, you get the picture.

    The solution to this problem is left as an exercise for the reader.

    It's very unlikely that someone will find a way to beat public key and AES encryption.

    That's not true... you don't need to "break the encryption" because the very nature of DRM encryption is that the client is doing the decryption himself. At some level you have to trust the client not to reveal the key to the user. All a hacker needs to do is figure out how it's encrypted and what the key is. The key is on your computer. You don't need to "break" anything.

    - grab the data when it is in the clear. This is what the iTunes crackers do.

    That's what qtFairUse did - snagged the data as it went through quicktime. But PlayFair is different and better - dvdJohn figured out how iTunes generates the key (from HD serial number and stuff) and that's the trick. No breaking of encryption is involved.

    I think what you're failing to understand is that all DRM mechanisms that have so far been conceived rely on the client at some level to hide the key or the mechanism of the encryption. As a programmer (but not a encryption expert) it is impossible for me to envision any other kind of DRM besides "security through obscurity" and that's why I agree with the grandparent that every popular DRM format will be cracked in time.

    Never mind that ANYTHING you can see or hear can be recorded, DRM or not, from an analog signal using advanced technology such as "sound cards" or even "tape recorders".

    I've never ever heard anyone talk about fair use outside of Slashdot, period. For most people it just isn't a big deal.

    For the average person, it's not currently a big deal, but try talking to some librarians or educators. It's a big deal to them. Read the CETUS Fair Use Pamphlet [cetus.org] for the perspective of universities on fair use.

    However, in the future, the loss of fair use rights will be a big deal to the average person. The right of first sale is one of such right that people are going to miss when they can no longer sell their old books, music, and movies and when stores that can legally sell used versions exist. It's worth remembering that consumers have already shown their dislike of digital formats that remove some of their fair use rights--remember how consumers rejected of the DivX movie disk format in favor of DVDs.

    It makes me wonder if the whole system of copyright is rather broken, to be frank. But I don't know of a better way, so I can't really criticize too much.

    Law professor Jessica Litman offers some interesting alternatives to the current economic and legal copyright system in her book Digital Copyright.

    Why would the government, or anyone else, have any interest in forcing me to DRM my own web page?

    They have an interest in forcing you to cryptographically sign it so that they know whom to hold accountable if the page contains illegal material.

    "But the new digital rights management tools also include features that would protect content that is streamed around a home network, or even block data pathways potentially deemed "unsafe," such as the traditional analog outputs and cathode ray tube on a high-definition TV set. That's a feature that has been sought by movie studios in advance of the move to digital television."

    I think the above might work as advertised. Anything less than that is a total farce, but we all know it already.

    Just in case you were serious...

    Digital TV has been mandated by the U.S. Congress. All television stations must convert to digital format or go off the air. Stations must also support the current analog format until 2006 or until 85% of households have digital equipment.

    The Federal Communications Commission recently voted to require electronics manufacturers to include digital tuners in all new television sets by 2007 -- the agency's strongest action to speed the federally required conversion to digital television.

    Hence, everyone who buys a television after 2007 will necessarily contribute to the 85% required before analog is ditched.

    Theoretically, it is "possible" that everyone will stop buying new equipment, but realistically, the government has "mandated" digital content. Perhaps he should have said "effectively mandated".

    Way wrong. The Titanic was compartmentalized, however the long gash in the hull flooded too many compartments.

    And that's not the whole story, either. The compartments didn't reach high enough in the ship. It didn't matter that the compartments had watertight bulkheads, because as each breached compartment filled, it spilled over the tops of the bulkheads into the next compartment.

An authority is a person who can tell you more about something than you really care to know.
