Microsoft Patents DRM'd Torrents

Anonymous Crobar writes "Microsoft has received a patent for a 'digital rights management scheme for an on-demand distributed streaming system,' or using a P2P network to distribute commercial media content. The patent, #7,639,805, covers a method of individually encrypting each packet with a separate key and allowing users to decrypt differing levels of quality depending on the license that has been purchased."

That's actually pretty clever

[holophrastic]

It's a great way of monetizing uncontrollable distribution channels. Easily allow anyone and their goldfish to distribute large content freely, and effectively charge at the codec level. Certainly solves a good half of the people-steal-everything problem. The patent's still stupid, but the idea's great -- I'd support a two-year patent certainly.

Hahhahahahahahaha, you're serious aren't you? The malware/scammers have been distributing DRM'd WMV files for ages, hoping to make suckers get rooted by their malware or steal their credit cards. Nobody distributes them except retards and others too lazy to check their downloads, this changes nothing at all.

I'd pay, but I want the assurance that Big Content's hands stay off of my media, ESPECIALLY if I payed for the better quality. If I can't duplicate it, play it on my TV or stream it to a laptop/360/iWhatever/wireless projector/blahblahblah then I'm definitely going to pirate it. The biggest issue I have with DRM content is that the model for DRM hasn't gotten past the whole "You can have it, kinda, but its really still ours" mentality, and I'm not counting on codec-levels being the only "DRM" going on here.

1. How is making a copy "stealing?" You are failing to meet a key criterion by not depriving the person from whom you made the copy of whatever you copied. Stealing would be walking into my house and taking my hard drive.
2. This system will fail because nobody will download the restricted media; there is unrestricted media available at no cost. Further, the amount of time needed to extract the secret keys from the restricted codecs is minimal, unless a hardware crypto module is required. I expect that any software implementation will be broken within a week; an implementation using hardware crypto will probably be defeated within a year of its release.

Some of us stopped feeling remorse for the recording and movie industries when we saw how extensive their lies are. Like, the RIAA claiming that Kazaa was killing CD sales, when in reality they had record setting revenues during the height of Kazaa. Or Hollywood accounting. Or the claim that downloading is benefiting violent Mexican gangs. After a decade of claiming that they are suffering financially, I would expect to see RIAA and MPAA member companies all defunct or near bankruptcy, yet in reality these companies are among the wealthiest and most powerful corporations in the world.

The patent is NOT about distributing encrypted files, that is just one requirement of the process. RTFP.

Solves the piracy problem at the user end...

[stagg]

If this goes mainstream we won't get in trouble for downloading "stolen" products, we'll get in trouble for stealing/cracking encryption keys. That should be even harder to police.

Already being done

See BBC iPlayer/Kontiki

Not only do they want to turn your own PC against you with their DRM, they also want to use your upstream bandwidth. All the disadvantages of torrents and all the disadvantages of legally bought "treats the buyer as a criminal" DRMified files rolled into one

Waste of bandwidth and disk

[mysidia]

If you only get the low quality anyways, why does it make any sense for you to be forced to pull the bits in the high quality version? This is a reduction in efficiency and convenience. Due to the long transfer times required for high-quality content, and very short transfer times required for smaller low-quality content.

There's a simpler solution to this: use keyed/passworded private torrents.

Make different quality versions different files.

Then the customers who purchase low-quality content don't get to download the same file as the ones who purchase high-quality content, and it means, less bandwidth and disk space is used.

If they change their mind and wish to buy a high quality version, they can simply download the high-quality version once given access. Upon successful download replace the lq file.

This technology is superfluous.. it shouldn't be patentable, because it's not an actual improvement.

Inventions have to be improvements to be patentable... it's called useful discovery

As required by the constitution: To promote the progress of science and useful arts...

Their technology does not offer an improvement versus pre-existing unpatented technologies in common use and simpler obvious ways of accomplishing the same thing, they do not have a useful invention.

Embrace, extend, extinguish

[HeckRuler]

FINALLY Microsoft reaches out to embrace, extend, and extinguish DRM.

Why are you guys so upset?

[pclminion]

I always have to laugh when people complain about patents on technologies they hate. Hello? They PATENTED it. That means nobody else is allowed to do it. And Microsoft of course, will fail at it themselves. Thus the effect of the patent is to PREVENT these sorts of DRM mechanisms from proliferating. Use your brains people.

Indeed

[DrYak]

Indeed, using DRM-protected torrent to distribute paid-for content was attempted by several players almost immediately by several provider when bittorrent appeared. And lots of less-legal sharing cites may encrypt the torrents so only members of the community could access its content.

In addition, having different levels of quality in different packets of the same stream (the more packet you have, the better the quality), has been proposed in lots of old systems such as the OGG/Vorbis compression (so that a web radio emits only 1 single stream and quality decreases as packet are dropped, instead of having to emit several stream of varying quality). In fact, progressive JPEGs work in a similar way (first chunks contain low-res blurry image, later chunks add the missing details), except that they are not a media stream but static pictures.

Meanwhile the patent was applied for only in 2005. The only thing that wasn't widely used before, is using separate key on each different "quality" packets. But it looks almost straight forward given the other technologies.
