Security quote of the week
DRM is supposed to prevent piracy and illegal file sharing. In order to
provide DRM, you need at least $10,000 up front to cover software, server,
and administration fees, plus ongoing expenses associated with the
software. In other words, much bigger operating expenses than a small
business can afford. By requiring retailers to encrypt e-books with DRM,
big publishers are essentially banning indie retailers from the online
marketplace.
-- Ruth CurryDRM is like the anti-theft sensors by the doors at the drugstore. The sensors go off all the time, but they still can’t stop a crafty teenager who knows how to remove a magnetic tag — nor can they stop criminals who break in and steal directly from the till. Similarly, DRM prevents a lot of legitimate, noncriminal usage while remaining unable to stop actual, intentional piracy, or its crafty teenage equivalent: someone with internet access and the ability to type “remove DRM” into Google.

Actually, DRM is not supposed to prevent piracy and illegal file sharing. That's just the window dressing. It's supposed to control the players (or e-readers) market.

> DRM is like the anti-theft sensors by the doors at the drugstore.
Well no it's not. The drugstore only label's it's own property with the anti-theft devices.
With DRM you have your copy of some media that you paid for, on your device, in your device's memory, unencrypted, and the government says that it's a criminal act to not only have the ability to access the content's of your devices memory, but discuss it with others and share how your own device works.

It's hard to say that in a soundbite-sized analogy that will offend the layman.
DRM on an ebook is like owning a book but being required to call an 800 number each time you open it and if the guy on the phone says "No" for any reason, or just doesn't answer, then it's a crime to read it.
Still too wordy.

Analogies are used way too much to try to explain things and it obscures the issue.
The easiest way to describe the situation in laymen terms that I can figure out is:
The government is actively conspiring with international corporate conglomerates to strip away your private property rights for the specific purpose protect those corporations' profits against the combined threat of competition and individual freedom. This raises the cost of your product, creates new laws for you to get arrested for, and retards progress.
All for the sake of making people like Sony slightly richer in exchange for political favors, campaign contributions, and influence over the news reported by the agencies owned by said corporations.
This isn't about protecting against piracy, it's about greed and control.

People who value freedom and decentralization of power—my kind of people—have been singing this tune for more than a decade now. They keep saying that DRM can't work, that it is a boondoggle and a mistake on the parts of people who build it and deploy it.
This idea is very satisfying to those of us who believe that DRM is deleterious to society.
Trouble is, it's completely wrong. An unbiased analysis of the history of DRM will show that in the last five years it became a raging success. Most of the most profitable products of the current era, e.g. iTunes, all of the gaming consoles, iPhone, Android, etc. etc., are built on it. And this vast flow of profit comes directly from people—the vast majority of people—who don't have the time, skills, or willingness to take risks to try work-arounds. Those people suffer the negative consequences of DRM, such as inability to bequeath their digital possessions to their children, and they pay a higher price because of the resulting monopolies.
During this last decade, while freedom lovers have been confidently telling each other that DRM is hopeless, the proportion of the population whose daily life is confined by DRM has grown to 99% (in the "Developed" countries). Maybe if we spend another decade congratulating each other the proportion will have grown to 99.99%.
How about instead we face up to how we've failed to achieve our declared goals and start thinking hard about how to do better.

Security quote of the week Posted Apr 17, 2012 2:02 UTC (Tue) by jzbiciak (✭ supporter ✭, #5246) [Link] Watermarking is a form of DRM. It's just not intrusive DRM. Sure, the software doesn't actively prevent you from using the files in the way you're legally allowed to. But, the watermark provides a forensic tool to allow identifying you if the rights holders feel you've violated their IP rights. I guess it's the difference between active management and passive management. The former locks up the file until you prove you're worthy. The later allows access, but also leaves breadcrumbs to catch cheaters.

It depends on how you define DRM, it's almost always presented as a technical way to prevent people from doing the 'wrong thing', as such watermarking (which doesn't prevent people from doing anything) doesn't qualify.
personally, I'm just fine with watermarking, and I think that publishers should have a way to identify when a copy of something is being widely distributed. I think take-down notices based on watermarking make lots of sense.
The only problem with watermarking is the privacy angle, it can make it possible to identify what you read, listen to, and watch. As long as there is enough competition so that these records do not get centralized, and as long as you can create new online identities at will, I think that this will balance out in the long run.

I'm not sure I see this as such a small problem.
Records of how people choose to read etc don't need to be directly centralised to be a problem; far better just to share them for marketing purposes, as happens extensively in various areas at the moment. Which results in a significant privacy intrusion. I don't see how the ability to create new online identities at will makes a significant difference, as other metrics (especially payment) can presumably be used to link them, which is a very valuable thing to do for marketers.
Also, to my limited knowledge, removing watermarks, and even determining their existence, is very difficult. At least with conventional DRM you can be reasonably confident when to be wary of it.

How do you share watermarks?
If you upload your files somewhere public for others to download - you commit a copyright violation which should be traced back to you. If you place files somewhere private then who's going to be tracing them back to you?
That leaves out the questions of fair use (i.e. using a mix of clips in a Youtube video).
Security quote of the week Posted Apr 17, 2012 18:58 UTC (Tue) by dlang (✭ supporter ✭, #313) [Link]
If companies are sharing marketing information they won't care about the watermarks, they will just share the information about what you purchased from them directly.
Watermarks aren't very good if you can easily remove them (and determining their existence is the first step in removing them as it gives you a test to tell you when you have succeeded)
But the only way that watermarks affect privacy is if someone is going through the files on your system to see what you have and how you got it. If you don't share or sell your digital files, the only information available is the basically the same as finding the files there in the first place.

You're right (as is Cyberax), for some reason I was thinking quite muddily in my last comment. And this is a significant limitation.
I do still think that it's an issue, though. As Cyberax mentions above, "fair use" and similar sharing of watermarked files can reveal more than is reasonable; imagine an activist using a clip of a film to produce a video, which can then be traced back to their purchase (which is likely to be linked to their legal identity). Again the whole affair is more sinister if the watermark is invisible.

it's not that hard to get pre-paid credit cards and free e-mail addresses if you are worried about it. Today most people have a single online identity, but there's no reason that they couldn't have multiple ones (see the book "Earthweb" for examples of how it could be done)
No, watermarking doesn't give you complete freedom to do whatever you want with the contents with no ability to track back to some identity, but it does give you the ability to do whatever you want with the contents.
I think the main gain of watermarks is not that they will cause any enforcement lawsuits, but rather that if people know they are there, they won't do blatantly illegal things with the files.
Watermarking must be hidden to be effective, if you can see where it is, then all you have to do is change those bits and it's not watermarked any more. Watermarking is a use of Steganography (http://en.wikipedia.org/wiki/Steganography) and if properly done, nobody other than the organization that watermarked the piece can tell that it's been done. In fact, the same file could be watermarked by several different people without any of them being able to tell that the others had done so.
Everything is a compromise, and I see Watermarking as being a good compromise between protecting the copyright owner and restricting the purchaser of the file. They both have concerns, but neither's concerns are strong enough to completely trump the other's

> Watermarking is a use of Steganography and if properly done, nobody other than the organization that watermarked the piece can tell that it's been done.
Aside, of course, from the fact that files which decode to the "same" book/audio/video are riddled with inexplicable differences.
A source watermark can remain hidden, because you have nothing to compare it to; only a single watermarked version is released to the public. Steganography is similar; it only works if the hidden data is embedded in the _only_ available version of the camouflage material, and even then it can be vulnerable to statistical analysis. To use a watermark to identify the buyer, however, every buyer has to receive a different version. The fact that the file has been watermarked is thus perfectly obvious once you start comparing the files. You may not be able to eliminate the watermark just by merging multiple versions of the file (the result may contain several valid marks, rather than none), but you can at least identify the locations of the differences.
Moreover, any watermark which doesn't noticeably degrade the quality of the files can be eliminated through compression. Simply put, if you remove all the redundant data, there will be no room left for an invisible watermark to hide in.

Long time ago (as a joke), I developed a simple exe-program which fills-in a simple 'questionnaire' and sends it by e-mail (through FIDO).
Only this questionnaire also contained encoded passwords for Internet dialup. I used spacing between words to encode bits - one space was '0' and two spaces were '1'.
One can also simply replace words with synonyms at certain points in the text to encode the buyer ID, for example. It'll be easy to find, though.
For music you can use the least significant bits of the signal (in FLAC) or small frequency shifts (survives MP3).
>Moreover, any watermark which doesn't noticeably degrade the quality of the files can be eliminated through compression.
Not really. It's easy to create a watermark that survives more encoding roundtrips than you'd care to use without noticeable degradation of quality.

The easiest way to defeat these watermarks would be to buy several copies from different accounts and then compare them.

These are all trivial schemes which are easily identified and removed or randomized, given a few versions of the file with different watermarks for comparison. The "replace words with synonyms" scheme has the additional disadvantage of mangling the text presented to the reader, with isn't going to make readers _or_ authors very happy.

That's only possible because the compression isn't anywhere close to optimal. Optimal compression would only spend as many bits as are required to represent the data to the viewer/listener. Changing any of those bits would result in a noticeable difference, by definition.

In reality viewer/listener is human which evaporates your argument in hurry. I know this because I've actually participated in sound compression studies (it was many years ago, but the most important result stays). You actually can remove about 97-98% of the data from sound record and human will not notice anything at all! The catch? These 97-98% of data will depend not only on human, it depends on the state of said human. Tomorrow (when humidity or pressure will be different) you'll need another 2-3% of the data to hear it as “perfect recording”. This means that any sound record with “good enough” quality contains enormous amount of redundancy.

You're proving my point. If that "redundancy" can actually influence how a human would hear the sound, it isn't available for watermarking. The watermark isn't designed for a specific human in a specific state; it has to be transparent to nearly all humans, in nearly all states.
The bits used to transparently watermark an audio file cannot have a noticeable influence on the sound, by definition. Ergo, if they are not removed during compression, the compression is suboptimal.

BULLLSHIT! It has to be nearly transparent to nearly all humans, in nearly all states. See the difference? Because watermark is spread over tiny amount of data you can actually hear AND over much larger amount of data you can not hear it can not be removed with a simple compress/decompress cycle (or dozen such cycles). To make it initially completely undetectable you can just add it after compression. The bits used to transparently watermark an audio file cannot have a noticeable influence on the sound, by definition. Of course they can! The trick is to make sure they are not heard before compression/decompression cycle. After compression cycle you have differences anyway and you can only find out what distortions are result of watermark and what distortions are result of the compression if you have an original without distortions. The bits used to transparently watermark an audio file cannot have a noticeable influence on the sound, by definition. Sure, but “noticeable influence” != “any influence”. Ergo, if they are not removed during compression, the compression is suboptimal. Right. And compression is always suboptimal - see above. P.S. I think you don't get the full implications of the fact that we are talking about lossy compression here, not about lossless one. Lossless one is not interesting because it'll keep all the watermarks intact by definition.

Or if you have two or more versions with different watermarks, which, if the watermark is intended to identify the buyer, will be plentiful.
> I think you don't get the full implications of the fact that we are talking about lossy compression here, not about lossless one.
Wrong. Obviously only lossy compression would remove a watermark--lossy compression which encodes the original, pre-watermark sound in just enough bits to ensure the decoded version will be perceived the same way. Change any of those bits and not just the sound, but the _perception_ of the sound must change, for at least some listeners.
> And compression is always suboptimal - see above.
I'm not postulating the existence of perfect compression, but the better the compression, the less room there is for a watermark without compromising the fidelity of the original sound.
Of course, why go to all that effort when you can just make the watermark meaningless? Pay with an anonymous gift card, via a throwaway account, from a public or otherwise borrowed computer, and it won't matter how strongly they try to watermark the file--they don't have the necessary information to connect that watermark with an individual.

I don't think that's really true. My understanding is that the watermark is imperceptible so one could listen to many different copies of the same audio with different watermarks and not be able to tell the difference between them. I would also guess that a file can be re-encoded many times before the additional audio artifacts become perceptible and that a watermark could survive many re-encoding trips before being successfully obliterated. At that point the quality of the audio itself has probably also been obliterated. The people designing watermarks are also likely aware of how the data is encoded and decoded and so can design features that are most likely to survive many round trips. This reminds me of 56k modems which depended on knowledge of how the analog sound data was encoded to PCM digital at the CO.

Yes, that is how watermarks are supposed to work. For this to work in practice there have to be bits in the compressed version which can be changed to store the watermark without affecting the quality of the decoded audio. Of course, if we know which bits don't affect the quality of the audio, a better codec would just leave those bits out entirely.
> The people designing watermarks are also likely aware of how the data is encoded and decoded and so can design features that are most likely to survive many round trips.
Yes, watermarks are generally designed with specific codecs in mind. They depend on the coded retaining more data this is really necessary about the source audio, data which won't affect the perception of the audio and thus can be modified to store the watermark.
To eliminate the potential for a watermark you would need a better codec, one which more accurately models the listener's perception of the sound. The better the codec, the fewer bits are used to represent the sound at the same quality, and the harder it is to watermark the file.

Of course, if we know which bits don't affect the quality of the audio, a better codec would just leave those bits out entirely. Situation is quite asymmetric: if someone will notice and complain that watermarked sound is distorted it's easy to recall the watermarked file and replace it with differently watermarked file. If codec will produce distorted sound then you'll face a lot of quite angry guys. Thus pure compression will never be able to remove watermarks. Now, schemes specifically designed to remove watermarks are, of course, possible, but since noone will say to you if watermark is detectable in processed file or not (till you'll be sued, that is) it's quite hard to develop them.

Ah, finally got your idea. Ok, if you'll invent some compression scheme which compresses sound just enough to make sure not a single human can distinguish it from the original in minimum possible set of bits then it can be used to strip the watermark. This is great plan. The only problem: it's impossible to implement it if you don't have a detailed information about all future listeners and about all states of all these future listeners. You can as well invent something more realistic. perpetual motion machine (2nd kind if you know what I'm talking about), for example. Any realistic compression scheme leaves tons of information which can be perceived by some theoretically possible human, but is not perceived by any real human on real planet Earth (because there are insane number of possible combinations of receptors and less then seven billions of human beings). This is where you theory falls apart. I was under impression that we are talking about real music, real watermarks and real compression. If you want to discuss how many angels you'll need to remove the watermarks then it's separate issue - and I'm not sure I want to participate in such theological discussions.

The watermark scheme is under the same constraints. Sure, for any given listener and state there is quite a bit of redundant information left over. However, that information is needed for other listeners and other states, so it can't be used for watermarking.
A perfect compression scheme would make watermarking impossible. However, short of that, a _good_ compression scheme will still make watermarking _very difficult_. Moreover, knowing how to make a watermark which survives compression immediately tells us how to make a better compression codec which would remove the watermark. After all, any bits which can be changed to watermark the file without diminishing quality can just as easily be removed during compression without diminishing quality.

In theory, but not in practice. In practice you can only have sample of some files with watermerks, you don't have a machine which applies these watermarks. Thus now we are very-very firmly in “how many angels can dance on the head of a pin” territory. Watermarks add negligible overhead thus practical advantage in using this information for compression purposes is minuscule. We are talking not about compression at this point but about “watermarking removal” procedure. And like with real watermarks and real banknotes it becomes cat and mouse game. As history shows this game can only be won for a short periods of time: sure you may counterfeit old banknotes (and you'll probably be able to remove old watermarks from sound records), but people on the other side will introduce newer and newer schemes.
DRM success Posted Apr 12, 2012 20:37 UTC (Thu) by man_ls (subscriber, #15091) [Link] It is neither here nor there, I think. DRM only provides a temporary sense of security to old-style copyright holders who want some kind of assurance that their works are not going to be shared freely by people, even blatantly false. Also, DRM makes no business sense at all for these copyright holders in the long run. For example, publishers are cutting their own throat and giving Amazon all the power by using DRM. Apple has eschewed it for good in iTunes music.Even when DRM is in full force, most people will find out how to evade it, most of the time. Or at least they will probably have the option to use some kind of darknet, even if they are too scared to use it. And DRM is actually very deleterious to society.
DRM success Posted Apr 13, 2012 22:53 UTC (Fri) by rahvin (subscriber, #16953) [Link]
DRM has never been about security. DRM is about eliminating the used product marketplace. They know they can't do anything about sharing and blatant copyright violation. The Used goods marketplace has been something they wanted to get rid of for several hundred years, such as when early publishers printed prohibitions on resale above the copyright notice.
Government at the time was sensible and told the publishers they could print whatever they wanted but the right to first sale existed and the little statement with the copyright didn't mean diddly. Since that ruling copyright based companies have been trying to undo first sale. DRM gives them the right to make these products services rather than products and frankly it's an end run around sensibility and consumer rights like you've never seen.
Want evidence? There was a used digital music marketplace (name escapes me) that sprang up recently, they had a pretty darn secure way to make sure the music sold was traceable and tied to an account (I think they watermarked the tracks). The RIAA companies pounced, not because they think someone is going to commit mass piracy and sell thousands of the same song, the pounced because this was an attempt to bring back the used market they've worked very hard to try to get rid of.
Make no mistake, DRM has always been about eliminating resale and making purchased products a service rather than an owned product. Ultimately DRM has always been about gaining that specific control, piracy and digital copyright infringement are just the sauce to sell this massive breach of consumer rights. Not that they really need it mind you, when Chris Dodd can get on national TV and say he can't understand why the law he purchased didn't get passed and the vast majority of people don't even blink you have a corrupt system.
