Aaron Swartz Ebook's DRM Has Been Cracked (hackaday.com)
Slashdot reader jenningsthecat writes: From Hackaday comes news that the collected writings of Aaron Swartz, released as a watermarked eBook by publishing company Verso Books, has had its watermarking scheme cracked by The Institute for Biblio-Immunology, who also published a guide for removing the BooXtream watermarks.
The writings of Aaron Swartz, with DRM applied? Oh, the irony. Still, at least the DRM employed doesn't restrict a user from reading the book on any and all capable devices, so it's not a very intrusive form of DRM. But I somehow doubt that Mr. Swartz would take any comfort from that...

Yes, the files should have been pubicly available, but it doesn't mean he gets to break into server rooms to get that content.
if the guy who cracked the e-book gets railroaded to a 50 year sentence and $1 million in fines then kills himself, only to have his writings published in a encrypted e-book, which in turn is ...
If you've been wanting to read Aaron Swartz's writing but were philosophically opposed to the company's DRM, this is good news for you I guess.
I always like hearing that another one of these silly DRM schemes has been cracked... but, practically speaking, it's unlikely that "Verso Books" has any content I care about.

Watermarking is not DRM, and if you invent a term "Social DRM" to describe it and its consequences purely for the sake of controversy then it's still not DRM, because DRM and "Social DRM" are still two completely different things.
That said, DRM can be used as a mechanism for watermarking, and watermarking is itself anti-consumer (because the mere existence of a watermark corresponding to you is a liability, even if you never infringe on copyright)
This watermarking is different in that it is unique to every copy of the ebook. Maybe the text was locked inside a binary?

"This watermarking is different in that it is unique to each copy..."
It's not different. That's the definition of watermarking. If the watermark text was not unique, is would just be called "text".
It's easy to break this kind of watermarking. You get K copies of the book, compare them, and take the most common version for each element. Choose K based on your budget and the degree of confidence you want that you've scrubbed everything.
For bonus points, you can analyze the types of differences and create novel watermark elements to confuse the watermark reader even more.
You have to analyze several types of media -- like CSS, HTML, and images -- but it's still pretty straightforward.
So this isn't that interesting.
Watermarking isn't anything like DRM. It doesn't limit access to the work; assuming it's an otherwise standard format, you can still play/read it with anything that you want.
The fun thing would have been if they had use DRM. I suppose Swartz's estate (who?) is the copyright holder. DMCA defines circumvention as being a function of whether or not the copyright holder (not some other party) authorizes you to access the content. Presumably, Swartz' estate would authorize buyers to read the book. Therefore, you'd be legally allowed to crack whatever DRM were present, make/market/sell tools for doing that, etc. All legal because none of it would be primarily intended to circumvent.
As copyright owner of this comment, I authorize everyone to defeat any technological measure which limits access to it.
I applaud the usage of watermarks to enable catching copyright infringers without harmingmlegitimate uses of the material.
Watermarking favors piracy. If you get a copy of a watermarked file from a pirate site you have very little to worry about, since it's not your ID in the watermark. Someone would have to inspect the file on your PC to determine that it wasn't authorized. On the other hand, if you buy a copy of the file from the publisher using your own ID and your computer later gets infected, or a guest makes a copy, or installs a file-sharing program, or the file otherwise ends up on the Internet without your knowledge, you're going to take the blame for every download since all those copies have your ID embedded in them. As with the other, more intrusive, forms of DRM, the pirates offer a better product, this time in the form of anonymity.
