Either way, I am not surprised that they are out there. It would be nice if they get themselves caught. I doubt that is going to happen but who knows.
Not that it matters, there were professional copies available before the e-books were sold any way. |

It's easy enough to strip text files (html, css, opf, ncx, xml, xpgt). The questionable part are the graphics. It's possible those may have watermarks that can survive conversion.

I was looking at my copy of the first book last night and it has two copies of the file for the Hogwarts crest, but they are slightly different sizes although visibly identical.
Now I know that the book includes the first chapter of the second - and includes the cover, title page etc from that book - including the page with the crest, but wouldn't it be more normal to link back to the same image file? (or can't you do that in ePub?) Even if you need two separate copies you'd think they'd be the same size. Can't help wondering if there's some watermarking in there. |

I purchased the HP books and have been looking into the watermarking for my own curiosity and not for any nefarious purposes.
I won't provide any specifics, but I can tell you that watermarking does exist in (at least) the following locations: Copyright page, CSS file, JPEG EXIF data, PNG steganography, and in the filenames/links themselves. It's quite secure, much more so than I originally thought, and some of the approaches were clever enough to bring a smile to my face. As I had never peeked into an eBook before, I'm especially pleased with what I've been able to learn about the ePub format as a result. |

Also Rowling shouldn't be concerned, the HP books were already available, this way she's getting money off of all those of us who wanted the option to get the books legally. |

Actually, I read in the Financial Times that Rowling was originally reluctant to release the books in digital format, fearing...correctly...they would be pirated. Which is why all purchases have to go through her Pottermore site, ensuring control via watermarking...and higher profits. The rich just keep getting richer...as they say. |

We could post the MD5 hashes of the images and see if they differ at least. I've got the UK version of Prisoner of Azkaban from an Overdrive library last night (which might or might not be representative of books purchased through Pottermore - I suspect it isn't), and it has these images with these MD5 hashes: MD5 (OEBPS/images/cover.jpg) = 44191b6547e4563c7f4facf047752fe8 MD5 (OEBPS/images/cover4.jpg) = 012e75183308ec8a1bb83de61faf5147 MD5 (OEBPS/images/logo.jpg) = cb7dd835bcefc545840e5e20dd1a7dfc MD5 (OEBPS/images/title_image.jpg) = 9855cd4600f24373c342ca9811ad523c MD5 (OEBPS/images/title_image4.jpg) = 9855cd4600f24373c342ca9811ad523c Cheers, Simon. |

I'm not saying that's what happened nor that there aren't easier/more likely ways, but that wasn't the original point I was trying to make with my post. It was that someone doesn't have to even attempt to remove watermarks and be certain they've got them all before uploading to a file sharing site if the watermark doesn't identify them in the first place. PS it was a good pun Quote:
Putting everything through the pottermore site will not make a single bit of difference about whether it's pirated or not, neither will the use of watermarks. It could be totally DRM free, watermarked or adobe/amazon infested, it would be pirated all the same. Of all the reasons for not releasing ebooks, piracy imho is the most silly one for her to consider. Last edited by JoeD; 03-30-2012 at 08:15 PM. |

I worked it out by closely examining the images based on an earlier post in this thread. I'm sure I looked something like this: Last edited by seanbob; 03-31-2012 at 05:24 AM. |
