Correct, however they can randomize certain words in your copy to watermark it and trace it back to you if it ever finds its way to the public internet.
- miki123211 5y agoRumor has it that Polish ebook publishers do exactly that. In Poland, there's no single E Ink reader company, so there's no DRM standard that would be compatible with all devices that you might want to read your books on. As a consequence, offering unprotected epub files is standard practice here, but all kinds of watermarks, from divs that are 1px by 1px, to subtle modifications of your book's cover, are pretty common. You can beat this kind of watermark pretty easily by getting three copies of the book and comparing them with diff. You need 3, not 2, so that you know which variant is the original when you notice a difference.
- no_time 5y agoInteresting. I knew you could defeat the protection with multiple copies but the number of copies needed to do it could be increased massively. Let's say they want to catch a serial leaker. They could do massive "watermark cohorts". Like several thousand units sold big. It would surely take several leaks to narrow down the suspect but combined with time information it would pose a significant risk to whoever wants to leak books. Also, >In Poland, there's no single E Ink reader company lol imagining a tech sector without a monopoly or an obviously harmful duopoly is wild.
