![]() If you trust users not to use Adobe DRM removal tools, then you might equally trust them not to share your ebooks with others and therefore have no need to implement DRM protection to begin with. Type in ‘Adobe Digital Editions DRM’ in Google and all of the top ten results (apart from one for the Adobe site) are for instructions on how to easily remove it.If you type in ‘ePub DRM’ in Google – nearly all of the top 10 entries are dedicated to ePub DRM removal.What protection are your ebooks getting against piracy and theft if the security can be easily removed? It will not protect ebooks from piracy due to its insecure implementation and poor key management. If you are concerned about ebook piracy, then Adobe DRM for ePub and PDF formats is not suitable. The ePub format, however, lacks the cross-platform consistency of appearance (form and format) of the PDF and many subtler controls. However, just like your choice of browser (Chrome, IE, Firefox, Safari, etc.) they all display content slightly differently. Users can choose between many different ePub readers.It is much lighter than PDF, so it is better suited to smaller, less powerful devices.Note, however, that it cannot handle text in multiple columns and tables may not display properly on different screen sizes. You can create responsive ebooks that resize automatically depending on the device they are viewed on.It supports multimedia and interactive (ePub3) elements.The ePub format (XHTML) was developed specifically for internet publishing: Let’s compare this to a perpetual Locklizard Safeguard license:Ĭhoosing the format you publish in (ePub ebook or PDF file) is very important, and comes down to whether you are willing to trade multimedia and interactivity for security and consistent appearance across multiple devices. You will need to pay for Adobe Content server to apply the DRM protection, which will set you back $10,000 for the initial license, plus $1,500 in annual maintenance fees, a development and deployment cost of $5,000-$10,00, and a $0.20 fee per ebook download.Īll of this for protection that is not even effective. While the Adobe Digital Editions app is indeed free for consumers to download, the cost to publishers is significant. Is Adobe Digital Editions free?Īccording to Adobe’s official webpage, Adobe Digital Editions is “available as a free download”. ePub DRM has not proved to be effective, and whilst Adobe Digital Editions will continue to be used for its convenience, it may never provide effective ePub security or eBook DRM. But the implementation of ePub DRM or PDF DRM using Adobe Digital Editions has not had a similar level of success. The concept behind Adobe digital editions, to be able to publish eBooks in a ‘standard’ format (ePub eBook or PDF eBook) and have them reproduced faithfully on a wide number of different platforms, is very good. It is difficult, then, to obtain a secure ePub document, and ePub security continues to be problematic. However, many ePub DRM removal products remove even this protection because they crack the ePub file directly rather than relying on a specific version of an eReader. Adobe announced with Adobe Content Server 5 & Adobe Reader Mobile SDK 10 an improved and hardened DRM solution to protect PDF and ePub files from unauthorized viewing – this basically forces users to use an eReader built on RMSDK 10 and above. Adobe Content Server is used as the host management system, but available hacks of the Adobe ePub DRM system were widely available from the offset. So, it seems that the failure of the DRM technology itself has not completely turned the market against the format. These include Barnes & Noble, Kobo, and Sony.ĭuring its relatively short life so far (at least, as compared with physical books) Adobe Digital Editions has gathered a number of adherents, and copies in this format are still being sold at the time this article was published. ![]() It is far from perfect, however – with even Wikipedia listing methods to remove the ePub DRM security (Adept) from Adobe Digital editions and its derivative formats. Adobe DRM for ebooksĪdobe ePub is a popular format for displaying e-books and it can be readily converted into the Adobe PDF document format (ePub to PDF). Open formats like ePub are therefore not necessarily as “open” as stated, being contingent upon closed-source software to function at a commercial level. Though the ePub format was meant to be an open, vendor-free format, Adobe quickly became the main ePub DRM supplier. For Adobe, the compound term means, “part of the end-to-end Adobe ebook platform for authoring, protecting, and delivering ebooks across devices.”Īnd the focus here really is the ebooks, specifically the PDF and (more heavily), the ePub format. The term Digital Edition has been applied to almost any work (book, picture, music recording, film recording) prepared in a digitized form. ![]()
