Adobe Digital Editions
The software requires version 9.0 of Adobe Flash Player. The software locks content to up to 6 machines and allows the user to view the content on each of them. In March 2009, the author of the reverse engineering blog i♥cabbages claimed that he had broken the scheme. .Adobe Digital Editions is ebook reader software from Adobe Systems built using Adobe Flash. Adobe originally announced a Linux version would be published at the end of 2007 but later changed their mind.
It implements a proprietary scheme of Digital Rights Management, which since version 1.5 (May 2008) allows document sharing between multiple computers and user authentication through Adobe ID. Windows and OS X versions of Adobe Digital Editions were released on June 19, 2007. The software supports PDF, XHTML (through the nonproprietary .epub file type specification), and Flash-based content.
All promises of future versions have now been removed from the Adobe s official FAQ. Adobe Digital Editions uses the proprietary ADEPT (Adobe Digital Editions Protection Technology) digital rights management scheme, which is also implemented on some e-book readers such as the Sony Reader. It is used for acquiring, managing and reading eBooks, digital newspapers, and other digital publications.
