New Updates for eBook Solution
Today, Adobe has released an update to our Digital Publishing Solution for eBooks, including Content Server 4.1 and Reader Mobile 9.2 SDK. With these updates, book distributors can enable “social” password-based content protection as well as text-to-speech accessibility support for eBooks. In addition, Reader Mobile SDK includes a number of rendering, font, and color management enhancements.
Social, password-based content protection
The release of Content Server 4.1 enables “social” password protection for PDF and EPUB eBooks. Like before, Content Server operators can protect PDF and EPUB files using identity-based authorization. Under this identity method, eBook files are authorized to a specific user who authenticates using his/her Adobe ID and password. With the release of Content Server 4.1, publishers and content distributors now have the additional option to protect eBooks using “password-only” authorization. Under password-only authorization, eBooks are not associated with an Adobe ID; readers only need to enter a password to access the protected content.
This new option enables a new level of flexible “social” permissions for publishers and book distributors. With this option, readers only need to enter a password to access content and are enabled to share their eBooks with those with whom they entrust their password. Because Content Server 4 operators determine the password requirements, some operators may choose to make the password something users are unlikely to share (retail account password, credit card number, etc.). This is not a requirement, however, and other operators will choose to enable passwords that facilitate sharing. For security, any password users enter to authorize content is converted to a non-reversible one-way hash of the string.
Devices and applications that use Reader Mobile 9.2 SDK will support files protected by this new password-only authorization.
Text-to-speech accessibility support
Content Server 4.1 also includes support for text-to-speech as part of the available content protection permission set. With TTS permissions enabled, print-disabled users can access content through “read out loud” functionality on devices using the Reader Mobile 9.1 SDK. As part of our commitment to deliver accessible eBooks for all users, the default TTS permission in Content Server 4.1 is set to “enabled”. Because some publishers may choose to disable TTS, Content Server provides flexibility so these publishers can determine their own policies in distributing titles. However, we strongly encourage publishers to keep the default “enabled” TTS permission in protected content to maintain eBook accessibility. This approach enables publishers to strike the appropriate balance in controlling how copyrighted works are distributed and ensuring eBook accessibility.
With Content Server 4.1 and Reader Mobile 9.2 SDK, operators can now choose the level of sharing they wish to enable among end-users and provide accessible eBooks to print-disabled users. Current Content Server 4 and Reader Mobile SDK customers can obtain these updates at no charge.
