What is DRM? How and Why Digital Rights Management Works

With a Digital Rights Management (DRM) system the PDF publication to be "controlled" is protected using either device-specific information and/or an authorization process. In the case of a device (e.g. a proprietary ebook reader like a Kindle, or a pre-registered device like an iPAD) the file is enabled based on the deviceID information, transmitted automatically to the DRM of the device service provider (e.g. Amazon). For generic devices - PCs, Mac computers, iPADs/iPhones (not using iBooks) and Android tablets and phones, entry of an authorization code is typically required, although this can be addressed via a prior user and device registration process. JavelinPro is a version of our Windows-based software which incorporates optional device/user registration thereby enabling offline authorization via a simple but highly effective document licensing process.

The process of checking the authorization code or license file is the key to DRM operation and document security. A valid deviceID or code is required in order to view the PDF. Once a valid code has been used it is effectively disabled for subsequent use on the DRM server, so sending the secured file and the code to someone else will not enable them to access the file. Likewise, a device-specific license file offers similar protection. This is entirely different to simply applying security to a standard PDF files, since that (may) protect the file content but does not prevent it being passed on to others or provide date/time protection. The Drumlin Security DRM service and the Javelin secure PDF readers go hand-in-hand to provide this authorization process and the PDF viewing facilities, with security controls, that deliver true copyright protection. This enables one to deliver PDF ebooks and other documents to Android, iPAD/iPhone, PC and Mac devices with confidence and ease.

More about Portable Document Format (PDF) files

PDF vs ePUB? - we are often asked whether publishers should opt for PDF or ePUB. The quick answer is that they are not mutually exclusive. If your source material is relatively uncomplicated in terms of formatting - graphics, table, fonts etc., then ePUB is definitely an option. The core difference between ePUB and PDF is that ePUB documents are re-flowable, so the format is not fixed and the page layout changes according to the screen size and font size selected by the user. The range of fonts available is generally smaller than with PDF documents. PDFs are page-centric and fixed layout i.e. fixed-format, not re-flowable and the font type and size cannot be amended by the end user. The second consideration is the distribution channel for a document. All the main eBook channels (e.g. Kindle, Nook, Kobo etc) are ePUB format based - they do not support DRM-protected PDFs. Drumlin and Javelin are designed to provide solutions for publishers whose preferred form of output is PDF - i.e. with the correct layout, fonts, pagination etc for their documents - as such, our solutions can be used on their own, or in conjunction with other channels of distribution such as ePUB services and print media.
