SECURE DIGITAL BOOKS
What are secure digital books?
Secure digital books are, of course, digital books (or ebooks, if you prefer) that have had some security applied to them. Being in a digital format they may contain different forms of information from traditional paper based books. The print medium is static – fixed text and images. The digital book may use multimedia in the proper sense – text, pictures, sound, moving pictures, video/film in order to provide its results.
So making secure digital books is not quite so simple. Because a digital book is able to extend the capability of the traditional book into other dimensions, so the underlying technology required to replay the different sections of the book may require different types of security mechanisms if it is to be effective.
This means that the use of multimedia in a digital book requires more security methods and techniques if it is to be a secure digital book. And this may introduce a certain amount of complexity into the different ways in which secure digital books can be provided.
Some book formats, such as Adobe PDF, allow you to use one method for a secure digital book, because you are only dealing with one type of format of presentation.
But if your digital book uses multiple formats, such as the multiplicity of video formats (mpg, mpeg, wmv, avi, mov, 3gp, mp4 and so on) it may prove difficult to find a simple way of getting you secure digital book, especially when there are so many possible players that might be used (automatically, if the operating system is able to be preset to run what it wants to).
One approach to resolving how to obtain a secure digital book is to limit the actual number of presentation formats that you wish to support. This is not likely to be a simple matter, especially if you are using existing work that has been created following a particular standard. One current answer would be to convert whatever format has been used to produce the original material into a single common format. Although not a specific recommendation the Apple Quicktime system appears currently to be a common format for both the Mac and Windows platforms, since it appears to be embedded into both operating systems and is essentially ‘free’ to the users of those systems.
However, most companies are now migrating their audio and video formats to flash. There are numerous programs available that will convert most audio and video formats to flash. Over 97% of all browsers have the free flash player installed, so you won't have to worry about your audience not being able to view your flash files. Flash files will also stream through firewalls and do not require a streaming server so you can put flash files on your website without the need for any extra hardware.
But even if you have converted all your audio and video works to a single format, you need to be confident that the other static formats – text, pictures and so on, can be secured. That means choosing a method of presentation that can support multiple formats apart from flash, probably including html and common picture formats such as JPG and TIFF. So to provide secure digital books requires a system that can handle many formats, and provide security against copying and printing where materials are multimedia, pictures and text.
