Windows Tip Sheet
Can I Get a DRM with That?
Maintain exact control over user access to information through digital rights management, but be prepared to explain its complex licensing structure.
Something your users may be running into—soon, if not now—is Microsoft’s
digital rights management, or DRM. While DRM has been around in products like
Windows Media Player for some time, it’s finally starting to hit a critical
mass and finding more widespread use; with DRM also built into the latest version
Microsoft Office, you can really start taking advantage of it—or confuse
your users.
The whole point behind DRM is to allow information—whether it’s
a Word doc or a video—to be freely distributed but only viewed by someone
who obtains a license for it. Obtaining a license can be swift and silent in
the case of a license that’s free, or it may involve a payment process.
What’s confusing to many users is the fact that licenses are so flexible.
For example, all licenses can have a lifetime, which may be tied to a time
period or to a use counter. For example, a license might allow you to play a
video for a week, or just two times—a popular scheme for many movie-on-demand
services like MovieLink. A license can also control what you do with the licensed
information. For example, a DRM-protected audio file might allow local playback
on your computer, and it might give you the ability to burn the file to an audio
CD five times. It might prevent you, however, from copying the file to a portable
media device. It’s all up to whoever issues the license, so tip one for
your users is to investigate what a license allows them to do before paying
for it.
Licenses use a form of digital encryption to do their job, and they’re
keyed to unique aspects of the user’s computer, such as a unique copy
of Windows Media Player or Microsoft Office. That means licenses can’t
necessarily be carried between computers (although they can be backed up for
safekeeping). A movie file’s license, for example, might only ever work
on a single computer; if your user gets a new computer, they might also be required
to obtain a new license. Again, it’s all up to the license issuer, and
those are important details to check out in advance.

Have you seen a LightScribe-equipped
CD burner? LightScribe is an HP invention, and it uses a special
laser and CD to burn a visible, monochrome image into the top
of a CD, in much the same way a laser is used to burn data into
the bottom. LightScribe is a cool way to burn data CDs with
burned-in labels, eliminating sticky paper or plastic labels.
Units are available from HP
and other manufacturers. |
