In-Depth Information
DRM helps to prevent illegal downloads by requiring access verification
to protected material. To access DRM-protected material, the user needs
a username and password, which are stored in a database. DRM also
helps to prevent already downloaded files from being widely shared with
others. For example, iTunes downloads can be burned to an audio CD a
limited number of times, can be placed only on portable devices that are
registered to the signed-in user, and will not play if manually copied to
another computer.
Some software vendors use DRM to allow document authors to pro-
tect content created with the software. Access to a document may be
restricted by requiring anyone who opens the file to log into a DRM
server online.
Opponents of DRM
DRM is not without controversy. Indeed, many organizations and computer scientists are opposed to the practice.
Some argue that the use of DRM restricts users' access from using content they have rightfully purchased as they
see fit. For example, DRM prevents legitimate users from making personal copies of materials, lending copies to
friends, and so on. In addition, DRM may on occasion prevent legitimate users from accessing their content. Finally,
many argue that the use of DRM is pointless, as more often than not, users are able to crack the codes used to
secure content.
Software Licensing
When you install an operating system or software program, one of the
first stages of the process is to agree to its terms and conditions. These
terms and conditions are presented in a legal document called an
End
User License Agreement (EULA)
, the end user being you. The EULA
defines what you as a user can and cannot do with the product you are
about to install.
End User License Agreement (EULA)
A
legal document that grants you permission to use
a piece of software.
You will not be able to proceed to the next stage of the install until you
accept the agreement (see Figure 12.1). If you choose not to accept the
terms and conditions, you won't be permitted to install the software. It
may take a few minutes to read through the terms and conditions, but
it's a good idea to do so, so you will know what you can and cannot
legally do with the software.
For most vendors, licensing is a way of ensuring that they collect revenue for the products they offer.
Vendors also use licensing to ensure that if people use the software to break any laws, it is the user who
is in trouble, not the vendor.
