Forms and Systems to Protect Copyright
There are a number of ways to protect your works, however with
digital works now prevailing in the publishing of new works, forms
of protecting works is becoming more complicated - and more difficult!
Apart from the standard statement of copyright protection such as
: © Electrosmart Ltd [you may also add the words: "All
rights reserved." ]; there are various systems to help prevent
your work being copied, including:
A digital watermarking system embeds an image and/or copyright
information into the pixels of your work. Digital watermarks are
mainly used on graphic works, but can also be applied to text works.
The watermark is not visible to a viewer on screen in its original
location, however should the image be published on another site,
and the watermark with its copyright information will appear.
Many graphics software programs include a digital watermarking
system, such as Digimarc used in Adobe Photoshop, CorelDraw, and
The Digimarc System also provides a means to discover who may have copied your
image and where they have published it on the Web. This is done
using Digimarc's Web bot, MarcSpider, which scans the Web for your
images on other websites. In addition, MarcSpider's evidence provides
a very strong basis for taking a copyright infringement case.

Encryption is used mainly to protect the content of messages and
any data input into forms online. The most common form of encryption
uses a public key. It can be used on any digital file, text, or
Public key uses one key to encode a file [your public key] and
one key to decode it [ clients private key]. This means that the
data in the message cannot be decoded by anyone but the intended
recipient who holds the private key. Hence, using encryption only
works within a limited domain and is not suitable for work that
needs to be widely viewed. In cases of transactional nature, the
private [decryption] key resides in a secure computer, inaccessible
Macromedia's popular Flash software converts graphics and text
into a special format that is viewable by a standard web browser,
unless the owner has turned off flash.
Flash files prevent reuse of parts or printing of the content.
However it does not protect the content in total - where an infringer
may download the entire Flash file and show it on their website.
There are also ways to easily screen dump static images from within
the Flash presentation.
Hence, Flash is not particularly secure from copyright infringement.
Adobe Acrobat PDF
Acrobat PDF files that use a password to open them can prevent
content from being printed or graphics from being copied directly
[although there are easy ways around this for computer savvy people].
Acrobat also includes an optional eBook format that prevents files
from being opened by any person other than the person who bought
them. There is certain reluctance by purchasers to the use of secure
ebook formats that require software for viewing.
Adding certain HTML coding can help you protect your copyright by preventing
copying or viewing of source code. These scripts are available either
free or at a very low cost for the comfort of keeping your content
in your control.
The above systems only protect work from the general public who
have no knowledge of how to circumvent the protection. Typically,
there are now software products designed specifically for this purpose.
Many of these developers are legitimate companies, and not just
Overall, any technology designed to provide copyright protection
is likely to attract software to undo the protective layer.
