How To Copy Protect Web Pages & Online Images
Protecting the text on a web page is possible by using
encryption but once displayed in a web browser that text can be
saved or copied using nay one of the many methods enabled in
most web browsers.
Protecting media and images is even more difficult because that
media, whether it be an image or a movie file, will have a
unique link to it which is the means of locating it so that can
be displayed. Links to media can be protected by encryption and
cloaking but only until the page is displayed in a web
browser, after which it can usually be saved and or copied in
numerous ways afforded by modern browsers and computers.
Copy protecting web content displayed in a web browser
Once a web page has been downloaded to a visitor's web browser,
its content will be on full display and can be copied by using
various commands enabled in a web browser and to computers in
general, plus they can be copied by using screen capture
software. Consequently html encryption and image encryption can
no longer protect the content so a method of preventing copy by
Printscreen and screen capture is required.
Preventing copy by printscreen and screen capture
There is only one solution, and it's the only solution that
works in all web browsers while preventing copy from all screen
capture software. CopySafe
Web provides protection from all copy and can be used on any
web page by simply adding a few lines of html. When a visitor
first loads a CopySafe protected web page, if they don't already
have the plugin installed they are redirected for download with
instructions for proceeding. the CopySafe Web plugin is
supported in all Windows web browsers and has been in service
globally since 1999 providing copy protection for telecoms,
hospitals, governments, the military and many other industries
where copying can be critical.
Copy protecting online images
CopySafe Web was
originally specially designed to protect images displayed on web
pages. Not only does it provide the most effective protection
from copy but it also protects the images stored online that are
accessible by company staff and/or your web hosting service. The
CopySafe
Web software imports normal images and encrypts tem for
display on web pages. In fact it is the only solution that has
ever been able to display encrypted images on web pages. Those
encrypted images cannot be used anywhere else and can only be
displayed on the web site to which they belong because a domain
key gets embedded in the image.
The CopySafe
Web plugin is the only means of decrypting the
image and reading that key, so if it's found to be on an
unauthorised web site then the image does not get shown at all.
Another key factor to the security of images encrypted for
CopySafe is that while they can be located in a web browser's
cache, they are still in encrypted form and therefore useless to
any would be pirates.
Copy protecting all other web page media
The addition of even the smallest CopySafe
Web image to a web page
can apply copy protection to any web page because it is the
loading of that encrypted image that invokes the CopySafe
plugin. Consequently any web page anywhere can be copy protected
and any content including other images, Flash, PDF and video
will similarly be protected from printscreen and screen capture.
Of course care is needed to ensure that links to that content
are carefully obscured and that your protected pages are not
accessible to search engines or other spider/site grabbing
applications that follow hyperlinks.
Can such copy protection be more secure?
Yes. But only buy using another ArtistScope solution known as
the ArtistScope Site
Protection System (ASPS). But for most web site operators
ASPS may not be feasible as it requires a dedicated server or
least a virtual server or one where the operator has admin
rights to install software below the site root. ASPS uses a
special web browser specially designed to protect content rather
than expose it like all other web browser do. If your project
involves mission critical content such as exclusive corporate or
product information, or online lessons that would affect your
livelihood if they were to be redistributed, then you should be
using ASPS as there is no other solution that can provide
such absolute copy protection.
