Moodle Extension for CopySafe Web Protection
Insert CopySafe Web Protection into Moodle from the page
This extension enables the use of CopySafe Web in Moodle pages,
resulting in web pages safe from all copy including Print Screen
and screen capture. By adding a CopySafe Web encrypted image to
any web page will add protection for all content on that page
including normal images, text and video. So even if a small 20 x
20 pixel CopySafe image is added, when it loads it activates the
CopySafe Web browser plugin to control copy methods and prevent
screenshots. CopySafe Web is supported in popular web browsers across all Windows computers
since XP (92% of net users).
- Copy protect images and all other web
- Safe from Print Screen and all screen
- Encrypted images cannot be retrieved
from browser cache.
- Domain locked images cannot be used
- Encrypted images stored on the server are safe
from your web host.
- Encrypted images cannot be saved or scraped.
Normally, adding the code to use CopySafe Web on a pages
as complex and sophisticated as Moodle course resources can be
frustrating even for the most experienced web developer, but by
using this Moodle extension, inserting CopySafe Web protection
is now as simple as a clicking a button and ticking the
checkboxes for the options that you want to employ. From the
Moodle course editor you can add CopySafe Web images from the
TinyMice HTML editor by clicking the [C] button in the editor's
tool bar. The shortcode (placeholder) will then be inserted at
the current cursor position. Image size and protection settings
can be set as you select the image to use or at any time later
by simply editing parameters the in the shortcode.
How the Moodle CopySafe Extension Works
When editing a page or post, click on the [C] icon above the HTML editor toolbar to insert the
"shortcode", where the cursor was last placed in the text area. After uploading or selecting an existing image (from a previous upload), you can then nominate the security settings to use for the page or post. Different pages can use different security settings, for example, to allow the submission of web forms you may need to enable use of the keyboard.
|| Width of the image in
|| height of the image in
|| Enable protection from
Print Screen and screen capture
|| Disable use of the keyboard
while the page is on display
|| Disable use of web browser
|| Prevent computers using
remote or virtual connection
| Border Frame
|| Add a border to the image
nominating frame thickness and
|| Add a clickable link to
the image and nominate target
Default Settings for this Moodle Extension
Default settings can be applied to all CopySafe Web pages and
posts. Most useful for corporate networks and others who need to
limit access to certain types of web browsers, the default
settings page allows you to nominate which ones you want to
allow. Any browsers not qualifying will be redirected. You can
also select from 3 modes which can be changed at any time:
| Demo Mode
|| Allows use of the
without requiring a CopySafe Web
|| For users licensed to
CopySafe Web software for
| Debug Mode
|| Displays the HTML for
object tag instead of displaying
* While the CopySafe Web Moodle Extension is designed for use by CopySafe Web software users, it will add a layer of protection for the page even in "demo" mode. For example, in demo mode, you still have protection from right-mouse-click, drag-and-drop and also control which web browsers can access the page.
CopySafe Web Licensing
CopySafe Web software enables the encryption of images that
invoke the CopySafe Web browser plugin when displayed to prevent Print
Screen and screen capture. When
such an image loads, it activates the plugin and when the user
closes the page, the potential to copy is restored. To fully enjoy the
protection of this solution, a domain license is required for the
software that creates the encrypted images for use on your website. Unlicensed images will not display. Nor will they invoke
the browser plugin to enable protection from Print Screen and
CopySafe Web Version Detection & Plugin Installation
When CopySafe Web is applied to a web page, a visitor gets redirected for download and install instructions if they do not have the browser plug-in installed. So as a visitor loads a CopySafe Web page, their web browser is checked for the plugin and verified if their version is current. This
Moodle Extension includes everything needed for this task, including download and error pages.
CopySafe Web Insert Method
The "CopySafe Web Insert" method refers to the ability to add a small 20 x 20 pixel image to invoke the power of the CopySafe Web plugin. Thus any media can be protected from Print Screen and screen capture. So to protect embedded PDF, Flash and video in your pages and posts, all you need to do is add that small CopySafe Web image.
for All Types Of Media
Note that CopySafe Web provides the most secure all-round protection for encrypted images but when that encrypted image is merely invoking protection from Print Screen and screen capture, there will be other ways that a visitor can save your media, if you let them. For example, a video or Flash movie can still be downloaded directly because the link to your resource can be found in the page's source code. In fact, most video grabbers locate media this way.
So to protect Flash and video from direct downloads and site grabbers, your media needs to either be encrypted and domain-locked like the CopySafe Web images, or they need to be "streamed", which is performed by linking your embedded media player to the media server, instead of linking directly to static files stored in a folder on your website. "Streaming" is more secure because it does not provide a media download, but instead delivers the video in packets. Another advantage of streaming is that media servers can usually detect the speed of a user's Internet connection and adjust download and bit rates for improved viewing experience.
the Level of Protection on Different Pages
Full protection can include limiting the use of task bar, menus and the keyboard. On some pages, you may want to use full protection while on other pages such as web forms and mouse interactive objects; you may want to ensure that the user has full use of mouse and keyboard keys. The default settings is full-protection, so you can enable the following options by simply changing their parameters in the page's setting file from true to false.
Download For Moodle CopySafe Web
Different packages are available for different Moodle
versions. The main difference between these is in the page
editor because every time Moodle upgrades, they use different
TinyMce resources and the insert control for adding CopySafe
Web starts from the page editor's toolbar.
Note: The packages and install instructions are very different
between Moodle version 2.2.4 and later versions because the
earlier version requires extra code for the tiny_mce editor.
Also, that only modules for version 2.5.1 and later can be used
with the CopySafe PDF module on the same web site.
The downloaded package can be uploaded
to your website using various means. If
you are uploading via FTP or a file manager
within your website's control panel you may need
to unzip the package first and then upload it
folder by folder.
The full install instructions can be found in each package in
both text and PDF format.

Until you have a CopySafe Web software license and real
encrypted images, or if you just want to use this Moodle
Extension in demo mode to add protection from right-mouse click
and drag-and-drop, you can use the encrypted image included with
the download or this
one. While this 20 x 20 pixel image may not be registered
for your website on the Internet, it will function on any test
server running at localhost. When prompted to upload or select
your first image, you use this one to get started.
- Enable or disable protection from Printscreen and screen capture
- Enable or disable the option viewing by computers using remote or virtual connections
- Enable or disable use of browser menus
- Enable or disable use of the keyboard
Managing Images Used With this Moodle Extension
Encrypted images cannot be rescaled, so the images that you
upload need to already be sized to suit your project. This means
that the original images need to be scaled before conversion by
the CopySafe Web software.
