WEB RESOURCES:

Disabling Right Click: Anyone can grab a Web image by right clicking and having it saved. The easiest way to stop this is to insert a ‘No Right Click’ command that disables the mouse function on your page.

Watermarking: Watermarks are copyright or other information added to an image. These can be either visible or invisible. A visible watermark is usually a copyright symbol or text that overlays the image. It makes copying purposeless, as ownership is clearly established. Invisible (or digital) watermarking embeds copyright information into the actual image file, while special software then helps you track down unauthorised copying.

Java Script Rollovers: Here, a copyright notice replaces the image when a mouse cursor passes over it.

Transparent Overlays: Overlay your image with a transparent GIF image. Only the top, worthless layer will get saved when a plagiarist right-clicks, thus protecting your work.

Slicing Images: Images can be ‘cut’ into pieces that are later spliced together in table cells. If someone wants to steal an image, then, they will have to save each piece and face the challenge of reassembling everything together.

Encryption: This is done with the help of special software, and can protect image as well as text files against unauthorised downloading and printing. The prices vary widely, as do the levels of security.

Finally, you must realise that no technology can be hundred per cent ‘cheat-proof’, so try a few of these simple steps as well: Copyright your work. Always keep your work files as they can be used as proof that you were the creator of an image. Place a copyright notice on each page of your site. If you discover your images on another site, contact the owner or Webmaster and explain that the images are being illegally used. If you are still not satisfied, seek professional legal advice.
