Anti Piracy Technique - Watermarking Images

Your reviewer found two interesting vendors who started to get tough on leaks. I will discuss about this interesting new feature added by one of these vendors.

This vendor sells skinning and special effects libraries in Delphi. This vendor uses CCR Exif library to embed a small change into the PNG and JPG files that makes up the skins and special effects library.

What happened the next few days? Vendor releases new version of his skinning library, pirate took the bait and the vendor recovered his library package (on certain file sharing websites), opened some of the images and on next release, your reviewer noticed people were begging for the latest version.

It sure beats clicking on those Rick Roll links. Thanks goes towards Mr. Christopher R. for his excellent library.
