What is libgd-securityimage-perl
libgd-securityimage-perl is:
The (so called) “Security Images†are so popular. Most internet
software use these in their registration screens to block robot programs
(which may register tons of fake member accounts). Security images are
basicaly, graphical CAPTCHAs (Completely Automated Public
Turing Test to Tell Computers and Humans Apart). This
module gives you a basic interface to create such an image. The final
output is the actual graphic data, the mime type of the graphic and the
created random string. The module also has some “styles†that are
used to create the background (or foreground) of the image.
If you are an Authen::Captcha user, see GD::SecurityImage::AC
for migration from Authen::Captcha to GD::SecurityImage.
GD::SecurityImage is just an image generator. Not a captcha handler.
The validation of the generated graphic is left to your programming
taste.
