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.
|
|
|
|
This module is just an image generator. Not a captcha handler. The
|
|
validation of the generated graphic is left to your programming
|
|
taste. But there are some captcha handlers for several Perl
|
|
FrameWorks. If you are an user of one of these frameworks, see
|
|
"GD::SecurityImage Implementations" in "SEE ALSO" section for
|
|
information.
