Description:
Perl extension for creating captcha's
Authen::Captcha provides an object oriented interface to captcha file creations. Captcha stands for Completely Automated Public Turing test to tell Computers and Humans Apart. A Captcha is a program that can generate and grade tests that: . - Most humans can pass. - Current computer programs can't pass. . The most common form is an image file containing distorted text, which humans are adept at reading, and computers (generally) do a poor job. This module currently implements that method.
