What is Securimage?
|
| 59 |
|
| 60 |
+
Securimage is a PHP class that is used to generate and validate CAPTCHA
|
| 61 |
+
images.
|
| 62 |
+
|
| 63 |
+
The classes uses an existing PHP session or creates its own if
|
| 64 |
+
none is found to store the CAPTCHA code. In addition, a database can be
|
| 65 |
+
used instead of session storage.
|
| 66 |
+
|
| 67 |
+
Variables within the class are used to control the style and display of
|
| 68 |
+
the image. The class uses TTF fonts and effects for strengthening the
|
| 69 |
+
security of the image.
|
| 70 |
+
|
| 71 |
+
It also creates audible codes which are played for visually impared users.
