Supplied by: Giuseppe Leone <e-mail contact>

Generate and validate CAPTCHA verification images

This package can be used to generate and validate CAPTCHA validation images.

It can create an image in the PNG format displaying a random text. The text is stored in a session variable for later verification.

The class can also generate HTML to display the verification image and the inputs of a form on which the user must type the text in the image.

The class can verify whether the submitted form input text matches the text in the image.

All actions are recorded in a log stored as a class variable.

	2. KCAPTCHA		image verification

Supplied by: Sergei Kruglov <e-mail contact>

Generate CAPTCHA validation images with effects

This class can be used to generate CAPTCHA validation images with the verification text rendered with distortion.

It generates a random text using a list of allowed characters.

The text is rendered as an image with several effects to distort the characters and make it more difficult to guess by automated programs.

The text is rendered with fonts defined as images in the PNG format. So it does not need any PHP special font engine library extensions.

The generated image is served as the current script output either in JPEG, GIF or PNG formats.

	3. Verification Image		image verification

Supplied by: Rafael M. Dohms <e-mail contact>

Generate a verification image for validating forms

This class generates an image with random text to verify that a form was submitted by a real human being.

It adds some visual elements that are meant to confuse OCR (Optical Character Recognition) software, thus making it very difficult for robot scripts to determine the actual text that is displayed in the generated image.

Requires GD library compiled with PHP.
