[TAC] Custom Image Captcha - Product specifications

Custom Image Captcha makes it much harder for bots to solve your Captchas, while at the same time making it easier for users. It also allows you to add an extra customized touch to your forum.

Many of the popular CAPTCHA systems fail, simply because they are popular, and so become an easy target for bots to train against. However, Custom Image Captcha can not suffer this same fate, since every forum can use unique image sets.

Features

• Upload multiple custom CAPTCHA images (customised for your site).
• Supports multiple answers per image.
• The CAPTCHA images are displayed randomly.
• For every custom image you upload, 320,000 different possible versions are available to be shown to the user (different resolution, positioning etc), making them harder for bots to crack.
• Stats on each Image: How Many Humans Passed It Vs How many Humans Failed it*.
• Stats on each Image: How Many Bots Passed It Vs How many Bots Failed it*.
• Default example images are provided (and should be deleted and replaced with your own custom set or a set provided to you).
• Custom Image Captcha is available in all CAPTCHA areas (replacing QA CAPTCHA / ReCAPTCHA where applicable).
• The CAPTCHA images can not be linked to directly with the public UUID (unique identifier), as the image UUID is deactivated after 24hrs.
• If you have good ideas / images for CAPTCHA, you can export the sets and possibly provide them to others.
• A safe import mechanism via the ACP is provided.
• Exported sets are compatible with phpMyAdmin (but this should not be needed, unless the set is very large, since the built-in import mechanim can upload your sets).
• CAPTCHA attempts (passed / failed) logs are recorded in the Admin Control Panel -> Tools. This can give you information more detailed information about your CAPTCHA set (such as the human answers when they fail the CAPTCHA).
