- Fixed: Big-endian captcha issues has been tried and tested on both little and big endian systems. Now auto-works on both.
- Fixed: Big Endian issues with captcha system. Added a test which attempts to auto-detect the systems big-endian status. Needs testing on a big-endian system.
freeCap is designed to be as customisable as possible. There are several variables you can change to make the text more readable:
- Change the
bg_typeto 0, 1 or 2
- Reduce the chunk factor
- Use more readable fonts
- Alter the fade factor
But bear in mind that increased human readability means decreased OCR-resistance. On the other hand, a CAPTCHA is more often simply a deterrent and the actual theoretical security matters little.
Nothing, my suggestion for accessibility is to allow people to enter their details without passing the CAPTCHA, but send non-captcha’ed submittals to a ‘pending’ queue for manual review. It’s a much much simpler solution that still leaves the site accessible.
'captcha_new_comment' => 1, 'captcha_new_page' => 1, 'captcha_edit_page' => 1, 'captcha_registration' => 1,
