Replace built-in CAPTCHA support with reCAPTCHA, which provides an audio CAPTCHA for users with vision disabilities + supports digitization of public works.

Add to WAL. Make available in OJS, OCS, and Harvester.

Just a quick note here. When this is implemented, it would be good to allow JMs etc. to be able to choose between reCaptcha and the current one. I've actually noticed far fewer successful spam registrations using the default captcha on the forum, as opposed to the reCaptcha option.

Introduces new config parameters that need to be added to the captcha section in config.inc.php if upgrading an existing installation:

; Whether to use reCaptcha instead of default Captcha
recaptcha = off

; Public key for reCaptcha (see http://www.google.com/recaptcha)
; recaptcha_public_key = your_public_key

; Private key for reCaptcha (see http://www.google.com/recaptcha)
; recaptcha_private_key = your_private_key

Still need to port to OHS.
Comment 6 Michael Felczak 2011-03-19 13:48:35 PDT
OHS does not include public user registration. Not porting.
