Object based Captchas

Published by at under internet,security

If traditional captchas are becoming more easy to crack with OCR software, I wonder if anyone has thought of doing a captcha where you identify the object in the image?  It seems that it would be significantly harder than recognizing text for an automated system.  If anything, it would at least spur research into object recognition algorithms which could be used for automated photo tagging on Flickr.
