In fact, I think integrating JCaptcha wasn't the best idea we ever had, it's slow, has unusable default output (I really can't read it), and has dependencies such as this. | | Alternatives welcome... | The only other captcha engine for java I know of is "the simple java captcha" (http://simplecaptcha.sourceforge.net/). I have no idea if it is faster than JCaptcha or if it needs a running X server too but at least the output seems more readable (I couldn't read JCaptcha output if my life would depend on it). However: an alternative to captchas could be asking simple math questions (like they do at jroller). Together with a tag that translates the numbers and the operand into iso & hex - e.g. 1+2 would be: &#x31&#59;&#x2b&#59;&#x32&#59; - this should be as save, cheaper to compute and much easier for users than barely readable captchas. Last but not least this "translator" tag could be used to obfuscate email addresses so they can be safely displayed and don't get harvested by spammers which seems to be a quite valuable addition to me ;). Please have a look at http://www.seowebsitepromotion.com/obfuscate_email.asp for a more detailed explanation! So what do you think about this?
