<br>Humans Apart") -- aquelas imagens contendo letras e números<br>distorcidos, que uma pessoa precisa digitar antes de se cadastrar,<br>para garantir que é realmente humana (e não um bot, por exemplo).<br><br>"About 60 million CAPTCHAs are solved by humans around the world
<br>every day. In each case, roughly ten seconds of human time are being<br>spent. Individually, that's not a lot of time, but in aggregate these<br>little puzzles consume more than 150,000 hours of work each day. What
<br>if we could make positive use of this human effort? reCAPTCHA does<br>exactly that by channeling the effort spent solving CAPTCHAs online<br>into "reading" books.<br><br>reCAPTCHA improves the process of digitizing books by sending words
<br>that cannot be read by computers to the Web in the form of CAPTCHAs<br>for humans to decipher."<br><br>Ou seja: ao invés de perder o tempo de usuário, o seu site contribui<br>para a digitalização de um livro -- uma palavra de cada vez.
<br><br>Outras vantagens:<br><br>"reCAPTCHA has the highest security standards.<br><br>reCAPTCHA is a Web service. That means that all the images are<br>generated and graded by our servers. In addition to the convenience
<br>that this provides (you don't have to run costly image generation<br>scripts on your own servers), this also provides an extra level of<br>protection: our CAPTCHAs can be automatically updated whenever a<br>security vulnerability is found."
<br><br>O reCAPTCHA é mantido pelos criadores originais do CAPTCHA, da<br>Carnegie Mellon University.<br><br><br>Em perl:<br><br> use Captcha::reCAPTCHA;<br><br> my $c = Captcha::reCAPTCHA->new;<br><br> # Output form
<br> print $c->get_html( 'your public key here' );<br><br> # Verify submission<br> my $result = $c->check_answer(<br> 'your private key here', $ENV{'REMOTE_ADDR'},<br> $challenge, $response
