The captcha : vista aperto

I input "vista", then I click button login. It's success to login. Should it not succeed to login, because the captcha incomplete.

whether the process is so? or is there a way to fix?

I using library recaptcha. I using codeigniter framework. My library is like this : 

class Google_recaptcha
{
    function check_captcha($private_key, $remote_ip, $challenge, $response)
    {   
        if (!preg_match('/[^A-Za-z0-9\s]/', $response))
        {
            $CI =& get_instance();
            $CI->load->library('scurl');
            $array['site'] = 'http://www.google.com/recaptcha/api/verify';
            $array['post'] = 'privatekey='.$private_key.'&remoteip='.$remote_ip.'&challenge='.$challenge.'&response='.$response;
            $array['referer'] = '';
            $array['method'] = 'POST';

            $response = $CI->scurl->scurl($array);
            $response = explode("\n", $response);
        }
        else
            $response = array('false');

        return $response;
    }
}

Do not use those old script. Try reCaptcha. It is much better. Just click authorization without typing anything. Sometimes you have to choose one kind of picture. From Google's web API you can control security level. https://www.google.com/recaptcha/intro/index.html
