将form_validation调用设为私有

我有一个CodeIgniter验证码,正在使用Codeigniter表单验证和规则的回调函数进行验证。以下是我的注册控制器内部的两种方法:

 public function index(){   
    $this->form_validation->set_rules('user_name' , 'Username' , 'trim|required|max_length[32]'); 
    $this->form_validation->set_rules('captcha' , 'Captcha' , 'trim|required|max_length[32]|callback_check_captcha');
    $this->form_validation->set_rules('password', 'Password','trim|required|min_length[5]|max_length[12]');
    $this->form_validation->set_rules('confirm_password', 'Confirm Password','trim|required|min_length[5]|max_length[12]|matches[password]');
    $this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email');
    if ($this->form_validation->run()==FALSE){
    //Captcha code 

回叫是:

   private function check_captcha($captcha_input){
    // First, delete old captchas
    $expiration = time() - 7200; // Two hour limit
    $this->db->where('captcha_time < ', $expiration)
            ->delete('captcha');

    // Then see if a captcha exists:
    $sql = 'SELECT COUNT(*) AS count FROM captcha WHERE word = ? AND ip_address = ? AND captcha_time > ?';
    $binds = array($captcha_input, $this->input->ip_address(), $expiration);
    $query = $this->db->query($sql, $binds);
    $row = $query->row();
    if ($row->count == 0){
        $this->form_validation->set_message('check_captcha', 'Captcha Fail');
        return FALSE;
    }else {
        return TRUE;
    }

}

问题是用户将可以使用URL(http://[::1]/ci/register/check_captcha)访问回调函数。尽管如此,在这种情况下,什么都没有发生,但尽管如此,我还是想学会防止这种情况发生。通常,在CI中,我将功能私有化,不允许用户UR1访问。如果我尝试将check_captcha函数设为私有,我会得到

  

消息:从上下文'CI_Form_validation中调用私有方法Register :: check_captcha()

我知道form_validation正在从寄存器类外部调用回调。有人可以告诉我在这种情况下如何限制对控制器的URl访问吗?
