This is the fingerprint method:

public static function fingerprint() {

    // custom fingerprint callback
    if(is_callable(static::$fingerprint)) {
      return call(static::$fingerprint);
    } 

    if(!r::cli()) {
      return sha1(Visitor::ua() . (ip2long($_SERVER['REMOTE_ADDR']) & ip2long('255.255.0.0')));      
    } else {
      return '';
    }
  }

So, if no custom fingerprint is used, the fingerprint is created like this:

 return sha1(Visitor::ua() . (ip2long($_SERVER['REMOTE_ADDR']) & ip2long('255.255.0.0')));

In your custom fingerprint, you can do whatever you want, return a string or return only parts of the above, e.g.

return sha1(Visitor::ua());

or whatever works for you.
