How about an id that is actually unique?

perl -MData::UUID -le 'print Data::UUID->new->create_str'

With CGI.pm- 

use strict;
use warnings;
use CGI qw(:standard);
use Data::UUID;

print
    header(),
    start_html(),
    h1("MAI FORMZ"),
    start_form(),
    textfield(-name => "testing"),
    hidden(-name => "s3cr37", -value => Data::UUID->new->create_str),
    end_form(),
    end_html();

Hidden fields are hackable. So don't count on it being a secret or something the user can't twiddle.
