Data entry - prevent ctrl-v

Data entry - prevent ctrl-v

  
Guys,
How do i prevent paste on a data entry field i.e. i have two fields 1) email address 2) confirm email address i need the recipient to type in both values and not use the ctrl-v (paste) option
Thanks
check this fiddle

$(document).ready(function() {
	$('#email2').bind('copy paste cut',function(e) { 
	 e.preventDefault(); //disable cut,copy,paste
	 alert('cut,copy & paste options are disabled !!');
	 });
	});
As a user I do that copy/paste often and I really can't remember an app not allowing me that...
It breaks the purpose of asking to confirm email address! Such a small detail but it can solve many headaches :)
