Secure login var pass to php

I have a html pages in which user is logged on
in one page he can use swf movies but that movies need to know which user it is
so I need to pass vars to swf (username), but that can be problem
because anyone could open swf with submitting username to swf

so I need somehow secure user var pass to swf at start

if somebody have experience on this I would like to hear it
if you have any questions please reply…

thanx in advance
