that's a very rare antonym so i think the antonym of "inform": "keep in the dark"
i know it's an expression but there is no antonym for "inform" may be we can say "hide" i mean instead of saying " he informed me" "he hidden from me some informations " i am not sure from hide so if you are going to say it in a sentence i think it works but i am sure from "keep in the dark"
look there is a site called
encarta.msn.com
it contains synoynms and antonyms its a very good site if you wanna make sure
i hope that this would be benefit for you
