Sorry, not a single word, but an applicable expression, "pull the wool over someone's eyes", is used to keep someone from knowing something, as illustrated in this example (and definition) from TheFreeDictionary.com:
Definition: to deceive someone in order to prevent them from knowing what you are really doing.
Example: "Don't let insurance companies pull the wool over your eyes - ask for a list of all the hidden charges."
