Disguise

v. hide, conceal, impersonate, camouflage

n. costume that hides one's identity; concealment

Deception is the act of convincing another to believe information that is not true.Deception involves concepts like propaganda, distraction and concealment. Fiction, while sometimes manipulative, is not a deception unless it is portrayed as the whole truth; not to be confused with half-truths.In many cases it is difficult to distinguish deception from providing unintentionally wrong information. One of the reasons for this is that a person or an entire organization may be self-deceived.
