To go "undercover" (that is, to go on an undercover operation) is to avoid detection by the object of one's observation, and especially to disguise one's own identity (or use an assumed identity) for the purposes of gaining the trust of an individual or organization in order to learn or confirm confidential information, or to gain the trust of targeted individuals to gather information or evidence. Undercover operations are traditionally employed by law enforcement agencies and private investigators; those in such roles are commonly referred to as undercover agents.
