Examples in espionage include dead drop spikes for transferring items to other people, and hollowed-out coins or teeth for concealing suicide pills. Examples in smuggling include suitcases with false bottoms for hiding contraband. The picture at right shows a hollow container, fashioned to look like an Eisenhower dollar, which is still used today to hide and send messages or film without being detected. Because it resemb ...

An individual needs a security clearance for access and other protection methods, such a ...

Preservation of secrets is one of the goals of information security. Techniques used include physical security and cryptography. The latter depends on the secrecy of cryptographic keys. Many believe that security technology can be more effective if it itself is not kept secret. See Full disclosure, Kerckhoffs' law, Security through obscurity.

Organizations, ranging from multi-national for profit corporations to nonprofit charities, keep secrets for competitive advantage, to meet legal requirements, or, in some cases, to conceal nefarious behavior.

Espionage is the practice of obtaining secrets (spying) from rivals or enemies for military, political, or economic advantage. It is usually thought of as part of an institutional effort (i.e., governmental or corporate intelligence). The definition has been restricted to a state spying on potential or actual enemies, primarily for military purposes, but this has been extended to spying involving corporations, known specifically as industrial espionage. Many nations routinely spy on both their enemies, and allies, although they ...

Since not much is publicly known about real-life secret agents, the popular conception of the secret agent has been formed largely by 20th and 21st century literature and cinema. Similar to the character of the private eye, the secret agent is usually a loner, sometimes amoral, an existential hero operating outside the everyday constraints of society. James Bond, the protagonist of Ian Fleming's novels who went on to spawn an extremely successful film franchise, is probably the most famous fictional secret agent of all. Another is the ...
