Concealment
Concealment devices or diversion safes are used to hide things for the purpose of secrecy or security. They are made from an ordinary household object such as a book, a soda can, a candle, a can, or something as small as a coin. The idea is that such an inconspicuous object would not be expected to contain anything of worth. Examples in espionage include dead drop spikes for transferring items to other people, and hollowed-out coins or hollowed out teeth for concealing something - such as microfilm or a suicide pill. Examples in smuggling include suitcases with false bottoms for hiding contraband. During World War II MI9 was responsible for creating many concealment devices for "escape aids" to assist prisoners of war to escape. Examples Ammunition Starting in the First World War and still continuing today, military personnel use ammunition casings to hide small amounts of critical information e.g. encryption/recognition codes or navigational grid references etc. The hiding pl ...

Secrecy
Secrecy is the practice of hiding information from certain individuals or groups who do not have the "need to know", perhaps while sharing it with other individuals. That which is kept hidden is known as the secret. Secrecy is often controversial, depending on the content or nature of the secret, the group or people keeping the secret, and the motivation for secrecy. Secrecy by government entities is often decried as excessive or in promotion of poor operation; excessive revelation of information on individuals can conflict with virtues of privacy and confidentiality. It is often contrasted with Transparency (social), social transparency. Secrecy can exist in a number of different ways: encoding or encryption (where mathematical and technical strategies are used to hide messages), true secrecy (where restrictions are put upon those who take part of the message, such as through Classified information, government security classification) and obfuscation, where secrets are hidd ...

Hidden Compartment
A hidden compartment or secret compartment is a compartment whose existence or access is not obvious at first glance, and can be used as a hiding place for objects or sometimes even for people. A hidden compartment where people can stay is usually referred to as a hidden room or secret room, and can range from parts of small wardrobes or closets under staircases to entire basements or even large mountain complexes. Hidden rooms are often accessed via a hidden door, which for example can be camouflaged as a bookshelf or a trapdoor in the floor. Hidden rooms can for example be used as a refuge, media room, larder or wine cellar. The term hidden compartment can also refer to smaller storage places for valuables and personal belongings in furniture (such as cabinet compartments), trap compartments in vehicles, false bottoms in containers, and various other concealment devices. History In the 1500s and 1600s, hidden rooms were created in British castles to hide Catholic pries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dead Drop
A dead drop or dead letter box is a method of espionage tradecraft used to pass items or information between two individuals (e.g., a case officer and an agent, or two agents) using a secret location. By avoiding direct meetings, individuals can maintain operational security. This method stands in contrast to the live drop, so-called because two persons meet to exchange items or information. Spies and their handlers have been known to perform dead drops using various techniques to hide items (such as money, secrets or instructions) and to signal that the drop has been made. Although the signal and location by necessity must be agreed upon in advance, the signal may or may not be located close to the dead drop itself. The operatives may not necessarily know one another or ever meet. Considerations The location and nature of the dead drop must enable retrieval of the hidden item without the operatives being spotted by a member of the public, the police, or other security forcesâ ...

Smuggling
Smuggling is the illegal transportation of objects, substances, information or people, such as out of a house or buildings, into a prison, or across an international border, in violation of applicable laws or other regulations. There are various motivations to smuggle. These include the participation in illegal trade, such as in the drug trade, illegal weapons trade, prostitution, human trafficking, kidnapping, exotic wildlife trade, art theft, heists, chop shops, illegal immigration or illegal emigration, tax evasion, import/export restrictions, providing contraband to prison inmates, or the theft of the items being smuggled. Smuggling is a common theme in literature, from Bizet's opera ''Carmen'' to the James Bond spy books (and later films) '' Diamonds Are Forever'' and '' Goldfinger''. Etymology The verb ''smuggle'', from Low German ''smuggeln'' or Dutch ''smokkelen'' (="to transport (goods) illegally"), apparently a frequentative formation of a word meaning "to sneak ...

False Bottom
A false bottom (or false back) is an internal partition in a container, typically at the bottom of a drawer, suitcase or similar item, enabling the concealment of objects from a cursory examination of the item's contents. A false bottom may be present if the internal dimensions of a container do not match its external dimensions after taking into account the thicknesses of constituent materials and structures used to build the object. The term false bottom can also refer to the deep scattering layer in the ocean, a phenomenon where a layer of marine organisms deep in the ocean can be mistaken by sonar for the seabed.Hersey JB and Backus RH (2005"Sound Scattering by Marine Organisms"In: M. N. Hill and A. R. Robinson (Eds)''Physical Oceanography'', Page 499, Harvard University Press. .

Radio Hidden In A Book
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hollow Nickel Case
The Hollow Nickel Case (or the Hollow Coin) was the FBI investigation that grew out of the discovery of a container disguised as a U.S. coin and containing a coded message, eventually found to concern espionage activities of William August Fisher ( Rudolf Ivanovich Abel) on behalf of the Soviet Union. Background On June 22, 1953, a newspaper boy (fourteen-year-old Jimmy Bozart), collecting for the ''Brooklyn Eagle'', at an apartment building at 3403 Foster Avenue in the New York City borough of Brooklyn, was paid with a nickel (U.S. five-cent piece) that felt too light to him. When he dropped it on the ground, it popped open, revealing that it contained microfilm. The microfilm contained a series of numbers. He told the daughter of a New York City Police Department officer, and that officer told a detective who in two days told an FBI agent about the strange nickel. After agent Louis Hahn of the FBI obtained the nickel and the microfilm, the agency tried to find out where t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eisenhower Dollar
The Eisenhower dollar was a one-dollar coin issued by the United States Mint from 1971 to 1978; it was the first coin of that denomination issued by the Mint since the Peace dollar series ended in 1935. The coin depicts President Dwight D. Eisenhower on the obverse, and on the reverse a stylized image honoring the 1969 Apollo 11 Moon mission based on the mission patch designed by astronaut Michael Collins. Both sides were designed by Frank Gasparro. It is the only large-size U.S. dollar coin whose circulation strikes contained no silver. In 1965, because of rises in bullion prices, the Mint began to strike copper-nickel clad coins instead of silver. No dollar coins had been issued in thirty years, but, beginning in 1969, legislators sought to reintroduce a dollar coin into commerce. After Eisenhower died that March, there were a number of proposals to honor him with the new coin. While these bills generally commanded wide support, enactment was delayed by a dispute over wheth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milling Machine
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done by varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances. Milling can be done with a wide range of machine tools. The original class of machine tools for milling was the milling machine (often called a mill). After the advent of computer numerical control (CNC) in the 1960s, milling machines evolved into ''machining centers'': milling machines augmented by automatic tool changers, tool magazines or carousels, CNC capability, coolant systems, and enclosures. Milling centers are generally classified as vertical machining centers (VMCs) or horizontal machining centers (HMCs). The integra ...

Saxitoxin
Saxitoxin (STX) is a potent neurotoxin and the best-known paralytic shellfish toxin (PST). Ingestion of saxitoxin by humans, usually by consumption of shellfish contaminated by toxic algal blooms, is responsible for the illness known as paralytic shellfish poisoning (PSP). The term saxitoxin originates from the genus name of the butter clam (''Saxidomus'') from which it was first isolated. But the term saxitoxin can also refer to the entire suite of more than 50 structurally related neurotoxins (known collectively as "saxitoxins") produced by protists, algae and cyanobacteria which includes saxitoxin itself (STX), neosaxitoxin (NSTX), gonyautoxins (GTX) and decarbamoylsaxitoxin (dcSTX). Saxitoxin has a large environmental and economic impact, as its presence in bivalve shellfish such as mussels, clams, oysters and scallops frequently leads to bans on commercial and recreational shellfish harvesting in many temperate coastal waters around the world including the Northeastern and W ...
