Mŕtva schránka
Mŕtva schránka je metóda predávania informácií, inštrukcií, alebo iných vecí špionážneho charakteru, využívajúca nejaké dohodnuté miesto, pričom osoby zúčastňujúce sa danej transakcie (napr. dôstojník a agent, alebo dvaja agenti) spolu neprídu do kontaktu. Mŕtve schránky sa používajú od konca 60. rokov minulého storočia.
Mŕtva schránka je obvykle vodovzdorná krabička, do ktorej je možné uložiť peniaze, inštrukcie, tajné správy, dokumenty, mapy, mikrofilmy a iné veci. Schránka býva umiestnená na verejne dostupnom mieste, často býva bežnou súčasťou okolia; napr. nefunkčná poštová schránka, falošná tehla v múre, dutina stromu atď. Pokiaľ je schránka naplnená, druhá strana transakcie je upozornená nejakým dohodnutým signálom, napr. značkou na stene, nalepením poštovej známky na dohodnutom mieste, vyložením kvetináča na parapet okna...
Nepripomína to geocaching?

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 agent, or two agents) using a secret location, thus not requiring them to meet directly and thereby maintaining operational security. The method stands in contrast to the live drop, so called because two persons meet to exchange items or information..
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 forces—therefore, common everyday items and behavior are used to avoid arousing suspicion. Any hidden location could serve, although often a cut-out device is used, such as a loose brick in a wall, a (cut-out) library book, or a hole in a tree..
The dead drop spike is a concealment device similar to a microcache. It has been used since the late 1960s to hide money, maps, documents, microfilm, and other items. The spike is water- and mildew-proof and can be pushed into the ground or placed in a shallow stream to be retrieved at a later time. Signaling devices can include a chalk mark on a wall, a piece of chewing-gum on a lamppost, or a newspaper left on a park bench. Alternately, the signal can be made from inside the agent's own home, by, for example, hanging a distinctively-colored towel from a balcony, or placing a potted plant on a window sill where it is visible to anyone on the street..
Does it looks like geocaching?
