Face recognition In order to be able to recognize a person, one commonly looks at this persons face, for it is there where the visual features which distinguish one person from another are concentrated. Eyes in particular seem to tell a story not only about who somebody is, but also about how that persons feel, where his / her attention is directed, etc. People who do not want to show who they are or what is going on inside of them must mask themselves. Consequently, face recognition is a kind of electronic unmasking. "Real" face-to-face communication is a two-way process. Looking at somebody's face means exposing ones own face and allowing the other to look at oneself. It is a mutual process which is only suspended in extraordinary and voyeuristic situations. Looking at somebody without being looked at places the person who is visually exposed in a vulnerable position vis-à-vis the watcher. In face recognition this extraordinary situation is normal. Looking at the machine, you only see yourself looking at the machine. Face biometrics are extracted anonymously and painlessly by a mask without a face. Therefore the resistance against the mass appropriation of biometrical data through surveillance cameras is confronted with particular difficulties. The surveillance structure is largely invisible, it is not evident what the function of a particular camera is, nor whether it is connected to a face recognition system. In a protest action against the face recognition specialist Visionics, the Surveillance Camera Players therefor adopted the strategy of re-masking: in front of the cameras, they perfomed the play "The Masque of the Red Death" an adaption of Edgar Allen Poe's classic short story by Art Toad. According to Visionics, whose slogan is "enabling technology with a mass appeal", there are alrady 1.1 bn digitised face images stored on identification data banks world wide. When combined with wide area surveillance camera networks, face recognition is capable of creating a transparent social space that can be controlled by a depersonalised, undetected and unaccountable centre. It is a technology, of which the surveillance engeneers of sunken totalitarian regimes may have dreamt, and one that today is being adopted by democratic governments.

Timeline 1900-1970 AD 1913 the wheel cipher gets re-invented as a strip 1917 William Frederick Friedman starts working as a cryptoanalyst at Riverbank Laboratories, which also works for the U.S. Government. Later he creates a school for military cryptoanalysis - an AT&T-employee, Gilbert S. Vernam, invents a polyalphabetic cipher machine that works with random-keys 1918 the Germans start using the ADFGVX-system, that later gets later by the French Georges Painvin - Arthur Scherbius patents a ciphering machine and tries to sell it to the German Military, but is rejected 1919 Hugo Alexander Koch invents a rotor cipher machine 1921 the Hebern Electric Code, a company producing electro-mechanical cipher machines, is founded 1923 Arthur Scherbius founds an enterprise to construct and finally sell his Enigma machine for the German Military late 1920's/30's more and more it is criminals who use cryptology for their purposes (e.g. for smuggling). Elizabeth Smith Friedman deciphers the codes of rum-smugglers during prohibition regularly 1929 Lester S. Hill publishes his book Cryptography in an Algebraic Alphabet, which contains enciphered parts 1933-1945 the Germans make the Enigma machine its cryptographic main-tool, which is broken by the Poles Marian Rejewski, Gordon Welchman and Alan Turing's team at Bletchley Park in England in 1939 1937 the Japanese invent their so called Purple machine with the help of Herbert O. Yardley. The machine works with telephone stepping relays. It is broken by a team of William Frederick Friedman. As the Japanese were unable to break the US codes, they imagined their own codes to be unbreakable as well - and were not careful enough. 1930's the Sigaba machine is invented in the USA, either by W.F. Friedman or his colleague Frank Rowlett - at the same time the British develop the Typex machine, similar to the German Enigma machine 1943 Colossus, a code breaking computer is put into action at Bletchley Park 1943-1980 the cryptographic Venona Project, done by the NSA, is taking place for a longer period than any other program of that type 1948 Shannon, one of the first modern cryptographers bringing mathematics into cryptography, publishes his book A Communications Theory of Secrecy Systems 1960's the Communications-Electronics Security Group (= CESG) is founded as a section of Government Communications Headquarters (= GCHQ) late 1960's the IBM Watson Research Lab develops the Lucifer cipher 1969 James Ellis develops a system of separate public-keys and private-keys

Movies as a Propaganda- and Disinformation-Tool in World War I and II Movies produced in Hollywood in 1918/19 were mainly anti-German. They had some influence but the bigger effect was reached in World War II-movies. The first propaganda movie of World War II was British. At that time all films had to pass censoring. Most beloved were entertaining movies with propaganda messages. The enemy was shown as a beast, an animal-like creature, a brutal person without soul and as an idiot. Whereas the own people were the heroes. That was the new form of atrocity. Leni Riefenstahl was a genius in this respect. Her movies still have an incredible power, while the majority of the other movies of that time look ridiculous today. The combination of light and shadow, the dramatic music and the mass-scenes that resembled ballet, had its effect and political consequences. Some of the German movies of that period still are on the index. U.S.-President Theodore Roosevelt considered movies the best propaganda-instrument, as they are more subtle than other tools. In the late twenties, movies got more and more important, in the USSR, too, like Sergei Eisenstein demonstrated with his movies. Historic events were changed into symbolism, exactly the way propaganda should function. It was disinformation - but in its most artistic form, especially in comparison to most U.S.- and European movies of that time.
