Iris recognition

Iris recognition relies upon the fact that every individuals retina has a unique structure. The iris landscape is composed of a corona, crypts, filaments, freckles, pits radial furrows and striatations. Iris scanning is considered a particularly accurate identification technology because the characteristics of the iris do not change during a persons lifetime, and because there are several hundred variables in an iris which can be measured. In addition, iris scanning is fast: it does not take longer than one or two seconds.

These are characteristics which have made iris scanning an attractive technology for high-security applications such as prison surveillance. Iris technology is also used for online identification where it can substitute identification by password. As in other biometric technologies, the use of iris scanning for the protection of privacy is a two-edged sword. The prevention of identity theft applies horizontally but not vertically, i.e. in so far as the data retrieval that accompanies identification and the data body which is created in the process has nothing to do with identity theft.

1950: The Turing Test

Alan Turing, an English mathematician and logician, advocated the theory that eventually computers could be created that would be capable of human thought. To cut through the long philosophical debate about exactly how to define thinking he proposed the "imitation game" (1950), now known as Turing test. His test consisted of a person asking questions via keyboard to both a person and an intelligent machine within a fixed time frame. After a series of tests the computers success at "thinking" could be measured by its probability of being misidentified as the human subject. Still today Turing's papers on the subject are widely acknowledged as the foundation of research in artificial intelligence.

The British Propaganda Campaign in World War I

The British set up a unique system for propaganda, involving GB, the USA and all the colonies. Most different agencies and civilians worked together, the civilians not always knowing about the machinery behind.
During the first years of the war the main goal was to achieve a U.S.-entry to the war on Britain's side of the battle. All propaganda was working on this, which meant to destroy Germany's reputation and create dark stereotypes about them, which was an easy task as the Germans were not only fatally unlucky but also very weak in propaganda. At the same time the U.S.-citizens' opinion about the war had to be influenced. The most promising way to do so was by starting with the men in power.

One of the most beloved tools at that time was the use of atrocity stories; and most popular among the masses were cartoons, furthermore posters, an element perfectioned by the USSR in World War I and II, and movies.

The particular thing was that British propaganda finally had an effect on the German population. Soldiers at the front and people at home received the disinformation messages, mostly pamphlets that had been dropped by aeroplanes or balloons.
Together with the development of the fightings turning against the Germans this kind of propaganda was able to discourage the people and make the German government lose its power of propaganda.
"Allied propaganda had caused a collapse of morale at home." (Taylor, Munitions of the Mind, p. 188)

After all this success it is hardly understandable that the British committed a huge error right after the war, an error that had bad consequences for the next war: being regarded as a tool of war and therefore regarded as inappropriate for times of peace, the propaganda institutions were closed. At about the same time similar ones were built up in Germany - first of all on paper, in Hitler's book Mein Kampf, whose author was an admirer of the British propaganda machine in World War I and decided to perfect it in his own country.

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.

Vacuum tube

The first half of the 20th century was the era of the vacuum tube in electronics. This variety of electron tube permitted the development of radio broadcasting, long-distance telephony, television, and the first electronic digital computers. These early electronic computers were, in fact, the largest vacuum-tube systems ever built. Perhaps the best-known representative is the ENIAC (Electronic Numerical Integrator and Computer, completed in 1946).

Viacom

One of the largest and foremost communications and media conglomerates in the
world. Founded in 1971, the present form of the corporation dates from 1994 when Viacom Inc., which owned radio and television stations and cable television programming services and systems, acquired the entertainment and publishing giant Paramount Communications Inc. and then merged with the video and music retailer Blockbuster Entertainment Corp. Headquarters are in New York City.

atbash

Atbash is regarded as the simplest way of encryption. It is nothing else than a reverse-alphabet. a=z, b= y, c=x and so on. Many different nations used it in the early times of writing.

Hieroglyphs are pictures, used for writing in ancient Egypt. First of all those pictures were used for the names of kings, later more and more signs were added, until a number of 750 pictures
