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. |

It is always the others Disinformation is supposed to be something evil, something ethically not correct. And therefore we prefer to connect it to the past or to other political systems than the ones in the Western hemisphere. It is always the others who work with disinformation. The same is true for propaganda. Even better, if we can refer it to the past: A war loses support of the people, if it is getting lost. Therefore it is extremely important to launch a feeling of winning the war. Never give up emotions of victory. Governments know this and work hard on keeping the mood up. The Germans did a very hard job on that in the last months of World War II. But the in the 1990s disinformation- and propaganda-business came back to life (if it ever had gone out of sight) through Iraq's invasion of Kuwait and the reactions by democratic states. After the war, reports made visible that not much had happened the way we had been told it had happened. Regarded like this the Gulf War was the end of the |

Punch card, 1801 Invented by Joseph Marie Jacquard, an engineer and architect in Lyon, France, the punch cards laid the ground for automatic information processing. For the first time information was stored in binary format on perforated cardboard cards. In 1890 Hermann Hollerith used Joseph-Marie Jacquard's punch card technology for processing statistical data retrieved from the US census in 1890, thus speeding up data analysis from eight to three years. His application of Jacquard's invention was also used for programming computers and data processing until electronic data processing was introduced in the 1960's. - As with Paper tapes are a medium similar to Jacquard's punch cards. In 1857 Sir Charles Wheatstone applied them as a medium for the preparation, storage, and transmission of data for the first time. By their means, telegraph messages could be prepared off-line, sent ten times quicker (up to 400 words per minute), and stored. Later similar paper tapes were used for programming computers. |
