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. |

Racism on the Internet The internet can be regarded as a mirror of the variety of interests, attitudes and needs of human kind. Propaganda and disinformation in that way have to be part of it, whether they struggle for something good or evil. But the classifications do no longer function. During the last years the internet opened up a new source for racism as it can be difficult to find the person who gave a certain message into the net. The anarchy of the internet provides racists with a lot of possibilities to reach people which they do not possess in other media, for legal and other reasons. In the 1980s racist groups used mailboxes to communicate on an international level; the first ones to do so were supposedly the A complete network of anti-racist organizations, including a high number of websites are fighting against racism.

Palm recognition In palm recognition a 3-dimensional image of the hand is collected and compared to the stored sample. Palm recognition devices are cumbersome artefacts (unlike fingerprint and iris recognition devices) but can absorb perform a great amount of identification acts in a short time. They are therefore preferably installed in situations where a large number of people is identified, as in airports. |

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 According to |

Content as Transport Medium for Values and Ideologies With the dissemination of their content commercial media are among other things also able to transport values and ideologies. Usually their programming reflects society's dominant social, political, ethical, cultural and economical values. A critical view of the prevalent ideologies often is sacrificed so as not to offend the existing political elites and corporate powers, but rather satisfy shareholders and advertisers. With most of the worlds content produced by a few commercial media conglomerates, with the overwhelming majority of companies (in terms of revenue generation) concentrated in Europe, the U.S., Japan and Australia there is also a strong flow of content from the 'North-West' to the 'South-East'. Popular culture developed in the world's dominant commercial centers and Western values and ideologies are so disseminated into the most distant corners of the earth with far less coming back. |

Microsoft Corporation Founded by Bill Gates and Paul Allen and headquartered in Redmond, USA, Microsoft Corporation is today's world-leading developer of personal-computer software systems and applications. As MS-DOS, the first operating system released by Microsoft, before, Windows, its successor, has become the de-facto standard operating system for personal computer. According to critics and following a recent court ruling this is due to unfair competition. For more detailed information see the Encyclopaedia Britannica: |

RSA The best known of the two-key cryptosystems developed in the mid-1980s is the Rivest-Shamir-Adleman (RSA) cryptoalgorithm, which was first published in April, 1977. Since that time, the algorithm has been employed in the most widely-used Internet electronic communications encryption program, |

CNN CNN is a U.S.-TV-enterprise, probably the world's most famous one. Its name has become the symbol for the mass-media, but also the symbol of a power that can decide which news are important for the world and which are not worth talking about. Every message that is published on CNN goes around the world. The Gulf War has been the best example for this until now, when a CNN-reporter was the one person to do the countdown to a war. The moments when he stood on the roof of a hotel in Baghdad and green flashes surrounded him, went around the world. |
