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.

One of the most important advances in the development of computer hardware in the late 1960s and early 1970s was the invention of the
Another type of computer developed at the time was the minicomputer. It profited from the progresses in microelectronics and was considerably smaller than the standard mainframe, but, for instance, powerful enough to control the instruments of an entire scientific laboratory. Furthermore

In the 1960s and 1970s a multitude of AI programs were developed, most notably SHRDLU. Headed by Marvin Minsky the MIT's research team showed, that when confined to a small subject matter, computer programs could solve spatial and logic problems. Other progresses in the field of AI at the time were: the proposal of new theories about

With the increased ease of the reproduction and transmission of unauthorized copies of digital works over electronic networks concerns among the copyright holder community have arisen. They fear a further growth of copyright piracy and demand adequate protection of their works. A development, which started in the mid 1990s and considers the copyright owner's apprehensions, is the creation of

In parallel to the deregulation of markets, there has been a trend towards large-scale mergers which ridicules dreams of increased competition.
Recent mega-mergers and acquisitions include
SBC Communications - Ameritech, $ 72,3 bn
Bell Atlantic - GTE, $ 71,3
AT&T - Media One, $ 63,1
AOL - Time Warner, $ 165 bn
MCI Worldcom - Spring, $ 129 bn
The total value of all major mergers since the beginnings of the 1990s has been 20 trillion Dollars, 2,5 times the size of the USA's GIP.
The AOL- Time Warner reflects a trend which can be observed everywhere: the convergence of the ICT and the content industries. This represents the ultimate advance in complete market domination, and a alarming threat to independent content.
"Is TIME going to write something negative about AOL? Will AOL be able to offer anything other than CNN sources? Is the Net becoming as silly and unbearable as television?"

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. For example:

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.

The Enigma Encryption Machine was famous for its insecurities as for the security that it gave to German ciphers. It was broken, first by the Poles in the 1930s, then by the British in World War II.

Artificial Intelligence is concerned with the simulation of human thinking and emotions in information technology. AI develops "intelligent systems" capable, for example, of learning and logical deduction. AI systems are used for creatively handling large amounts of data (as in data mining), as well as in natural speech processing and image recognition. AI is also used as to support

Harold. D. Lasswell (* 1902) studied at the London School of Economics. He then became a professor of social sciences at different Universities, like the University of Chicago, Columbia University, and Yale University. He also was a consultant for several governments. One of Lasswell's many famous works was Propaganda Technique in World War. In this he defines propaganda. He also discussed major objectives of propaganda, like to mobilize hatred against the enemy, to preserve the friendship of allies, to procure the co-operation of neutrals and to demoralize the enemy.
