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.

Protecting speech on the global data networks attracts an increasing attention. The efforts and the corresponding abilities of governmental authorities, corporations and copyright enforcement agencies are countered by similar efforts and abilities of researchers and engineers to provide means for anonymous and uncensored communication, as Freenet, Free Haven and Publius. All three of them show a similar design. Content is split up and spread on several servers. When a file is requested, the pieces are reassembled. This design makes it difficult to censor content. All of these systems are not commercial products.
The most advanced system seems to be Publius. Because of being designed by researchers and engineers at the prestigious

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:

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.

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

The MIT (Massachusetts Institute of Technology) is a privately controlled coeducational institution of higher learning famous for its scientific and technological training and research. It was chartered by the state of Massachusetts in 1861 and became a land-grant college in 1863. During the 1930s and 1940s the institute evolved from a well-regarded technical school into an internationally known center for scientific and technical research. In the days of the Great Depression, its faculty established prominent research centers in a number of fields, most notably analog computing (led by
