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.

"Faced with this process of globalization, most governments appear to lack the tools required for facing up to the pressure from important media changes. The new global order is viewed as a daunting challenge, and it most often results in reactions of introversion, withdrawal and narrow assertions of national identity. At the same time, many developing countries seize the opportunity represented by globalization to assert themselves as serious players in the global communications market."
(UNESCO, World Communication Report)
The big hope of the South is that the Internet will close the education gap and economic gap, by making education easier to achieve. But in reality the gap is impossible to close, because the North is not keeping still, but developing itself further and further all the time; inventing new technologies that produce another gap each. The farmer's boy sitting in the dessert and using a cellular telephone and a computer at the same time is a sarcastic picture - nothing else.
Still, the so called developing countries regard modern communication technologies as a tremendous chance - and actually: which other choice is there left?

FTP enables the transfer of files (text, image, video, sound) to and from other remote computers connected to the Internet.
The WAP (Wireless Application Protocol) is a specification for a set of communication protocols to standardize the way that wireless devices, such as cellular telephones and radio transceivers, can be used for Internet access, including
While Internet access has been possible in the past, different manufacturers have used different technologies. In the future, devices and service systems that use WAP will be able to interoperate.
