Virtual cartels; mergers

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?"

(Detlev Borchers, journalist)

Biometrics applications: gate keeping

Identity has to do with "place". In less mobile societies, the place where a person finds him/herself tells us something about his/her identity. In pre-industrial times, gatekeepers had the function to control access of people to particular places, i.e. the gatekeepers function was to identify people and then decide whether somebody's identity would allow that person to physically occupy another place - a town, a building, a vehicle, etc.

In modern societies, the unambiguous nature of place has been weakened. There is a great amount of physical mobility, and ever since the emergence and spread of electronic communication technologies there has been a "virtualisation" of places in what today we call "virtual space" (unlike place, space has been a virtual reality from the beginning, a mathematical formula) The question as to who one is no longer coupled to the physical abode. Highly mobile and virtualised social contexts require a new generation of gatekeepers which biometric technology aims to provide.

Proxy Servers

A proxy server is a server that acts as an intermediary between a workstation user and the Internet so that security, administrative control, and caching service can be ensured.

A proxy server receives a request for an Internet service (such as a Web page request) from a user. If it passes filtering requirements, the proxy server, assuming it is also a cache server, looks in its local cache of previously downloaded Web pages. If it finds the page, it returns it to the user without needing to forward the request to the Internet. If the page is not in the cache, the proxy server, acting as a client on behalf of the user, uses one of its own IP addresses to request the page from the server out on the Internet. When the page is returned, the proxy server relates it to the original request and forwards it on to the user.
