Virtual cartels, oligopolistic structures

Global networks require global technical standards ensuring the compatibility of systems. Being able to define such standards makes a corporation extremely powerful. And it requires the suspension of competitive practices. Competition is relegated to the symbolic realm. Diversity and pluralism become the victims of the globalisation of baroque sameness.

The ICT market is dominated by incomplete competition aimed at short-term market domination. In a very short time, new ideas can turn into best-selling technologies. Innovation cycles are extremely short. But today's state-of-the-art products are embryonic trash.

    According to the Computer and Communications Industry Association, Microsoft is trying to aggressively take over the network market. This would mean that AT&T would control 70 % of all long distance phone calls and 60 % of cable connections.



    AOL and Yahoo are lone leaders in the provider market. AOL has 21 million subscribers in 100 countries. In a single month, AOL registers 94 million visits. Two thirds of all US internet users visited Yahoo in December 1999.



    The world's 13 biggest internet providers are all American.



    AOL and Microsoft have concluded a strategic cross-promotion deal. In the US, the AOL icon is installed on every Windows desktop. AOL has also concluded a strategic alliance with Coca Cola.

Challenges for Copyright by ICT: Introduction

Traditional copyright and the practice of paying royalties to the creators of intellectual property have emerged with the introduction of the printing press (1456). Therefore early copyright law has been tailored to the technology of print and the (re) production of works in analogue form. Over the centuries legislation concerning the protection of intellectual property has been adapted several times in order to respond to the technological changes in the production and distribution of information.

Yet again new technologies have altered the way of how (copyrighted) works are produced, copied, made obtainable and distributed. The emergence of global electronic networks and the increased availability of digitalized intellectual property confront existing copyright with a variety of questions and challenges. Although the combination of several types of works within one larger work or on one data carrier, and the digital format (although this may be a recent development it has been the object of detailed legal scrutiny), as well as networking (telephone and cable networks have been in use for a long time, although they do not permit interactivity) are nothing really new, the circumstance that recent technologies allow the presentation and storage of text, sound and visual information in digital form indeed is a novel fact. Like that the entire information can be generated, altered and used by and on one and the same device, irrespective of whether it is provided online or offline.

Asymmetric or Public-Key-Cryptosystems

Here the keys for encryption and decryption differ. There needs to exist a private key, which is only known to the individual, and a public key, which is published. Every person has her or his own private key that is never published. It is used for decrypting only. Mathematically the different keys are linked to each other, still it is nearly impossible to derive the private key from the public one.
For sending a message to someone, one has to look up the other's public key and encrypt the message with it. The keyholder will use his/her private key to decrypt it. While everybody can send a message with the public key, the private key absolutely has to stay secret - and probably will.

"The best system is to use a simple, well understood algorithm which relies on the security of a key rather than the algorithm itself. This means if anybody steals a key, you could just roll another and they have to start all over." (Andrew Carol)

very famous examples for public-key systems are:

· RSA:
The RSA is probably one of the most popular public-key cryptosystems. With the help of RSA, messages can be encrypted, but also digital signatures are provided.
The mathematics behind are supposedly quite easy to understand (see: http://world.std.com/~franl/crypto/rsa-guts.html.

· PGP:
PGP is a public key encryption program. Most of all it is used for e-mail encryption.
It is supposed to be quite safe - until now.

· PGPi is simply the international variation of PGP.

All of those tools, like hash functions, too, can help to enhance security and prevent crime.
They can theoretically, but sometimes they do not, as the example of the published credit card key of France in March 2000 showed.

Still, cryptography can help privacy.
On the other hand cryptography is only one element to assure safe transport of data. It is especially the persons using it who have to pay attention. A key that is told to others or a lost cryptographic key are the end of secrecy.
