Even with the best techniques it is impossible to invent a cryptographic system that is absolutely safe/unbreakable. To decipher a text means to go through many, sometimes nearly - but never really - endless attempts. For the computers of today it might take hundreds of years or even more to go through all possibilities of codes, but still, finally the code stays breakable. The much faster quantum computers will proof that one day.
Therefore the decision to elect a certain method of enciphering finally is a matter of trust.
For the average user of computers it is rather difficult to understand or even realize the dangers and/or the technological background of electronic transmission of data. For the majority thinking about one's own necessities for encryption first of all means to trust others, the specialists, to rely on the information they provide.
The websites explaining the problems behind (and also the articles and books concerning the topic) are written by experts of course as well, very often in their typical scientific language, merely understandable for laymen. The introductions and other superficial elements of those articles can be understood, whereas the real background appears as untouchable spheres of knowledge.
The fact that dangers are hard to see through and the need for security measures appears as something most people know from media reports, leads directly to the problem of an underdeveloped democracy in the field of cryptography. Obviously the connection between cryptography and democracy is rather invisible for many people. Those mentioned media reports often specialize in talking about the work computer hackers do (sometimes being presented as criminals, sometimes as heroes) and the danger to lose control over the money drawn away from one's bank account, if someone steals the credit card number or other important financial data. The term "security", surely connected to those issues, is a completely different one from the one that is connected to privacy.
It is especially the latter that touches the main elements of democracy.

The most recent multilateral agreement on copyright is the 1996 WIPO Copyright Treaty. Among other things it provides that computer programs are protected as literary works and also introduces the protection of databases, which "... by reason of the selection or arrangement of their content constitute intellectual creations."

This process works even better on the Internet because of the latter's interactive nature. "The Internet is a dream to direct marketers", said Wil Lansing, CEO of the American retailer
Many web sites also are equipped with
One frequent way of obtaining such personal information of a user is by offering free web mail accounts offered by a great many companies, internet providers and web portals (e.g.
However, the intention of collecting users personal data and create consumer profiles based on online behaviour can also take on more creative and playful forms. One such example is
The particular way in which sites such as sixdegrees.com and others are structured mean that not only to users provide initial information about them, but also that this information is constantly updated and therefore becomes even more valuable. Consequently, many free online services or web mail providers cancel a user's account if it has not been uses for some time.
There are also other online services which offer free services in return for personal information which is then used for marketing purposes, e.g. Yahoo's
A further way of collecting consumer data that has recently become popular is by offering free PCs. Users are provided with a PC for free or for very little money, and in return commit themselves to using certain services rather than others (e.g. a particular internet provider), providing information about themselves, and agree to have their online behaviour monitored by the company providing the PC, so that accurate user profiles can be compiled. For example, the
