Following the communist revolutions of the 20th century all "means of production" became the property of the state as representative of "the masses". Private property ceased to exist. While moral rights of the creator were recognized and economic rights acknowledged with a one-time cash award, all subsequent rights reverted to the state.
With the transformation of many communist countries to a market system most of them have now introduced laws establishing markets in intellectual property rights. Still the high rate of piracy reflects a certain lack of legal tradition.

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.

Digital technologies are used to combine previously separated communication and media systems such as telephony, audiovisual technologies and computing to new services and technologies, thus forming extensions of existing communication systems and resulting in fundamentally new communication systems. This is what is meant by today's new buzzwords "multimedia" and "convergence".
Classical dichotomies as the one of computing and telephony and traditional categorizations no longer apply, because these new services no longer fit traditional categories.
Convergence and Regulatory Institutions
Digital technology permits the integration of telecommunications with computing and audiovisual technologies. New services that extend existing communication systems emerge. The convergence of communication and media systems corresponds to a convergence of corporations. Recently,

With the dissemination of their content commercial media are among other things also able to transport values and ideologies. Usually their programming reflects society's dominant social, political, ethical, cultural and economical values. A critical view of the prevalent ideologies often is sacrificed so as not to offend the existing political elites and corporate powers, but rather satisfy shareholders and advertisers.
With most of the worlds content produced by a few commercial media conglomerates, with the overwhelming majority of companies (in terms of revenue generation) concentrated in Europe, the U.S., Japan and Australia there is also a strong flow of content from the 'North-West' to the 'South-East'. Popular culture developed in the world's dominant commercial centers and Western values and ideologies are so disseminated into the most distant corners of the earth with far less coming back.

Traditional copyright and the practice of paying
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.

Providers of digital information might be confronted with copyright related problems when using some of the special features of hypertext media like
Framing
Frames are often used to help define, and navigate within, a content provider's website. Still, when they are used to present (copyrighted) third party material from other sites issues of passing off and misleading or deceptive conduct, as well as copyright infringement, immediately arise.
Hyperlinking
It is generally held that the mere creation of a hyperlink does not, of itself, infringe copyright as usually the words indicating a link or the displayed URL are unlikely to be considered a "work". Nevertheless if a link is clicked on the users browser will download a full copy of the material at the linked address creating a copy in the RAM of his computer courtesy of the address supplied by the party that published the link. Although it is widely agreed that the permission to download material over the link must be part of an implied license granted by the person who has made the material available on the web in the first place, the scope of this implied license is still the subject of debate. Another option that has been discussed is to consider linking
Furthermore hyperlinks, and other "information location tools", like online directories or search engines could cause their operators trouble if they refer or link users to a site that contains infringing material. In this case it is yet unclear whether providers can be held liable for infringement.

- the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes (usually certain types of educational copying are allowed)
- the nature of the copyrighted work (mostly originals made for commercial reasons are less protected than their purely artistic counterparts)
- the amount and substantiality of the portion used in relation to the copyrighted work as a whole
- the effect of the use upon the potential market for or value of the copyrighted work (as a general rule copying may be permitted if it is unlikely to cause economic harm to the original author)
Examples of activities that may be excused as fair use include: providing a quotation in a book review; distributing copies of a section of an article in class for educational purposes; and imitating a work for the purpose of parody or social commentary.

1605/1623 Sir Francis Bacon (= Francis Tudor = William Shakespeare?) writes several works containing ideas about cryptography. One of his most important advises is to use ciphers in such a way that no-one gets suspicious that the text could be enciphered. For this the steganogram was the best method, very often used in poems. The attempt to decipher Shakespeare's sonnets (in the 20th century) lead to the idea that his works had been written by Francis Bacon originally.

Born in Grand Chute, Wisconsin, Joe McCarthy graduated from Marquette in 1935. In 1939, he won election as a circuit court judge. During World War II, he enlisted in the Marines and served in the Pacific. In 1944, he campaigned for senator but lost in the Republican primary. In 1946, he ran for Wisconsin's other senate seat.
In a 1950 speech, McCarthy entered the public spotlight by claiming that communists had "infested" the State Department, dramatically waving a sheet of paper which purportedly contained the traitors' names. A special Senate committee investigated the charges and found them groundless. Unfazed, McCarthy used his position to wage a relentless anti-communist crusade, denouncing numerous public figures and holding a series of highly confrontational hearings, ruining the careers of many people.
He died at the age of 49 of complications related to alcoholism.
Oscar Flingal O'Flahertie Wills (1854-1900) is one of the best and most famous poets and novelists of England of his time. His satirical and amusing texts exposed the false moral of the Bourgeoisie publicly. Besides, his life as a dandy made him the leader of aesthetics in England, until he was sent to prison because of homosexuality. Afterwards he lived in Paris where he died lonely and nearly forgotten in a hotel in 1900. His poems, fairy tales, novels and dramas survived.
In November 1997, after the assassination of (above all Swiss) tourists in Egypt, the Swiss newspaper Blick showed a picture of the place where the attack had happened, with a tremendous pool of blood, to emphasize the cruelty of the Muslim terrorists. In other newspapers the same picture could be seen - with a pool of water, like in the original. Of course the manipulated coloured version of the Blick fit better into the mind of the shocked Swiss population. The question about death penalty arose quickly ....

Claude Chappe built a fixed optical network between Paris and Lille. Covering a distance of about 240kms, it consisted of fifteen towers with semaphores.
Because this communication system was destined to practical military use, the transmitted messages were encoded. The messages were kept such secretly, even those who transmit them from tower to tower did not capture their meaning, they just transmitted codes they did not understand. Depending on weather conditions, messages could be sent at a speed of 2880 kms/hr at best.
Forerunners of Chappe's optical network are the
For more information on early communication networks see
This book gives a fascinating glimpse of the many documented attempts throughout history to develop effective means for long distance communications. Large-scale communication networks are not a twentieth-century phenomenon. The oldest attempts date back to millennia before Christ and include ingenious uses of homing pigeons, mirrors, flags, torches, and beacons. The first true nationwide data networks, however, were being built almost two hundred years ago. At the turn of the 18th century, well before the electromagnetic telegraph was invented, many countries in Europe already had fully operational data communications systems with altogether close to one thousand network stations. The book shows how the so-called information revolution started in 1794, with the design and construction of the first true telegraph network in France, Chappe's fixed optical network.
