17th century Cardinal Richelieu invents an encryption-tool called grille, a card with holes for writing messages on paper into the holes of those cards. Afterwards he removes the cards and fills in the blanks, so the message looks like an ordinary letter. The recipient needs to own the same card
- Bishop John Wilkins invents a cryptologic system looking like music notes. In a book he describes several forms of steganographic systems like secrets inks, but also the string cipher. He mentions the so-called Pig Latin, a spoken way of encryption that was already used by the ancient Indians
- the English scientist, magician and astrologer
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.
1671 Leibniz invents a calculating machine that uses the binary scale which we still use today, more advanced of course, called the ASCII code
18th century this is the time of the Black Chambers of espionage in Europe, Vienna having one of the most effective ones, called the "Geheime Kabinettskanzlei", headed by Baron Ignaz von Koch. Its task is to read through international diplomatic mail, copy letters and return them to the post-office the same morning. Supposedly about 100 letters are dealt with each day.

1799 the Rosetta Stone is found and makes it possible to decipher the Egyptian Hieroglyphs
1832 or 1838 Sam Morse develops the Morse Code, which actually is no code but an enciphered alphabet of short and long sounds. The first Morse code-message is sent by telegraph in 1844.

1844 the invention of the telegraph changes cryptography very much, as codes are absolutely necessary by then
1854 the Playfair cipher is invented by Sir Charles Wheatstone
1859 for the first time a tomographic cipher gets described
1861 Friedrich W. Kasiski does a cryptoanalysis of the Vigenère ciphers, which had been supposed to be uncrackable for ages
1891 Major Etienne Bazeries creates a new version of the wheel cipher, which is rejected by the French Army
1895 the invention of the radio changes cryptography-tasks again and makes them even more important

Each definition of the Internet is a simplified statement and runs the risk of being outdated within a short time. What is usually referred to as the Internet is a network of thousands of computer networks (so called autonomous systems) run by governmental authorities, companies, and universities, etc. Generally speaking, every time a user connects to a computer networks, a new Internet is created. Technically speaking, the Internet is a
What constitutes the Internet is constantly changing. Certainly the state of the future Net will be different to the present one. Some years ago the Internet could still be described as a network of computer networks using a common communication protocol, the so-called
Also, the Internet is not solely constituted by computers connected to other computers, because there are also point-of-sale terminals, cameras, robots, telescopes, cellular phones, TV sets and and an assortment of other hardware components that are connected to the Internet.
At the core of the Internet are so-called
Since these networks are often privately owned, any description of the Internet as a public network is not an accurate. It is easier to say what the Internet is not than to say what it is. On 24 October, 1995 the U.S.
What is generally and in a simplyfiying manner called the Internet, may be better referred to as the Matrix, a term introduced by science fiction writer
Strictly speaking, the Matrix is not a medium; it is a platform for resources: for media and services. The Matrix is mainly a very powerful means for making information easily accessible worldwide, for sending and receiving messages, videos, texts and audio files, for transferring funds and trading securities, for sharing resources, for collecting weather condition data, for

Never before propaganda had been as important as in the 2nd World War. From now on education was one more field of propaganda: its purpose was to teach how to think, while pure propaganda was supposed to show what to think.
Every nation founded at least one ministry of propaganda - of course without calling it that way. For example the British called it the Ministry of Information (= MOI), the U.S. distinguished between the Office of Strategic Services (= OSS) and the Office of War Information (= OWI), the Germans created a Ministry of Propaganda and Public Enlightenment (= RMVP) and the Japanese called their disinformation and propaganda campaign the "Thought War".
British censorship was so strict that the text of an ordinary propaganda leaflet, that had been dropped from planes several million times, was not given to a journalist who asked for it.
Atrocity stories were no longer used the same way as in the 1st World War. Instead,
German war propaganda had started long before the war. In the middle of the 1930s
Some of the pictures of fear, hatred and intolerance still exist in people's heads. Considering this propaganda did a good job, unfortunately it was the anti-national-socialist propaganda that failed at that time.

As a
A bottom-up
The retouch is the simplest way to change a picture. Small corrections can be made through this way.
A well-known example is the correction of a picture from a Bill Clinton-visit in Germany. In the background of the photograph stood some people, holding a sign with critical comments. In some newspapers the picture was printed like this, in others a retouch had erased the sign.
Another example happened in Austria in 1999:
The right wing party FPÖ had a poster for the Parliamentarian elections which said: 1999 reasons to vote for Haider. Others answered by producing a retouch saying: 1938 reasons to not vote for Haider (pointing to the year 1939, when the vast majority of the Austrians voted for the "Anschluss" to Germany).

Educator who developed a system of printing and writing that is extensively used by the blind and that was named for him. Himself blind Braille became interested in a system of writing, exhibited at the school by Charles Barbier, in which a message coded in dots was embossed on cardboard. When he was 15, he worked out an adaptation, written with a simple instrument, that met the needs of the sightless. He later took this system, which consists of a six-dot code in various combinations, and adapted it to musical notation. He published treatises on his type system in 1829 and 1837.
