Media systems (especially broadcasting) can be classified in two different types:
Public Media Systems: Government control over broadcasting through ownership, regulation, and partial funding of public broadcasting services.
Private Media System: Ownership and control lies in the hands of private companies and shareholders.
Both systems can exist in various forms, according to the degree of control by governments and private companies, with mixed systems (public and private) as the third main kind.
Whereas public media systems are usually at least partially funded by governments, private broadcasting solely relies on advertising revenue. Still also public media systems cannot exclude advertising as a source of revenue. Therefore both types are to a certain degree dependent on money coming in by advertisers.
And this implies consequences on the content provided by the media. As the attraction of advertisers becomes critically important, interests of the advertising industry frequently play a dominant role concerning the structure of content and the creation of environments favorable for advertising goods and services within the media becomes more and more common.

In palm recognition a 3-dimensional image of the hand is collected and compared to the stored sample. Palm recognition devices are cumbersome artefacts (unlike fingerprint and iris recognition devices) but can absorb perform a great amount of identification acts in a short time. They are therefore preferably installed in situations where a large number of people is identified, as in airports.

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.

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

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.

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

The U.S.-Army School of Americas (= SOA) is based in Fort Benning (Georgia); it trains Latin American and U.S. soldiers in the working-field of counter-insurgency. Some of the nearly 60.000 SOA-Graduates have been responsible for many of the worst human rights abuses and crimes in Latin America. The list of famous dictators and murderers who went through the education of that institution is tremendous. In 1996 the U.S.-Government that always tried to deny the tasks of SOA, had to admit its work - but never closed it.
