Attempts to dictate their rules to the media has become a common practice among marketers and the advertising industry. Similar as in the
According to a memo published by the New York Post, Coca-Cola demands a free ad from any publication that publishes a Coke ad adjacent to stories on religion, politics, disease, sex, food, drugs, environmental issues, health, or stories that employ vulgar language. "Inappropriate editorial matter" will result in the publisher being liable for a "full make good," said the memo by Coke advertising agency

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:
· 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.

Double bind messages are extremely effective.
For example in Nicaragua the
By the end of the 1980s the USA even paid Nicaraguans for voting other parties than the Sandinistas.
El Salvador was a similar case. Again the guerrilla got demonized. The difference was the involvement of the Catholic Church, which was highly fought against by the ruling parties of El Salvador - and those again were financially and organizationally supported by the USA. The elections in the 1980s were more or less paid by the USA.
U.S.-politicians were afraid El Salvador could end up being a second Cuba or Nicaragua. Every means was correct to fight this tendency, no matter what it cost.
On the 21st of September 1996, the

TCP and IP are the two most important protocols and communication standards. TCP provides reliable message-transmission service; IP is the key protocol for specifying how packets are routed around the Internet.

Founded in 1985, America Online is the world's biggest Internet service provider serving almost every second user. Additionally, America Online operates CompuServe, the Netscape Netcenter and several AOL.com portals. As the owner of Netscape, Inc. America Online plays also an important role in the Web browser market. In January 2000 America Online merged with Time Warner, the worlds leading media conglomerate, in a US$ 243,3 billion deal, making America Online the senior partner with 55 percent in the new company.
CNN is a U.S.-TV-enterprise, probably the world's most famous one. Its name has become the symbol for the mass-media, but also the symbol of a power that can decide which news are important for the world and which are not worth talking about. Every message that is published on CNN goes around the world. The Gulf War has been the best example for this until now, when a CNN-reporter was the one person to do the countdown to a war. The moments when he stood on the roof of a hotel in Baghdad and green flashes surrounded him, went around the world.
Pine Gap, run by the CIA, is near Alice Springs in central Australia and mostly an underground facility. Pine Gap was mainly established to serve as the groundstation and downlink for reconnaissance satellites like the RHYOLITE and ORION system. The facility consists of more than 7 large antennas in randomes. In Pine Gap's Signals Processing Office transmitted signals are received and transformed for further analysis.There is a no fly zone 4km around PG, and local land holders have agreed not to allow "visitors" access to there properties. It is said that Pine Gap employs nearly 1000 people, mainly from the CIA and the U.S. National Reconnaissance Office (NRO).
