“The first condition of progress is the removal of censorship” – George Bernard Shaw
Somebody out there thinks by blocking the blogs he has effectively crippled the terrorist. The point is he need to block the access to net and not just the blogs alone, since there are ample amount of collaboration tools out there like mails, writepads, newsgroups etc.
Long before people were comfortable with cryptography the secret messages were exchanged by indigenous idea. The art of hiding information is known as steganography. Here are few examples on how to hide information.
Throughout history, people have hidden information by a multitude of methods and variations. For example, ancient Greeks wrote text on wax-covered tablets. To pass a hidden message, a person would scrape wax off a tablet, write a message on the underlying wood and cover the tablet with wax to make it appear blank and unused. Another ingenious method was to shave the head of messenger and tattoo a message or image on the messenger’s head. After the hair grew back, the message would be undetected until the head was shaven again. Yet another method involved hard-boiled eggs, by making an ink from mixture of one ounce of alum and a pint of vinegar and then using it to write on the shell. The solution penetrated the porous shell and leaves the message on the surface of the hardened egg albumen which can be read only when shell is removed.
All the above methods are not for the real men. The real men from China used the following method. Chinese wrote the message on fine silk which was scrunched into tiny ball of wax. This was swallowed and later delivered to the concerned person across the geographical border.
So the wise men should also ban people from answering the nature’s call!
