Hiding+Information

There are many reasons why information is kept hidden such as it could be very valuable or personal to a person or even a county. Personnel in defence industries have to undear go rigourous back ground checks to see if they can be trusted with such information. Most senstive infomation these days is stored electronically and encrypted so non authorised personal accessing the system would not be able to access the information or would find it really hard. One of the first ways this was done was with the German Enigma machine that was used in WWII. The Enigma machine was used as a way for German forces to communicate with each other without the messages being understood if they were intercepted by the Allies. Unfortunately for the Germans a Enigma machine had been captured by British forces and the code was cracked by Turrin and German messages could then be understood by the Allies. Another reason for hiding information would be to make it easier for the user of a system to use the system. e.g. Windows hides the operationg system with a GUI and because it is hidden well a user of Windows may find it easy to use an Apple Mac computer. The same can be said for a car if you are driving a car you do not need to undersatnd how the internal combustion engine works to drive the car.
