Password detection via imagined wrist movement in BCI

It may be considered a cliche to say that brain is an electrochemical organ; researchers have speculated that a fully functioning brain can generate as much as 10 watts of electrical power. We can actually see these electrical changes in the form of brain waves as shown in an EEG (electroencephalogram). There are four categories of these brainwaves, ranging from the most activity (beta waves) to the least activity (delta waves). The purpose of the paper is to pragmatically assimilate the concept of brain emitting electrical power to perform basic task of password recognition when user ¿imagines¿ a hand movement. Such a system could allow a severely physically handicapped person to communicate with his computing surroundings securely. Here the distinction must be made between physically and mentally handicapped. A physically disabled person who has no control over his motor responses but does have control of his thoughts could use the system effectively.
