We apply a novel methodology, based on statecharts, to the design of large scale asynchronous systems. The design is specified at multiple levels, simulated, animated, and compiled into synthesizable VHDL code by using the ExpressV-HDL CAD tool . We add a validation sub-system to check correct operation. ExpressV-HDL is originally synchronous, but we employ(More)
Today almost all organizations in the world are networkcentric paradigm and to safeguard the data in a world where technology is advancing, systems are changing rapidly and information flows freely requires efficient secure channel at the endpoint.

The noise is one kind of feature which disturbs the real finger print pattern and makes the identification process is not efficient. Therefore we need to eliminate the noise, and recover the original finger print from noises. In order to recover the original finger(More)
The general encryption mechanism involves conversion of plain text into cipher text and decryption as vice versa, as well as multimedia(such as images, video, etc.,) the momentous aspect over here is that the converted cipher text always produces greater size than the original plain text. As there are innumerable number of internet users these days, more(More)
