Reliable authorization and authentication are becoming necessary for many everyday applications such as boarding an aircraft, performing financial transaction, logging to a secure system etc. Identity verification becomes a challenging task when it has to be automated with high accuracy and with low probability of break-ins and low rates of false match. Moreover, person verification is not a new problem and society had created three traditional modes of designation: 1. Possessions: Physical possessions such as keys, passports and smart cards. 2. Knowledge: Pieces of information those are secret and known only to the right person such as PIN, passwords, user names etc. 3. Biometrics: Physiological and behavioral characteristics of individuals that distinguish one person from the others. These characteristics are different in each person.

VOIP业务仿真建模，使用间歇泊松过程模型，能够图形显示业务的突发特性。(VOIP business modeling and simulation, using the batch Poisson process model, which can burst characteristics of graphics operations.)

两靖rayleigh衰落信道仿真。This m-file uses successive iterations of data to create an animated = effect ％showing the results of passing an unmodulated carrier through a simple = two ％path Rayleigh fading channel. The following formula and diagram ％illustrates the m-file operation. The animation shows, input(blue) ％and the output(red), the the phase shifts, gains, and attenuations ％of the output sine wave or carrier.(Two Jing Rayleigh fading channel simulation.
