根据m序列的原理，用于产生任意位的小m序列。(According to the principle of m sequences, used to generate random bit sequence of the small m.)

Algorithm of the decision of the differential equation a method of final elements

it much easier to vary the parameters and see the results, but the underlying mathematical principles are unchanged. It shows that using polynomials of even modest degree to predict the future by extrapolating data is a risky business.

A biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual. Iris recognition is a part of the biometric identification methodologies which also include facial, fingerprint, palm and many other biological traits. They all offer new solutions for person identification, authentication and security. Currently users have to carry security badges or know certain pin/pass codes in order to get into secure zones or to log into a computer. In this paper we propose an algorithm for iris recognition, which can be applied in real time with standard webcam and with good matching result.
