Abstract: Natural immune systems protect animals from dangerous foreign pathog ens,including bacteria,viruses,parasites.Their role in the body is analogous to that of computer security systems in the computer. Based on the priciples of i mm unology the authors realize a computer immune system which can protect the da ta stored in the computer ,it also can response against the changing to the pro tect ing data and the infection of the viruses in time.
