The popularization of U disk makes virus from U disk spread fast.In order to protect the safety of information system,the authors designed a U disk virus isolator with three functions,firstly isolating Autorun virus from U disk,secondly preventing the PC's data from stealing by U disk,and thirdly preventing the PC's virus from spreading to U disk.The isolator can quickly capture all the data between the U disk and the PC,then the Micro Controller Unit(MCU) of the isolator analyzed,filtered and audited the data transport between U disk and computer to implement those three functions described above.Through actual measuring,it is found that this design can implement those three functions successfully.
