<p>The invention relates to user identify identifying anti-theft system and its identifying method. It includes CPU, peripheral device, the information carrier for specific user and relevant system software.The peripheral includes writing device for loading and renewing random code generated by CPU to the information carrier and reading device for transferring random code from the carrier to CPU. Accordingly, the system verifies sequence code of the user's identification the fixed check cipher and random code, then, generates new random code and renew the random code in the information carrier. When user identify is counterfeited and user information carrier is copied illegally, the random code will be renewed. It makes real legal user find out the abnormal and deal with it in time so that user identify isn't counterfeited for a long time.</p> |
