Abstract
In the past, a contact imaging device was physically secured to prevent tampering. When used with network computer systems or communications systems, securing a contact imager is difficult. According to the invention, a method is proposed for securing a contact imaging device from tampering and for ensuring a contact imaging device is an authorised contact imaging device for use with a personal computer, a network application, or a communications application.
