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.

Method of detecting authorised biometric information sensor

A transducer is provided with an integral smart card reader. For security applications the transducer is a biometric information input device. The device provides co-operative operation of the smart card and the transducer to provide user specific processing of biometric information provided by the user. Because of the integral smart card reader, tampering and monitoring of security operations is prevented.
