Secure network and networked devices using biometrics

Abstract

A biometric data sample is taken and compared with stored biometric data. If the biometric data sample matches stored data, access to a secure data storage module is enabled. The secure data storage module contains data necessary for successful communication with a server, as detailed further below. Accordingly, a biometric data match enables sensitive data retrieval, and ultimately secure communication with another device. In a preferred embodiment, the Subscriber Identity Module (SIM) in a GSM phone provides stored biometric data and processing capabilities for the matching function within a cellular phone. By storing biometric data on the SIM (a type of smart card) and performing the biometric matching process on the SIM, the need to transmit or store biometric data in a way that leaves it available for retrieval or tampering is minimized.
