Personal identification system (Assignee -- Identix, Inc.) November 21, 2002 6:09pm Abstract: A portable, hand-held personal identification device for providing secure access to a host facility includes a biometric sensor system capable of sensing a biometric trait of a user that is unique to the user and providing a biometric signal indicative of the sensed biometric trait. A processing unit responsive to the biometric signal is adapted to compare the biometric signal with stored biometric data representative of the biometric trait of an enrolled person that is unique to the enrolled person, and to provide a verification signal only if the biometric signal corresponds sufficiently to the biometric data to verify that the user is the enrolled person. The verification signal includes information indicative of the enrolled person or the device. A communication unit, including a transmitting circuit, is adapted to transmit the verification signal to a host system. Advertisement: Explore Within This Space Ex Claim Text: A method of providing secure access to a host facility, comprising: registering one or more persons with the host facility, including storing a unique ID code and a public encryption key for each registered person; receiving a first transmission comprising a first user signal at the host facility; generating and then transmitting a random number signal only if the first user signal represents one of the stored ID codes; receiving a second transmission comprising a second user signal at the host facility; decrypting the second user signal with the public encryption key associated with the registered person who is also associated with the stored ID code represented by the first user signal; and providing access to the host facility only if the decrypted second user signal represents the random number.
