  • Method for biometric-based authentication in wireless communication for access control
    Patent number: 6819219
    Abstract: Smart cards systems that are utilized in biometric authentication are slow in processing and have the cards themselves have the added disadvantage of being misplaced or lost. Moreover, storing biometric data (on a database) over a network poses security issues that in extreme instances can be compromised. Significant security can be achieved if the biometric templates are stored locally in a portable device. A user can use the portable device to either transmit wirelessly the stored biometric for authentication purposes, or a user can locally measure a biometric using the portable device and match it against a biometric which is also stored locally (in the portable device).
