Personal identification and verification using multimodal biometric data

Abstract

Several proposals have been formulated to combine cryptography and biometrics in order to secure data and to strengthen the personal authentication process, making the falsification of personal ID, like passports, more challenging. In this work we describe a system for personal identification and verification, based on the combination of multiple biometric readings and other user inputs. In such way authentication control can be performed and only allowed persons can access the resources which must be protected. The method consists of two main phases: enrollment and verification. In the first phase the data extracted from user inputs are processed by the proposed system and stored the in a innovative non-reversible form. In the second phase, the stored data are combined with the biometric readings and other user inputs in order to identify and verify the identity of the person. The system does not rely on network access or databases to perform the verification/authentication phase
