A user-friendly interface for fingerprint recognition systems based on natural language processing

Biometric recognition systems represent a valid solution to the safety problem of internet accessibility, even if they do not always provide an environment easily comprehensible by users and operators with a mid-level of competence. This gap can be partially filled if, instead of using the conventional access routines to the authentication system, the user could simply write to the system through the interface and using high level sentences and requests be able to use its own natural language to reach the intended goal. On the other hand, biometrics features are widely used for recognition and identification all over the world, generating large databases. In this paper a user-friendly interface for the use and management of biometric recognition systems is proposed. The interface allows for a simpler and more natural access to the functionalities offered by biometric systems, increasing system usability. The interface allows for an intuitive parameterization of functions and procedures of system algorithms, for the optimized management of great databases by unspecialized operators. In addition, the interface addresses the fail-to-enrol issue, because the quality of the acquired fingerprint is computed at the acquisition time. © 2009 IEEE.
