Resumen
The article reports that the latest research indicates using a combination of biometric avenues for human identification is more effective, and far more challenging. While biometric systems have their limitations they have an edge over traditional security methods in that they cannot be easily stolen or shared. Besides bolstering security, biometric systems also enhance user convenience by alleviating the need to design and remember passwords. Moreover, biometrics is one of the few techniques that can be used for negative recognition where the system determines. Biometric systems can operate in one of two modes--the identification mode, in which the identify of an unknown user is determined, and the idenfication mode, in which a claimed identity is either genuine user or rejected, an impostor. Biometric systems are being deployed in various applications including computer logins, ATMs, grocery stores, airport kiosks, and driver's licenses. The successful installation of biometric systems in these applications does not imply that biometrics is a solved problem.
