Securing information and operations in a smart card through biometrics

Many systems need portable media in which to store sensible data, such as smart cards. The information can be protected by the user with their personal identification number (PIN), or through biometrics. Unfortunately, there isn't a smart card that can verify the biometric template inside it, performing this task in the terminal. The author has developed algorithms and data structures needed to solve this problem. Therefore, he has created a smart card with user biometric authentication, based on an open platform smart card (in this case, a JavaCard). To achieve these results, different biometric techniques have been studied: speaker verification, hand geometry and iris recognition. Experimental results are given to show the viability of the prototype developed.
