Information System View of Biometric Analysis

Up till now, biometric techniques used for unique identification of person had not taken into account the local environmental factors corresponding to the system. The local environmental factors involve the hardware, software, people, finance, norms, rules procedures and policies etc. As the local environment is going to be complex and changing, the biometric technique is going to experience the uncertainties. Beyond shear accuracy, there are many other factors to consider when examining a biometric solution for an application, such as vulnerability to fraud, the degree of distinctiveness or uniqueness of the biometric, liveness, the long-term support required (database management, re-enrollment, template updating) and the error implications in the biometric system. The information systems view of biometric (BIS) analysis presented represents each stage of the system starting from person that is imposed to the system till the output or the match display, in its informational view. To start with, the user´s information regarding his/her ergonomics (anthropometrics data), working environment, liveness, culture, psychology etc. have equal importance along with technical factors involved in system design. The further stages that are cameras/sensors, other hardware, software involved all have such local environment and moreover these stages are interconnected with each other. Hence the system is now represented as loosely connected system
