Definitions

Biometric Data Interchange Formats define an encoding scheme according to which biometric data is stored in a biometric reference. In most cases the stored data will be used for future comparisons with biometric data stemming from the same or different subject. Encoded data should not only contain a digital representation of a biometric characteristic (e.g., fingerprint image, face image) but also relevant metadata that impacted the capturing process (e.g., resolution of fingerprint sensor). Standardized Data Interchange Formats are a fundamental precondition to implement open systems where biometric data can be processed with components of different suppliers.

Introduction

Biometric systems are characterized by the fact that essential functional components are usually dislocated. While the enrolment may take place as part
