The Common Biometric Exchange File Format (CBEFF) is a biometric exchange file format.
With the CBEFF standard, systems can identify biometric systems, communicate with them and exchange data. The data for the exchange of biometric information between different system components, can be stored in a file. The CBEFF standard supports the exchange of biometric data between systems and thus the interoperability of biometric application programs. It serves technological improvements and ensures the compatibility of new applications.
