Evolving mission needs coupled with advances in technology, have necessitated a new look at biometric priorities. Two or more biometrics modalities are combined in order to
- Optimise the accuracy rate which remarkably diminishes the failure rate due to the mixture of biometric applications.
- Differentiate the security levels that are allocated based on the particular security requirements depending on which area requires additional biometric identification/verification or authentication.
- Reduce the enrollment fail in large populations
The fusion methodology in multi-modal deployments alters depending on the security needs as cascaded multi modal applications or sequential ones.
