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.

Multi modal biometrics are an example of preventive security applications in most industries such as government; where every single operation is a matter of life or death.
