Identification, verification and templates

In this chapter we shall examine the distinction between identification and verification, the management of biometric templates and the impact this has on systems design, and we shall also take a look at the question of established performance criteria and how this relates to actual system performance. These are all issues which are important to understand if we are contemplating the use of biometrics. Furthermore, they are factors which should be considered in advance of any detailed planning with respect to biometric systems design.
