Biometric software security systems enhance security by linking a unique physical attribute of a user to the data that they are allowed to access. The user provides their fingerprint (or other biometric) to the system, which is then authenticated against a stored template.

Biometric Middleware enables various biometric technologies and allows match / no-match decisions made by core technologies to provide authentication to various applications. It is similar to the concept of middleware in systems, integrates applications and resources. Flexible middleware is solutions adapted for applications.

Biometrics add an additional factor of authentication and are therefore a significant improvement in computer security. The most common biometric security systems use fingerprints, but these systems can also use iris and retinal scans, hand geometry, and facial recognition technology.
