1. Biometric Applications In recent years there have been heightened concerns about security due to the advancements of networking, communications, and mobility. This has led to the increase in biometrics in different applications for authentication and identification. The applications can be divided into 3 main groups Forensics, Government and Commercial (Jain, Flynn & Ross, 2008). 1.1 Forensics The use of biometrics in forensics has been used for a long time.

Nowadays as computer technology has become more available. Large Automated Fingerprint Identification Systems (AFIS) are used to match unknown fingerprints against a database.

This can be achieved by physical evidence.
