On use of biometrics in forensics: Gait and ear

We describe how gait and ear biometrics could be deployed for use in forensic identification. Biometrics has advanced considerably in recent years, largely by increase in computational power. This has been accompanied by developments in, and proliferation of, surveillance technology. To prevent identification, subjects use evasion, disguise or concealment. The human gait is a candidate for identification since other mechanisms can be completely concealed and only the gait might be perceivable. The advantage of use a human ear is its permanence with increase in age. As such, not only are biometrics ripe for deployment for forensic use, but also ears and gait offer distinct advantages over other biometric modalities.
