Different human ethnic races have different morphological characteristics and measurements of the external ear, which can be used in forensics to identify live or deceased people. Biometrics plays an important part in individualization. The most common types are fingerprints, palm prints, retina, and iris. The face is more easily used in surveillance scenarios where fingerprint and iris capture are not feasible. However, due to variations in emotion, lighting, and make-up, the face is not yet as precise and adaptable as expected. However, ear images can be acquired similarly to facial images and used in biometry. Different human ethnic races have different morphological characteristics and measurements of the external ear, which can be used in forensics to identify live or deceased people. Biometrics plays an important part in individualization. The main contribution of this work lies in the comparative examination of the uniqueness of morphological, ethnical, and biometric variations of both ears for individualization among the different sub-population of India and other ethnic groups of the world. The study shall help anthropological and forensic science agencies with the inclusion and exclusion of persons for identification based on ear variations.
