Biometric person identification is a common technological tool for identity verification and carries significant importance for national or international security. Fingerprint, palm print, face, iris, ear etc are some of the unique features in human being and are used for automate identity and authentication. Ear detection is a new class of relatively stable biometrics which is not affected by facial expressions, cosmetics, eye glasses and aging effects. It has been suggested by the researchers that the shape and features of ear are unique for each person and invariant with age. In this paper geometric based ear detection has been discussed, as simple geometric approach which is based on the concept of max line.
