This chapter deals with the holistic development of a biometric system based on acoustic ear recognition. Its main purpose is to map and investigate the many aspects within acoustic ear recognition, and based on the most influential ones, make attempts on deducing well performing recognition systems. Fifty subjects have participated in experiments collecting biometric samples. The measuring device composed of a pair of headphones with an integrated microphone as sensor. Several methods have been utilized for feature extraction, including principal component analysis, and various types of distance metrics and classifiers have been employed.
