Biometrics is now the significant identification process for security system. The futureof biometrics is surely leads to a system because the acquisition process for biometricsis very simple. Ear biometrics has an important role on biometrics system. Because it isa passive biometrics system which means that the user does not have to take active partin the whole process. The most interesting human anatomical parts for such passive,physiological biometrics systems based on images acquired from cameras are face andear. This paper introduces to ear biometrics as a passive human identification systems.Using two different methods and comparison between them help anyone to find the bestear biometrics method. Geometrical method of feature extraction from human earimages in order to perform human identification is presented with the help of twodifferent edge detection algorithms.Keywords: Biometrics, ear identification, passive biometrics, geometrical method
