In a highly developed information society, personal identification for security measures has been highly demanded in a wide variety of usage. Authors propose to use auricles for the personal identification using human body characteristics in the next generation. In this paper we describe a method of feature extraction by the morphological operations relative to the square structuring elements for the purpose to roughly obtain shape feature of the auricle. This method leads to no errors of spectrum extraction and can extract feature points of the auricle based on the spectra. We also describe the examination of changes of the identical person's images with time under constant conditions of lighting and camera parameters.
