This paper present a new practical authentication system which is depend on one of the biometrics features Hand Geometry features. the proposed system Captures human hand image to extract 50 features then use these features in creating for database system authenticate users stage and recognition stage. The paper present a complete and clear study of the basic fundamentals open set principle and shown the effect of population size on the recognition rate. Good results was obtain that is more than 91% in this application. MATLAB7.9.0 (2009b) programming language has been used to execute the paper algorithms, because its facilities in processing digital images.
