In the present paper we try to introduce some new fuzzy based simulated by analyzing the finger prints images of various age group, through the images of fingerprints we can get the production of human behavior. The Fuzzy logic plays very important role and used as a tool for prediction of some uncertain information and disease too. Throughout this paper we propose the utilization of extended fuzzy rule for more flexible description of knowledge and consideration of uncertainty and lack of confidence in processing the image of finger prints.
