Person identification is one of the most important problems fo highly advanced present computer system for its security. It is absolutely necessary to keep off trespassers at the computer room. the materials room. etc.. Fingerprint is usually used for gate security because it has the highest reliability for personal identification. but it has fear to infringe on privacy. In this paper, a new gate security method using the length of joints of hand fingers is proposed and the result of fundamental experiment using 50 person's data is shown. Since these features have not so high reliability as fingerprint. it has little faer to infringe on privacy. This method consists of two ways. that is. the first is identification by similarity degree, second is identification by Euclid distance. From the result of the experiment. it can be said that the probability of keeping off the trespassers is 84.2 (%) when the proposed method is used for gate security. If the method is used together with an ID card and a password. very high reliability can be obtained.
