Abstract
An identification system for identifying authorized personnel compares a streaked pattern of a fingerprint of an individual with selected fingerprint patterns stored in memory of all authorized personnel in order to determine if the individual is included among the authorized personnel. The streaked pattern is compared with the fingerprint patterns stored in memory on the basis of characteristics between a reference point of a fingerprint and its relationship to other selected points of the fingerprint.
