REGISTERING DEVICE, CHECKING DEVICE, PROGRAM, AND DATA STRUCTURE

摘要

A registering device having an improved authentication accuracy, a checking device, a program, and a data structure of identification data with an improved reliability are proposed. By using the end points and branch points of blood vessel lines shown in an image as references, the blood vessel lines are divided into partial lines. From each partial line, parameters indicating the shape of each partial line are extracted. Data including the end points and parameters of the partial lines and used for identifying an organism is created.
