Abstract:
1. An authentication information registration method, the method comprising: calculating parallel translation and rotational transformation, so that based on predetermined configuration requirements for digital imaging means, a target to be authenticated is scanned by the digital imaging means a plurality of times to obtain digital data, a plurality of sets of digital data thus obtained are compared with each other, and locations at which mapping for the target to be authenticated is performed using the digital data are matched; employing the obtained parallel translation and rotational transformation to designate correlated locations of pixel arrays of the plurality of sets of digital data, and calculating an optical data difference for the correlated locations that are designated; calculating a physical size for a subject, with respect to a pixel size of digital data based on configuration requirements for the digital imaging means, employing the obtained physical size to calculate, as connection points, midpoints of physical positions of the subject that correspond to the center positions of pixels that are located at the corresponding positions, coupling the connection points in the descending order, by an arbitrary number of times, beginning with the largest optical data difference, and extracting connected lines as individual difference data; and registering the extracted connected lines at storage means.
