1. An information processing system comprising:
a memory storing instructions; and
a processor configured to execute the instructions to:
acquire a feature point extracted from a biometric image including a pattern of a living body;
set a first reference point and a second reference point corresponding to different positions of the biometric image;
calculate first position information indicating a relative position of the first reference point with respect to the feature point and second position information indicating a relative position of the second reference point with respect to the feature point;
select one of the first position information and the second position information, wherein the first position information is selected when a distance from the feature point to the first reference point is less than a distance from the feature point to the second reference point, and the second position information is selected when the distance from the feature point to the second reference point is less than the distance from the feature point to the first reference point; and
perform biometric matching between a target person from which the biometric image is acquired and a registered person registered in advance, based on the selected one of the first position information and the second position information.
