1. An information providing device comprising:
at least one memory storing a set of instructions; and
at least one processor configured to execute the set of instructions to:
receive a face image;
perform unsuitable-data determination of determining whether iris data extracted from the face image is suitable for iris authentication;
when the iris data is determined to be unsuitable,
perform an unsuitability-level determination of determining an unsuitability-level of the face image for the iris authentication using the iris data extracted from the face image, the unsuitability-level indicated by an amount of an obstacle that covers an iris, and
repeat reception of a new face image, the unsuitable-data determination of the new face image and the unsuitability-level determination of the new face image;
when the unsuitability-level is determined to be unchanged, determine a person in the face image is unsuitable for iris data acquisition by using the unsuitability-level of the face image and the unsuitability-level of the new face image; and
output information based on the determination that the person is unsuitable for the iris data acquisition when the person is determined to be unsuitable for the iris data acquisition.
