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;
determine whether a person in the face image is unsuitable for iris data acquisition based on the face image by:
attempting acquisition of the iris data from the face image;
performing determination including determining whether the iris data is acquired and determining whether quality of the iris data acquired is sufficient to be used for authentication; and
determining whether the person is unsuitable for the iris data acquisition when the iris data is not acquired or when quality of the acquired iris data is determined to be not sufficient to be used for authentication;
output information based on determining that the person is unsuitable for the iris data acquisition when the person is determined to be unsuitable for the iris data acquisition;
output a message to the person when the person is not determined to be unsuitable for the iris data acquisition;
attempt acquisition of iris data from a new face image when the new face image is input after the message is output, and perform the determination; and
determine that the person is unsuitable for the iris data acquisition when a count of times when the message is output to the person exceeds a threshold in a case where the iris data having quality sufficient to be used for authentication is not acquired even once from the person.
