1. An image processing apparatus, comprising:
an image processing unit; and
a controller configured to:
receive biometric information for a user for a logon operation;
re-order user record entries in a table when a predetermined condition is satisfied, each record entry in the table including reference biometric information in association with user information, the re-ordering being based on user information stored in the user record entries; and
perform an authentication operation after the re-ordering of user record entries in the table, the authentication operation including comparing the received biometric information to reference biometric information in user record entries in the table, wherein
the user information in each user record entry includes last login information reflecting the last time and date of a logon operation for a user associated with the user record entry.
