Authenticating apparatus that authenticates operators
Provided is an authenticating apparatus that, in the case where authentication is performed repeatedly for the same operator, is capable of performing authentication without the operator having to consciously input unique information from the second time on. The weight scale measures the weight of an operator. The weight-registering unit, when an operator is authenticated as a user registered in an authentication list, registers the measured weight measured by the weight scale in the authentication list as a registered weight of the user. The user-selection-receiving unit receives a selection of a user. The weight-comparing unit authenticates an operator as a user registered in the authentication list by determining whether or not the registered weight of a user, of which a selection is received by the user-selection-receiving unit, is registered in the authentication list, and comparing the measured weight and the registered weight.
1. An authenticating apparatus that authenticates an operator as a user registered in an authentication list by receiving input from an operator of a candidate of unique information that does not change over time, and comparing the input with unique information registered in the authentication list and correlated with the user; the authenticating apparatus comprising:
a weight scale that measures a weight of an operator for registration and measures a weight of an operator for authentication;
a weight-registering unit that, when an operator is authenticated as the user registered in the authentication list, registers the weight measured for registration in the authentication list as a registered weight of the user;
a user-selection-receiving unit that receives a selection of a user registered in the authentication list;
a weight-comparing unit that authenticates an operator as a user registered in the authentication list by determining whether or not the registered weight of the user of which the selection is received by the user-selection-receiving unit is registered in the authentication list, and when the registered weight of the user of which the selection is received by the user-selection-receiving unit is registered in the authentication list, compares the weight measured for authentication and the registered weight of the user of which the selection is received by the user-selection-receiving unit; and
a display that provides a user-selection screen from which the selection is made, wherein the user-selection screen displays a plurality of user-selection buttons each corresponding to a respective user, and wherein the plurality of user-selection buttons are displayed differently for users for which weight is registered relative to users for which weight is not registered.
2. The authenticating apparatus according to claim 1 , wherein
the weight-comparing unit authenticates an operator as a user registered in the authentication list when a variation amount between the registered weight of the user of which the selection is received by the user-selection-receiving unit and the weight measured for authentication is less than a specified threshold value.
3. The authenticating apparatus according to claim 1 , wherein
the weight-registering unit registers a time at which the weight measured for registration is measured in the authentication list as a registration time; and
the weight-comparing unit compares the weight measured for authentication and the registered weight of the user of which the selection is received by the user-selection-receiving unit when a time elapsed from the registration time of the user for which a selection is received until the current time is less than a specified threshold time.
4. The authenticating apparatus according to claim 1 , wherein
the weight-registering unit deletes the registered weights registered in the authentication list at a specified timing.
