Apparatus and a method for preventing unauthorized use and a device with a function of preventing unauthorized use
First Claim
1. An apparatus for preventing unauthorized use, the apparatus comprising:
- an authentication unit that compares a characteristic included in a user'"'"'s input into a device with a registered characteristic of a person to determine as an authentication result a likelihood of the user'"'"'s being the person;
a memory for storing a value that is determined based on an authentication result by the authentication unit and indicates a likelihood of being the person;
a first controller that controls a value indicating a likelihood of being the person which is to be stored in the memory, based on an authentication result determined by the authentication unit from a user'"'"'s input including input other than input done in response to an input request for authentication, and based on a passage of time; and
a second controller that, in response to an instruction to begin a process which requires authentication, refers to a value indicating a likelihood of being the person and stored in the memory and controls whether or not to permit execution of the process instructed to begin depending on whether or not the referred value is a certain threshold or more.

Abstract
A device comprises an authentication section that compares a characteristic included in a user'"'"'s input into an input section with a characteristic of a person registered in a comparison data memory so as to determine an authentication result. An authentication control section comprises a function to store a value indicating a likelihood of being the person, which is determined based on the above authentication result, and to control the value indicating a likelihood of being the person which is to be stored, based on the authentication result determined as above from a user'"'"'s input including input other than input done in response to an input request for authentication, and based on a passage of time; and a function to, in response to an instruction to begin a process which requires authentication, control whether or not to permit execution of the process depending on whether or not a stored value indicating a likelihood of being the person is a certain threshold or more. Unauthorized use of a device is prevented, while a trouble of being asked to make a special input for authentication is resolved when a process requiring authentication is executed.

16. A method for preventing unauthorized use in a device comprising an authentication module that compares a characteristic included in a user'"'"'s input into the device with a registered characteristic of a person to determine as an authentication result a likelihood of the user'"'"'s being the person, the method comprising:
-
determining an authentication result by the authentication module from a user'"'"'s input other than input done in response to an input request for authentication;
storing in a memory a value that is determined based on the authentication result and indicates a likelihood of being the person;
decreasing, as time passes, a value indicating a likelihood of being the person and stored in the memory;
referring to a value indicating a likelihood of being the person and stored in the memory in response to an instruction to begin a process which requires authentication; and
controlling whether or not to permit execution of the process instructed to begin depending on whether or not the referred value is a certain threshold or more. - View Dependent Claims (17, 18)

19. A program for preventing unauthorized use which is to be stored in a memory of a device comprising an authentication module that compares a characteristic included in a user'"'"'s input into the device with a registered characteristic of a person to determine as an authentication result a likelihood of the user'"'"'s being the person, wherein the program
makes the authentication module determine an authentication result from a user'"'"'s input other than input done in response to an input request for authentication; -
makes the memory store a value that is determined based on the authentication result and that indicates a likelihood of being the person;
decreases, as time passes, a value indicating a likelihood of being the person and stored in the memory;
refers to a value indicating a likelihood of being the person and stored in the memory in response to an instruction to begin a process which requires authentication; and
controls whether or not to permit execution of the process instructed to begin depending on whether or not the referred value is a certain threshold or more.

20. A device with a function of preventing unauthorized use, the device comprising:
-
an input unit that accepts a user'"'"'s input;
a process unit that executes an instructed process;
an authentication unit that compares a characteristic included in an input accepted by the input unit with a registered characteristic of a person to determine as an authentication result a likelihood of the user'"'"'s being the person;
a memory for storing a value that is determined based on an authentication result by the authentication unit and indicates a likelihood of being the person;
a first controller that controls a value indicating a likelihood of being the person which is to be stored in the memory, based on an authentication result determined by the authentication unit from a user'"'"'s input including input other than input done in response to an input request for authentication, and based on a passage of time; and
a second controller that, in response to an instruction to begin a process which requires authentication, refers to a value indicating a likelihood of being the person and stored in the memory and permits or refuses the process unit'"'"'s executing the process instructed to begin depending on whether or not the referred value is a certain threshold or more. - View Dependent Claims (21, 22)
