Abstract

An imaging system is disclosed that performs authentication of a user. The system includes one or more manipulation detecting parts that detect one or more manipulations by the user related to an imaging process, one or more biometric information acquiring parts that acquire biometric information of the user when the manipulation detecting parts detect the manipulations by the user, and an authentication determining part that determines an authentication result of the authentication based on the biometric information acquired by the biometric information acquiring parts.

Claims

1. An imaging system that performs authentication of a user and that is configured to perform a copying operation and a scanning operation, the system comprising:

an operation input unit for the user to set conditions for at least one of the copying operation and the scanning operation;

an automatic document feeder unit;

a plurality of manipulation detecting parts including a first sensor that detects one or more manipulations by the user of the operation input unit to set the conditions for said at least one of the copying operation and the scanning operation, and a second sensor that detects a recording medium being placed in the automatic document feeder unit;

a plurality of biometric information acquiring parts that acquire biometric information of the user when the manipulation detecting parts detect the manipulations by the user, the biometric information acquiring parts include

a first camera disposed to capture a first facial image of the user at a first predetermined location relative to the operation input unit, when the first sensor detects the one or more manipulations by the user of the operation input unit, and

a second camera disposed to capture a second facial image of the user at a second predetermined location relative to the automatic document feeder unit, when the second sensor detects the recording medium placed in the automatic document feeder unit;

an authentication determining part that determines an authentication result of the authentication based on the biometric information acquired by the biometric information acquiring parts;

a biometric information storing part that stores pre-acquired biometric information; and

a matching part that compares and matches the biometric information acquired by the biometric information acquiring part with the pre-acquired biometric information stored in the biometric information storing part,

wherein the authentication determining part determines the authentication result based on one or more matching results obtained by the matching part,

wherein in a case that the authentication result determined by the authentication determining part corresponds to authentication success, the authentication result corresponding to authentication success becomes invalid after an imaging process that is related to the detected manipulations by the user is completed.

2. The imaging system as claimed in claim 1, wherein

a predetermined manipulation detecting part of the manipulation detecting parts and a predetermined biometric information acquiring part of the biometric information acquiring parts are grouped together, and the predetermined biometric information acquiring part acquires the biometric information when the predetermined manipulation detecting part detects the manipulations by the user.

3. The imaging system as claimed in claim 2, wherein

the predetermined manipulation detecting part and the predetermined biometric information acquiring part are arranged in a predetermined positional relationship.

4. The imaging system as claimed in claim 1, wherein

when at least one of a predetermined number of the matching results is obtained and at least another one of the predetermined number of the matching results is not obtained, the authentication determining part determines the authentication result based on the obtained matching results.

5. The imaging system as claimed in claim 1, wherein

authentication failure is determined by the authentication determining part when at least one of a predetermined number of the matching results is not obtained.

6. The imaging system as claimed in claim 1, wherein the authentication determining part performs authentication each time one of the copying operation and the scanning operation is set.

7. The imaging system as claimed in claim 1, wherein the authentication determining part determines successful authentication only when matching results are obtained for both of the first facial image of the user captured by the first camera and the second facial image of the user captured by the second camera.

8. The imaging system as claimed in claim 1, wherein when the authentication result corresponds to authentication success, the authentication result corresponding to authentication success becomes invalid after said at least one of the copying operation and the scanning operation is completed.

9. The imaging system as claimed in claim 1, wherein the user is prevented from performing the copying operation and the scanning operation when the authentication result corresponding to authentication success becomes invalid.

10. The imaging system as claimed in claim 1, wherein when the detected manipulations detected by the manipulation detecting parts correspond to the copying operation and the authentication result corresponds to authentication success, the authentication result corresponding to authentication success becomes invalid after the copying operation is completed.

11. The imaging system as claimed in claim 1, wherein when the detected manipulations detected by the manipulation detecting parts correspond to the scanning operation and the authentication result corresponds to authentication success, the authentication result corresponding to authentication success becomes invalid after the scanning operation is completed.

12. An imaging system that performs authentication of a user and that is configured to perform a copying operation and a scanning operation, the system comprising:

an imaging apparatus including

an operation input unit for the user to set conditions for at least one of the copying operation and the scanning operation;

an automatic document feeder unit;

a plurality of sensors including a first sensor that detects one or more manipulations by the user of the operation input unit to set the conditions for said at least one of the copying operation and the scanning operation, and a second sensor that detects a recording medium being placed in the automatic document feeder unit; and

a plurality of image capturing units that acquire biometric information of the user when the sensors detect the manipulations by the user, the image capturing units include

a first camera disposed to capture a first facial image of the user at a first predetermined location relative to the operation input unit, when the first sensor detects the one or more manipulations by the user of the operation input unit, and

a second camera disposed to capture a second facial image of the user at a second predetermined location relative to the automatic document feeder unit, when the second sensor detects the recording medium placed in the automatic document feeder unit; and

a server apparatus that is connected to the imaging apparatus and receives the biometric information from the imaging apparatus, the server apparatus including an authentication determining unit that determines an authentication result of the authentication based on the biometric information,

wherein in a case that the authentication result determined by the authentication determining part corresponds to authentication success, the authentication result corresponding to authentication success becomes invalid after an imaging process that is related to the detected manipulations by the user is completed.

13. An authentication method used in an imaging system that performs authentication of a user and that is configured to perform a copying operation and a scanning operation, the system including an automatic document feeder unit and an operation input unit for the user to set conditions for at least one of the copying operation and the scanning operation, the method comprising:

one or more manipulation detecting steps for detecting one or more manipulations by the user that are related to an imaging process, the manipulation detecting steps including

detecting, by a first sensor, one or more manipulations by the user of the operation input unit to set the conditions for said at least one of the copying operation and the scanning operation, and
