Abstract

The information processing apparatus includes first authentication portion, human body detecting portion, de-authentication portion, and second authentication portion. The first authentication portion shifts the state of the information processing apparatus to a login state in accordance with a predetermined first login operation. The human body detecting portion detects a human body within a predetermined range from the information processing apparatus. The de-authentication portion cancels the login state when a human body is not detected by the human body detecting portion during the login state. The second authentication portion shifts the state of the information processing apparatus to the login state in accordance with a second login operation involving less operation steps than the first login operation after the login state is canceled by the de-authentication portion.

Claims

1. An information processing apparatus comprising:

a first authentication portion, executed by a processor, that shifts a state of the information processing apparatus to a login state in accordance with a first login operation in which login information including an ID and a password of a user is input;

a human body detecting portion that detects a human body within a predetermined range from the information processing apparatus;

a de-authentication portion, executed by the processor, that when a human body is not being detected by the human body detecting portion during the login state and an error has occurred in the information processing apparatus, stores the login information and cancels the login state, and that when a human body is not being detected by the human body detecting portion during the login state and no error has occurred in the information processing apparatus, cancels the login state without storing the login information; and

a second authentication portion that, when a second login operation, the second login operation involving fewer operation steps than the first login operation and involving only an input of the password, is performed during a period after the login state is canceled by the de-authentication portion while an error has occurred in the information processing apparatus and subsequently been eliminated, and before a next first login operation is started, authenticates the user in accordance with the password input in the second login operation and the login information stored by the de-authentication portion, and shifts the state of the information processing apparatus to the login state.

2. The information processing apparatus according to claim 1, further comprising:

a job storage control portion that stores in a storage portion job setup information concerning a job set up during the login state when the login state is canceled by the de-authentication portion; and

a job restart portion that restarts the job based on the job setup information stored in the storage portion in accordance with a job restart operation involving less operation steps than the first login operation after the login state is canceled by the de-authentication portion.

3. The information processing apparatus according to claim 1, comprising a display control portion that causes a display portion to display a re-login screen including either or both of a first operation key and a second operation key when the login state is canceled by the de-authentication portion during occurrence of an error in the information processing apparatus and the error is eliminated afterward, wherein

the second login operation includes operation of the first operation key, and

the job restart operation includes operation of the second operation key.

4. The information processing apparatus according to claim 3, wherein the display control portion causes the display portion to display the re-login screen when a human body is being detected by the human body detecting portion and not to display the re-login screen when a human body is not being detected by the human body detecting portion.

5. The information processing apparatus according to claim 3, wherein the display control portion causes the re-login screen to display a third operation key, and

the first authentication portion causes the display portion to display a normal login screen that allows the first login operation in accordance with operation of the third operation key.

6. The information processing apparatus according to claim 1, comprising an image processing portion that executes either or both of image forming processing and image reading processing.

7. An authentication method comprising:

a first authentication step of shifting a state of an information processing apparatus, with a processor of the information processing apparatus, to a login state in accordance with a first login operation in which login information including an ID and a password of a user is input;

a human body detecting step of detecting a human body within a predetermined range from the information processing apparatus;

a de-authentication step of, when a human body is not being detected in the human body detecting step during the login state and an error has occurred in the information processing apparatus, storing the login information in memory of the information processing apparatus and canceling, with the processor, the login state, and when a human body is not being detected in the human body detecting step during the login state and no error has occurred in the information processing apparatus, canceling the login state without storing the login information; and

a second authentication step of, when a second login operation, the second login operation involving fewer operation steps than the first login operation and involving only an input of the password, is performed during a period after the login state is canceled in the de-authentication step while an error has occurred in the information processing apparatus and subsequently been eliminated, and before a next first login operation is started, authenticating, with the processor, the user in accordance with the password input in the second login operation and the login information stored in the memory in the de-authentication step, and shifting the state of the information processing apparatus to the login state.
