Image processing apparatus and authentication method having user authentication function based on human body detection

摘要

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.

主权项

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.
